I really appreciate how much time you guys put into this work. Even when things may not work out, you guys still give it 107%. Thank you!

I would 3D print a mold and use unidirectional carbon fiber as well to wrap around the pin end with a molded in metal bushings. The bottom end probably needs redesigning to take advantage of the material.

Unless lm mistaken, you need to close the resin intake line and draw full vaccuum before introducing the resin. This will help with air pockets, and let you fill the part more effectively.

one week i see a video saying carbon conrods are impossible and this week I see you guys going full send and trying it. love it.

What a gas.. you guys.. I wish I was young again I would come and hang out with you nuts. I worked on cars since I was 14 and rebuilt my first car engine.. before that I used to rebuild lawn mower engines.. Keep it up boys and thanks for sharing the fun!

I really hope you're all making it through these rough times. Thank you so much for continuing to experiment and entertain.

I call it a win as the fact it ran and drove I was amazed,I expected the second the engine started both rods would let go and it would lock solid,well done for the hard work that must have taken

Don't worry about getting it done right, just get it done! You guys are my hero's. From mechanical mad scientists everywhere thank you!

My thoughts is having 2 con rods that are so much lighter is causing the motor timing to be off, or those rods are trying to out rotate the other 2 non carbon rods due to their weight. I'm confident if you did all 4 rods you'd get a better result

Amazing work done, thank you for sharing this with us. Keep em coming! Bri

Here for the engineering not the politics

I always love you guys and seeing what y'all come up with Much love from Tulia Texas out on the farm

Nice idea guys. I'm liking the format of this one, more interactions with the team, I like to hear them talking about the process of their task.

What if you make the rods in sandwich layers say (10 or even 15) in the shape of the rods, I think it will be stronger. Also when laying, put the weave in a 45 degree angle each time you put in a layer and a resin in between.

great job guys! I appreciate the creative effort and originality!

I really enjoy your videos. I am a master mechanic in Canada and used to work at a Lada dealership in Ottawa. I liked the Ladas, very crude but tough and super easy to repair. Keep up the good work.

Wow incredible that you even could start it! I never expected that!!! I think if you adjust the shape of the rod to the new material and make it from one piece it will last.

Super cool project thanks for doing all the work so we could see. Im sure you could get them to work in some combination but that would probably take a couple more tries and alot of long hours working with carbon fiber.

i'm in the design phase of doing this for a lawnmower. need more material around the cap bolts especially if you have the space. a layer of resin after machining might of helped too.

these videos are the coolest car related videos I have seen on youtube, keep up the awesome videos!

Try CNC machining the conrods out of a block of multiple layered CFRP of same thickness as crank journal's width. I think it would do it Update: add optimization to tha mix, i.e run CF strands across where you need more overall strength

Love your videos, love your willingness to experiment ,keep up the great work bob, England 🇬🇧

You will have to fill the carbon sheet in Helically from the bottom (big end) inwards to get the layers in the right place to prevent the being nothing but resin and misaligned fibre holding the big end bolt fittings together.

YOU GUYS ARE AWESOME I LOVE ALL THE CRAZY IDEAS YOU HAVE AND THE EFFORT YOU GIVE TO ACCOMPLISH THE GOAL

It's the heat from the engine it softens the resin as it gets hot

"Look out! It is farting!!” Absolutely classic

21:24 Connecting rod: " see you on the other side, piston "

Kyocera a Japanese ceramics company made a complete ceramic gasoline engine in the 1970’s. It actually worked! The friction was almost nonexistent as the ceramic material absorbed oil and kept both the rods and pistons clean well lubricated at all times.

Definitely wanna see how a carbon piston holds up

Great channel, I am glad to see a VAZ2121 in other words a Niva, I am proud to say I am a former Niva 1600cc owner , I hope we’ll see much more of those here , keep doing what you are doing

Always very interesting.Thank-You G-54.

Amazing video guys, one of my favourites. Fantastic proof of concept. I bet if someone (or a company) with experience in carbon fiber parts, tried this, this could really become a viable option for replacement parts just like other car parts are made from carbon fiber. My other favourite videos from you guys are the starter motor as a supercharger, transparent radiator, crankshaft weld-up, and spring-loaded clutch! Keep up the great work.

This was amazing but they gotta try making them different ways and maybe with some carbon tow to increase strength in specific places also maybe try casting one with chopped fiber

What beautiful machine work you did on those con rods

This is just really amazing work!!!!!

You can work with Carbon fiber at room temperatures, but for it to become real strong, you need an autoclave. A kind of high pressure cooker.

Carbon fibre struggles to deal with the oily, hot environment, and its porosity can result in the churning of the oil. Also, its lack of density (which is also what makes it so light compared to metal parts of the same size) means it needs to have less compact parts, despite its high strength to weight ratio. The latter problem is what happened here.

