Just wanted to help! Aluminum and carbon fiber touching will cause galvanic corrosion. Anodize or coat the aluminum with something. Ultimately the part will fail because of the galvanic corrosion. Hope this helps! Love your channel and your a rock star with engineering💪🏼

Awesome video. I've been curious about carbon fiber.

Hi Jeremy, a few points: - For safety I was told that you should always use a respirator and/or work in a well ventilated area when dealing with epoxy resins. It isn't an issue immediately but a professor of mine who built composite aircraft as a hobby mentioned that the long term buildup of vapors is detrimental and proper PPE / ESC should be used when regularly working with epoxy composites. - Another cool feature of the more textured peel-ply is that it leaves the cured surface ready for bonding with other composite parts. If you wanted to add more material or join two already cured parts that peel-ply saves you the effort of prepping the surfaces for more binder material. - You kind of touched on this but in addition to weave patterns being able to affect the directional strength of the composite, you can also stack multiple layers of different weaves to 1) provide more thickness = more cross-sectional area in a classic bending load = higher strength and 2) have multiple directions in which the stands are aligned with. If you know the forces the part is expecting, you can have most of your layers supporting that situation but other layers aligned to resist torsional forces. The example I would go to is with the checkerboard weave, you can offset a layer by 45 degrees to get more overall strength and stiffness. Very cool video!

I have been 3D printing for years and never thought about the concept of external model vs internal model stress. Great explanation - makes a lot of sense.

I have been working in the composites field for several years and just wanted to talk about other materials as well : - Glass Fiber - cheap, brittle (doesn't handle shocks or abrasion well), very light. Mostly used for boats. - Carbon Fiber - medium priced, sensitive to abrasion but resistant to shocks, medium heavy. Mostly used for air-related pieces (speed cars, tuning, aeronautics, space) - Titanium Fiber - high price, resistant to shocks and abrasion, quite heavy. Mostly high-standards pieces (aeronautics, space, some fine engineering stuff). Yes, this basic hint is not a hard rule whatshowever because you can use different weave patterns (as described very well in the video), use different layers with different materials, mixed meshes and so on... I just mentioned it to give a general hint for the viewers. Choose your fiber materials according to the project you are making. Once you understand how it works, everything will be simpler. Multi-layer is also possible but harder for beginners as you have to deal with multiple constraints. As explained briefly in this video, bubbles are your worst enemy, especially if you need uniform resistance on a surface. Generally, the quicker the hardener, the hotter it will get, which can also have an effect on the mold you are using (deformation due to high heat). The resin that you use can make a huge difference as well (UV-resistant, thermal range of use when finished, and so on...). Please use masks, eye protection (specially if you sand it because it creates very tiny particles that can be very toxic for your lungs) and all the other protections you might find useful to protect yourself. The fibers are not that harmful but the particles and the vapours can be. Thanks you for the video, I really enjoy people talking about this subject, as it is indeed very interesting.

I love your sense of humor in the face of mistakes or problems. "If you don't learn your lesson the first time, apparently, two or three times is still not enough." 😂😂17:42

New viewer here and I just wanted to say that I really appreciate your approach and honesty about mistakes and the learning process. Great work and I'll be watching more in the future!

Your enthusiasm for learning powered by curiosity is infectious. Your presentation style allows me to imagine we are best of friends, working together on projects of equal interest. Thank you Jeremy.

Nice job and informative video. One thing you might want to be aware of if you're not already is "amine blush." When you're using epoxy it creates a shiny surface when it dries called blush. You need to wipe this down with warm water and a Brillo pad or Scotch-Brite before anything will properly adhere to it. You can actually see the shine disappear as you scrub it.

One of the problems I had designing and printing 3D plastic was getting fits to match measurements . After some experimentation I discovered that I need to think of all measurements in terms of 0.4 mm - nozzle size!- It made a big difference in fittings getting things to line up.

Regarding the cost of Carbon Fiber. The carbon fiber itself is like buying any other fabric... by the yard. You can buy as little or as much as you need. Think about it this way, you can make a part as strong as steel, as light as plastic, and all without the skills or cost of CNC, a welder, etc. If you can use a pair of scissors you can make it. That is amazing to me. I think its great for DIYers and the budget. Also please try out the sponsor as that really helps the channel. You will get 10% off your first order with Fictiv - bit.ly/3YOmVzF. Use Coupon code: Fielding

For really complex curves, try cutting your cloth into triangles. That will allow for more a lot more flexibility. Also, you probably don't need to worry about it, but different hardeners (fast cure versus slow cure) can affect the final strength of the part. Not always, but something to check just to make sure.

The best Videos are where people show how they faild AND how they fixed it 👍 thats the best value anyone can get out of the videos about any project 😁

You have done a great favor to all the DIY with your channel . Thanks for sharing your experience, thaughts and professional advice and support! Much love from another Brother.

For something like the knight, you should make a negative mold (probably in this case two or more parts is easiest for layup) and then polish the interior to a high level of finish so that you can layup the carbon fiber directly against it and get a perfectly smooth outer surface. The separate halves are then joined afterward and the seam can be polished smooth (especially since this piece is mostly decorative and doesn't require high strength).

Thank you for being vulnerable and showing your learning journey! Seeing you face challenges, persevere, think and overcome is inspirational. As we oldies say down-under - ya blood's worth bottling.

I think this video illustrates a rather important and easy to overlook pitfall (that I fall into time and time again..): don't work to a deadline but to a result. The pressure of counting days unconsciously creates some sort of stress that ultimately makes everything take longer and cost more than a more relaxed approach.

Also i would recommend using a 0.8 mm nozzle for multiday prints as 9/10 % of the time it will cut the printing time in half and wont effect the strength to the print exsepcaly since your carbine coating it.

If you haven't seen Mike Patey's videos from his "Scrappy" build, he is an absolute genius with carbon (and most everything else). You two would have a great time getting together. I know he mentioned corrosion issues when mixing aluminum and carbon in one of his videos as well.

I have learned over 4+ decades of working, is that hardly any project is completed within budget, on time, or completely witin specifications. That is still an admirable goal, though!

this is SO useful for the beginner. Honestly, your mistakes are helpful too because they show failure modes a beginner might hit. This is great, thank you!

I have wanted to do this for the longest time. I am so happy that you made this video. When I saw the title and that it was YOU, I thought, "this is going to work! Jeremy's videos are always very helpful and very useful. Thank You!

Closest to this I've done is fibreglass repairs to Kayaks back when I was young enough to fit in them. Interesting to see both the similarities and differences in what on the surface looks like it should be a very similar process. Thank you for taking us on your journey over the pointy bit of dunning kruger.

One of the best DIY videos I've watched in my entire life. This is the kind of video a normal person relates to. Followed the instructions, took care of everything, double checked (or at least believe you did check) and things go wrong. You've made a mistake. That's the value of the videos that shows the real situations, how to cope with it technically and psychologically. How to learn from your own errors. How to mature and overcome the frustration. How to proceed by pure will, by innovating, by luck. Finish the project and immediately think on what could be done better or what will be the next project. Those videos full of happy paths when everything seems to work in the first try and breaking records, personals or not. They feel the normal guy think "it's too much for me". By been courageous and showing and sharing your mistakes, by sharing your feelings about and thru the project, is what makes this video most valuable. Congratulation on the job well done. And 10 thousands of my best thank yous for sharing with us.

Mistakes are incredibly instructive. Thank you for including them in your video.

Love what you do, and can relate so much: "I should've done something simpler, but it wouldn't be as much fun."

I appreciate that you do leave in the mistakes. And point them out. I tend to be too hard on myself for mistakes.

I love that you keep the hang ups, blunders and mistakes in your videos. It sheds light on the level of detail required and shows it can't happen right the first time every time. Keep up the great videos.

Jeremy, my friend Craig has a you tube channel called Throttle Stop Garage. He is making carbon fiber fenders, hood, trunk lid and many other parts for a 1967 Volvo tudor sedan. He's Canadian and VERY meticulous with his bagging and vacuuming. His trick is to pull a vacuum and draw resin into the bag. You really need to watch him, you'll learn a ton. Good Luck and keep the vids coming!

Awesome video. We can tell you love us because only a person truly in love would go after that level of complexity for their first carbon fiber layup, and do it on camera. Don't stress about getting content to us sir, we are not going anywhere. Btw- I totally appreciate the realism of affixing things to the bench, etc., etc. That level of honesty is refreshing.

@Jeremy Fielding watching the 4th video now and I think I know why I'm hooked, it is the way you "teach" things, it reminds me of the late Neil Peart (drummer of Rush) and the way he approached his work, very detailed and meticulous, again thanks!, I'll stop messaging you now, but won't stop watching, have a great day!