So glad to see content being out out. And it doesn't look the subscribers are falling off anymore. The ones that left are the type ya don't want enjoying your genius content anyway

When he said only two, I was like aww damn, why? Then they show the process to make just one…I’m like yeah, yeah two is enough. Amazing work you guys

With the pistons being 1/4th the weight wouldn’t the counter weights on the crankshaft need to be lightened? Then you also run into the issue of the other pistons being heavier than the carbon fiber ones. I think if they made all 4 carbon fiber pistons with lightened crankshaft it might run better.

In other carbon fiber videos I've seen, each layer of carbon is soaked with resin as it's being laid down. Those videos aren't using vacuum, but it might be helpful if you have trouble with the resin penetration.

And for your next project - a concrete cylinder block! ;)

Just love these guys, and yes I'm sure all the major F1 racing teams have investigated the use of carbon conrods at sometime.. Very interesting..

Rev up your engines! This is the Scotty kilmer channel!

When he was machining the carbon fiber without a mask it made me bit scared for him. You don't want to breath it in, that shit is extremely evil.

Surprised this channel hasn't reached 1mil subs yet...they deserve it.

These guys are on the cutting edge. Fabricating carbon fiber parts... I've noticed their toolset expanding with each video, but this I didn't see coming. Makes me wonder if the ability to use carbon fiber will become more widespread in the future. That would be pretty cool.

What if you made a whole brick out of the carbon fiber and then cut and milled the rods out of that peice with additional material to compensate for the weak points?

Great work, just a thaught, perhaps layer pre-soaked carbon fiber sheets into a stack and then put them in a press until they cure and then CNC cut and mill the part to size. maybe the pressed higher density would add more strength?

It's impressive that you were able to make these in your own shop and have them last any length of time. There are carbon fiber con-rods on the market. But, they are very rare, very expensive, and not intended for street use at this time. After seeing carbon fiber brake rotors and pads, I figured it was only a matter of time before something like engine components would make their way onto the scene.

Looks good but complicated. I never got to learn it yet but seen some parts up at my college here in Ontario Canada. Keep it up guys great work as always 👍 👏 💪 110%.

To release parts from the mold easily apply a very thin lubricant to the mold like Vaseline VERY THIN before putting in the carbon fiber and after it's dried use compressed air around the corners of the part and it will literally fly off the mold :)

Check out forged carbon fiber. It can be very easy to do if you have access to a 3d printer to make the two halves of the mold.

Maybe compression molding and balancing of the shaft can work? This was a great experiment. Good job guys!

The strength of carbon fibre composite is in tailoring the layup to resist the stresses; you need to wrap the fibre around the eye (a metal insert fitted at the start of the layup). Similarly with the big end, fit metal inserts for the bolts, and wrap the fibres around those tubes to hold everything together, as well as wrapping around the bearing cap and along the length of the rod. You really need to use something like FEA to figure out how much fibre to wrap in which direction. It's like forged rods are stronger than cast, because the forging adds strength in the direction of the parts but cast is the same strength in all directions, which is down to the size and orientation of the crystalline structure.

The strength of composites is based on the orientation of the fibers in relation to the stress loads. Carbon fiber layups are not like an isotropic material and cannot be treated as an isotropic material. Careful thought and design needs to be taken into consideration.

Compared to steel, Carbon is 3x-4x 'stronger', in terms of ultimate and yield strength under a compressive load.... But it is not nearly as 'tough'. Steel can take more of a beating, since it isn't as stiff. It can spring. Carbon is too brittle, and I think a thicker connecting rod would have the same results. Carbon is ideal in a situation where it is constantly loaded, (bearing strength is incredibly high) but going from nearly no load on the exhaust stroke/intake stroke to very high compressive load on compression/power stroke is making the worst property of carbon come out: it is brittle. Also, the crank is balanced and counterweighted for a much heavier connecting rod. This extra vibration from the crank is not good for brittle carbon.