I was looking for a beginner CF video and was so happy when I saw it was a vid by you ranked first. I always learn the most from your videos.

ADHD was going hard today until I saw this video and got hooked on watching your process. First time seeing your content. Subscribed.

I just want to say I watch videos on creation of carbon fiber parts… 3d printing… and just self education and learning stuff… I am a pretty reserved person with taking risks … watching your videos … attempts creations success and “failure”which is just progression so please don’t take that word as negativity. We don’t learn right away… and you have truly inspired me to step out of my comfort zone and take a chance on my self to start trying something I always wanted to do. So truly thank you. I appreciate your video and your words. Thank you.

You could use rubber membrane press or some sort of rubber sock arround the knight (those can press tight areas without wrinkles) and you could model holes into the knight so that epoxy would flow into the part. So you would not need any peel ply (silicone membranes are self releasing and you would have "dry" carbon), breather etc. You could also get a 3d printed part out of it to make it lighter by heating it up. Also try gluing carbon onto the part with car spray glue, then use silicone kitchen brush to wet it up (reusable) and then pull a vacuum and work epoxy inside the holes by hand (diy autoclave carbon). The mould could be done of hard wax to be mented out in the end

You strike me as a genuine dude... definitely someone I’d trust.

The KZfaq Algorithm did a good job this time. Got recommended an older video a few days ago and immediatly had to subscribe! Amazing conten!!! Keep up the wonderful work!!!

This is such a good video. It is good to show a great concept but also show the struggle to get proficient. We all struggle at the beginning of learning a new skill sometimes. It can be a demoralizing phase of the learning process if it seems like I’m the only one who just isn’t “getting it”. You rock. Thanks!!

I have never seen your content before, but you seem so chill and genuine. Got a new sub for sure.

I had my first attempt at CF layup last week, and it's great stuff to work with; It's expensive compared to other composites, but not as much as it used to be (I guess due to more companies now making it), looks very cool once finished. The only issues I experienced were loose tows on the edge that kept fraying off, I kept all these and chopped them up to make some forged-carbon-like material just for fun. Oh, and also forgetting to put enough of the right mold release on, which meant I spent ages chiseling and sanding to separate the parts.

Fantastic video. There are a million different ways to get to the finished product with CF. I visited several different production shops to get clues to the most efficient process. So many different takes on reaching the same result. Love your process and approach. More, more, more!!!!

I have never laid up CF however, I have seen Mike Patey do it, so I'm qualified to say this😁: You need to electrically isolate the aluminum from the CF, otherwise the CF will destroy aluminum via electrolysis.

Extremely educational , very inspiring.! Not afraid to admit mistakes, the mark of a good teacher. Thank you so much

there's also the forged carbon fiber process that you can make molds with 3d printing. I tried following Easy Composite's process and it needed some minor modification but it's totally doable. For certain parts the forged process is better than hand layup (especially the small stuff like the brake lever they made); I made a shift knob for my car using the forged process and it looks stunning. Way more unique than regular woven fiber.

I've been trying to figure out how to make something difficult out of carbon fiber for a while. I came up with a Plan B that I might actually be able to do. You just gave me an idea to combine both ideas so I can make the first one work. Good stuff dude.

💥💥OH MY GOSH 😮❗️ You’re such an amazing wonderful Teacher,Inventor,Father and Husband 😊. I ABSOLUTELY LOVE WHAT YOU DO 🎉🎉🎉❤🎉🎉 You have the luckiest kids in the world 🌎. You Teach us in an awesome way that just makes sense. Keep on keeping on my KZfaq friend. Blessing’s, Carlos ✝️🙏❤️😊❗️

Love how your content is fast enough for people with knowledge already but also explains it to fast learners that are beginners.

I worked at an aircraft composite parts company and learned a lot about various materials and usage and the processes to make the parts. It isn't easy but can be done by a DIYer with proper instructions.

Very cool. You’re never too old to learn a new skill. Thanks for sharing that journey with us.

OMG. My first idea/thought at the beginning of your video was wrapping 3d printed objects in carbon fiber. Then you mentioned it out right! We must be on the same wavelength. Awesome video!

Thanks for posting the ilmistakes and "days lost" text. It's very helpful to see the ENTIRE process.