Wow that was interesting, reminded me of my engine build in 1966 a 1957 Olds for my 1947 Chevy. Carbon Fiber ?? I had used Carbon Fiber 1st in 1978 for CT Scanner patient support. It was fairly translucent to Xray and Stiff as well. But that was a static part. In 1985 I used Carbon Fiber again for a robotic arm for a large industrial welder. Light weight, stiff and easy to control Vibration. But not heated or seriously stressed in small joints. The Connecting rod as we saw; Has a lot of stress at the fasteners, and heat from the engine and bidirectional forces changing direction rapidly. It's a really serious strength test for any material. Certainly you picked up on the need for design change required to add material at the stress point. Thicker wider wrist pin and rod bolt areas. But using a whole-strand has strength mostly in compression. It relies on the resin to handle other forces. In one project the Navy needed tougher Buoys for the sea environment. They tried Carbon Fiber but needed it to be lighter. The used Mirco-glass bubbles mixed in with the resin for lighter weight but still strong enough, it worked. I used those micro spheres to reduce X Ray absorbing on the thick edges of the patient support/ It worked! Now in the case of Connecting rods I would think if Automakers can press connecting rods from Powdered Metal. You could mix powdered metal into the resin for added strength to the Rod overall and then instead of a weak vacuum, use something like an autoclave to heat cure under very high pressure the rod assembly. Now with added material in the weaker points (wrist pin and rod bolts) plus powdered Metal in the Resin and High pressure curing You just might have a Connecting Rod that could handle a gas engine. for fun. how about a carbon fiber Housing for an electric motor and see if you can replace the gas engine with carbon Fiber Electric Motor. Save the Planet but still build fun cars with powerful engines and motors. Stay safe, Stay well, keep thinking and doing, what else do we live for. Dennis in Virginia

great job building and testing it out.

I really enjoy your show and I'm sad to see what's happening in the world I hope you and your fellow brothers understand you being mostly lies God bless you God bless freedom let's see you build some crazy cars in the future love you brother

Lada ist kaput!

I love the simplicity of that engine

This is really interesting, you certainly have my attention on this one, good luck with your projects..

*What about carbon fiber gears in a clear manual gearbox???* Nvm, theres no way that would work, and it would be nearly impossible to precisely mold/cut gears into precise gears. Damnit.

cool experiment and possibly with a better stronger design professionally made they may work some day, but moral of the story for now is, metal connecting rods are stronger than carbon fiber rods.

i am amazed and happy with your work but im moore amazed and happier to see youtube leting you publish it.

14:56 vlad is asking himself on the left LOL

Id love to see you try this with the forged carbon fiber method... I have always heard that forged carbon fiber is much stronger

Absolutely awesome video.

this is the craziest car channel there is. These experiments will lead to a technological breakthrough one of these days.

Noe way the resin can withstand the heat

love your content and we care for you and your staff. My heart is with you and the kind other Russians that are on the wrong side of this conflict, Ukraine is not your enemy.

Great experiment. Thank you.

Great experiment! Thanks!!

First, yay!

Hey guys, I know I'm late to the party but I just wanted to say, whenever you're working with carbon fiber it's really important to wear good masks. Carbon fiber dust is really bad for you. Stay safe ya'll :)

Thank you I always liked you guys and your crazy ideas

Prepared worked for a pocket bike 2 stroke con rod in a single layup with an H prefabricated core holding the undersized bearings on center. Clamped the experiment within a 2 part CNC'd mold. For rare occasions with more time available than brains. Now back to our regularly scheduled entertainment for the climax.

Love the work you guys do and hope you guys try doing this again but next time use resin in bedded carbon fiber 👏👏👍👍

You guys are brilliant, really fantastic mechanics

i cant wait to see a carbon fiber flywheel! you guys are crazy 😁😁😁😁

Quite the fun project this was although I’d make them thicker, do all 4 for balance purposes and add that hard thick resin shine coating for rigidity and holding power, and make further enhancements for the connecting rod bearings. Well done nonetheless and amazing work!

... and while its an intermittent pulse of force lasting less than 10 deg of crank rotation, the rapid combustion force spread out over the top of the piston is roughly 21,000 psi pushing down on the rod. Also not sure what you used for resin, but most resins and epoxy will fail at those temperatures found inside an engine after warm-up, amplified by the lack of an oil cooler. Cool video guys! Always wondered if someone would try this.

Who else but Garage 54, thanks guys.

I love when he is making knocking noise with the Russian accent :-) Great stuff like the usual.

And again another cool video.

Excellent adventure Cheers guys

I won't be surprised if someday I come in here and find these guys have built an entire engine from scratch! machined out the block and everything.

Carbon flywheel for maximum danger! xD

Full carbon fiber lada when?! Jokes aside, i dont even know how ou guys come up with such crazy ideas, i love them.

I love your videos. I burst into laughs when he makes the sound of the engine 17:15

It will probably require 2 molds in combination to form the 2 halves properly with vacuum and heat to cure properly. Also you may need to make it thicker in material initially before any machining is done. The whole thing needs be made into as solid of a piece as humanly possible to ever stand a chance. Cross layering is essential for strength to carbon fiber.

That is some Heavy engineering right there.

garage54 making the best content.

I love the unconventional things they try. It's the inner geek in me but I saw the thumbnail and knew it was these guys. Love your videos.

That was awesome!

"I don't think we're going anywhere... Or are we? No need to be afraid!." Love you Vlad!

The fact it didnt snapped them 3 sec after startup is amazing!

Just realized these dubs are like audio book what can be listened while thinking something more important, like turbos.

I like when Ivan is on camera and narrating ... He's a badass