Good job showing all your success as well as failures, this is real life; any fabrication includes things that work, and things that do not work, all part of the process. It makes sense to always apply the resin to the carbon fiber, to optimize the resin impregnation into the fibers of the carbon.

I love how you create your videos and show mistakes, especially when you explained about the robot arm and why you chose to switch over to another project instead of just releasing a video of the chess piece.

i have always wondered how to use carbon fiber, i didn't know it was as easy as fiber glassing, thanks Jeremy

Jeremey...Really glad to see another video! 85 views in TWO MINUTES!!!!

Once again, the curiousity of my younger days has been been awoken! Thank you, Jeremy! Excellent job!

It's a very nice video, because, and please don't take me wrong, you just show all the mistakes that DIY enthusiasts (like me) might and will probably do, we definitely learn more of our mistakes than from our successes! I'll be following your channel Jeremy 👍

This is pretty wild. Back in a previous life, I was planning on building my own wind turbine, with some fancy blades molded from fiberglass. This process seems pretty similar, although i was thinking about having a two piece external mold, and a bag inside inflated with air pressure. You've definitely gotten me thinking again.

oh man, I almost thought you'd just be talking about 3d printing with CF infused filament... but I love finally seeing someone make a proper almost tutorial on how to actually work with raw carbon fiber

THIS! This is why I subscribed to your channel, Jeremy! Every mistake is education. Knowing the few ways that work best is important, but knowing the many ways to fail is equally important. Thanks, for another great vid, brother!

I really like your honesty about building things, every small failure is a learning opportunity! Great content, thank you!

I've watched people build carbon fiber planes, but never thought of wrapping a 3D printed part like this. This looks great for small runs where a little extra weight doesn't matter.

I have always enjoyed your self-depreciating sense of humor. I spent about ten years designing, then re-designing, 3 different CNC machines. And each new design started out as the final re-creation. Actually I redid everything countless different ways chasing down the next problem. People watching you shrug off mistakes is a very important lesson. It's been said that in life, 95% of the choices we make can be "do-overs". We get another chance to make another mistake.

I really wish you lived close to me! I own a small automotive composites fabrication business I would’ve loved to show you much easier ways to tackle that robot arm project and still achieve the desired result. Like you said it was an overwhelming first choice but with a few tricks you could’ve absolutely gotten it done in a much more timely manner!

Jeremy, you did your ususal outstanding job for those of us on the first rung of the ladder -- Thank You for another excellent video!

That take away, "learn something new". I took on a project to make a part for my adventure van, it was going to involve printing with ASA, and I've only been learning 3d printing, relearning CAD in general, and learning Fusion360 for just about a year. I've learned so much about part design. I've learned so much about my printer, working with the higher temp filament, getting good at bed leveling, etc. I've learned so much even just about all the little details in the slicer settings! In the end, the part is buried in lap sealant and barely visible, but I'm so happy I took it on and am energized to try even more new things!

Great video!! And can we talk about that seamless transition into the sponsor..? Relevant ads should feel like content and you demonstrate that perfectly.

Quick tip on the vacuum bag. surround the perimeter of with a piece of rope inside the bag with the ends at the end of the vacuum hose. It helps distribute the vacuum without the bag collapsing.

I trust you've already gone through most, if not all, of this, but: There are a few factors to consider with 3D printing dimensional accurate parts. The process causes some shrinkage, and the calibration is going to be important for each new material. (Brand to brand, and even roll to roll). Part of that process includes verification of the steps each of the stepper motor takes to move a specific distance (defined as steps per mm, most commonly) for each axis, and the extruder stepper motor(s). These are usually accessible through the slicer profile settings, but some models require a deeper dive into the firmware/internal settings. Once you verify the steps are accurate for real-world movement (which is fairly rare out of the box), the next step would be scaling compensation for the shrinkage itself. Personally, I like the 100mm in each axis. It makes the math easier: 100/(actual print measurements)=(decimal representation of scale [1.xx=1xx%]) I hope that this is helpful to you or some of your viewers. There is more info available online in a TON of places.

I really enjoyed this video. Mistakes are just as important as victories. You have a killer attitude. Love it.

Excellent demonstration of the forces on a beam.

So glad to see you post a video on KZfaq, your videos always help scratch an itch and make me want to try new things.

Thanks for showing the reality of life itself “YOUR GOING TO SCREW UP BUT THERES ALWAYS A WAY YO FIX IT AND LEARN SOMETHING “

mistakes and all you are a very intelligent person and very good at designing. I am very impressed by what you do all in all just a great job!

Thanks for including all the mistakes in the video! I think those are the most valuable parts for DIY people because those always get your brain to work relative to your own projects.

Very cool. I've never really thought about making something with carbon fiber, but I'm tempted to try it now.

I just watched the first video on your channel. Amazing content, amazing engineer with a great personality! You’re an absolute asset to any team or company.

Appreciate including mistakes 100%.. I think we learn _more_ from seeing the mistakes than seeing the successes.

Big hats off to you, for showing and highlighting all the mistakes in good and light hearted manner :) It is hard to overcome the fear of failing and I think even more so than ever, when we're normally only spoon-fed the perfection of social media stories.

Aways been fallowing your content and I admire your honesty. Thank you for the video and all informations you provided!

I don't see myself using these materials in the future, but it's nice to see that it's not as difficult as one might think. Just take your time and don't be afraid to screw up...every mistake is a moment to learn 👍

beautiful... can’t hate on the process of getting more knowledge. bravo.

Thank you! I am glad to see that I should not give up, just because I am not perfect the first time!!😊

Learning from mistakes!!. Great way to learn to be resilient. The key of a real entrepreneur and maker. Congratulations and thanks!

The one thing that we all learned this month is you cannot make a carbon fiber submersible

Thanks Jeremy, I have wondered about using carbon-fibre instead of forming metal pieces. Although your robot arm plan didn’t survive first contact with reality you still demonstrated what can be done by DIY makers and that is inspiring.

I am really enjoying this video! I strongly support your statement at the start where you say you're not an expert, but did some experiments and wanted to share your results. That's such a good attitude! I love it!

I name thee: Jeremy the Adventurous Engineer! Love how you show your learning journey. Thank you so much for these videos.

I love this guy’s honesty

"Sucking at something is the first step towards sorta being good at something” - Jake, The Dog.

Just want to bring up an issue when combining aluminum and carbon fiber. It’s called galvanic corrosion. There needs to be a non conductive layer between the metal and the fiber such as fiberglass or a coating on the aluminum. Great work by the way and a fan of all your projects.

I have a project for you. At the end with the chess piece mfg, your vacuum pump was in a few frames and I saw the oil mist wafting up as these pumps are prone to do. The first time you have to run the pump for over 15 minutes you will discover the roots of my challenge; to create a low cost filter that would remove the mist. I found this benign appearing fog to be a real nuisance and finally had to make a bracket connecting it to an old shop vac hose and channel it out of an apartment window (I gave up on building a filter with materials on hand after a couple of tries). That solved the problem until a neighbor noticed what he thought was smoke coming from my apartment at 2:30 am! Very exciting. A filter would resolve the issue and allow for indoor 24 hour use of my pump (wood stabilization using Cactus Juice). I will get to carbon fiber use when I can clear other projects off the bench so thanks for the info and encouragement on that. We have very similar passions that drive us to learn, share and explore. All my best to you.

You can also get carbon fiber/kevlar cloth. I used it to build a 19 foot kayak in my garage, using a mahogany kit kayak as a mold. The kevlar adds a different kind of strength and makes the end product a lot less brittle. Used a fiber core material about 1/8" thick that contained glass beads to reduce waight. When landing my kayak one day, there was a 20 pound rock in my way. I reached over the side of the kayak and picked it up, throwing it up over my shoulder into deeper water. Oops! Misdirected and hit the top of the back deck of the kayak full force. There is a dent, but the structure of the hull is intact with no real damage. I believe carbon fiber alone would have shattered at the impact point. You can MIX the slow and fast hardeners to get a custom set time.

Always learning, thanks Jeremy!

Thank you, I've been hoping to explore carbon fibre one day.

Brilliant, Sir! Loved the part with glueing everything to the table 😜

Thanks. I needed this video break sir, as things are going wrong on my eboard rebuild😆 You're truly an inspiration bro. Keep up the good work.

Jeremy, thank you for continuing to make videos revolving around STEM. Its inspirational to have fellow engineers of non-caucasian decent. Additionally your relaxed attitude and mellow speaking dynamic draws me in on your videos.

Crazy how tech has made everything so easy

one thing about the strings that come off and any access scraps that you have - keep them. I cut them up and use them for forged parts. that will save you money. or, you could sale them.
