Please note - In the price I have not included the cost of re usable things like the mould and vacuum storage bag, which will last hundreds of parts if well maintained.

Recommended to me by the algorithm. I do a lot of fibreglass boat work and had always been put off vacuum bagging by the hassle of making the bag, connecting the separate pump, etc etc. Your video is brilliant. Such an easy approach and very cost effective, not to mention cutting down on plastic waste. Thanks for sharing - I look forward to testing this weekend👍

Be careful about using your bare skin with epoxy resin! It is a sensitizer, which means over time it can make you more and more allergic to it, to the point it can cause serious problems to be around it.

What a remarkably good outcome, I had always wondered if a domestic or industrial vacuum cleaner might work in this application.

I'm always amazed how you make it look so simple. Thanks for sharing once again.

Very cool. Thank you for sharing your knowledge!

Great video as always!

Very helpful I may give this a try and make a front license filler plate for my 90 corvette.

That's looks great bro!!

I'm intrigued by your methods! I need to try skinning the way you do and be patient with the initial layer you start off with, the end product is fantastic!

Thats a great idea 👍

Awesome!!

Hello, it worked now and is ha solid material, but the gel coat is still sticky between the carbon and the original product. What can I do that it isn’t sticky anymore?

Do you have the composition of the breathable cloth? I'm in Canada so it's pretty expensive for the shipping if I buy from the link you provide

Merhaba. Epoxy gel coat ve carbon fiber ile yapılan parçalar güneş ışığında dış ortamda şekil değişikliğine uğrar mı yamulur mu?

Hmmmm, when I did it, I missed the gelcoat first. Interesting. I want to try the resin infusion method next time for myself anyway. Just got a used Gast diaphragm vacuum pump to use.

I've tried this method on a piece of mine but I am struggling to let the carbon fiber adhere to the mould. What should I do to let the carbon fiber adhere perfectly to the surface mould?

Is the surface of the carbon fiber smooth Sir??? And is it strong enough to withstand minor scratches?

What is the purpose of the gel coat in the first stop. Stronger than epoxy and polished better?

So there's no heat treatment required for this process? How long did you leave it under vacuum for

I have learned so much from your channel! I am in the process of creating my own mold design for a trunk wing spoiler. Would the method with the vacuum bag be good enough for a more complex detail? Would the vacuum bag create enough pressure for the carbon to get to the contour of a more complex mold? Anyway, I am almost ready with the mold and waiting for the carbon delivery so will find out myself but any hint would be appreciated! You are a blessing for the carbon enthusiasts community!

dont have epoxy for carbon idk is it gone work with polyester hardner ?

Great Minds think alike!..I was thinking the sam thing but on a bigger scale for door panels and hradliners

So with the vacuum process do you leave the vacuum on for a certain amount of time? Or do you seal the bag then turn it off

what is the name of motor and cutter ? great work

How did you get it to release from the mold

Hello excellent job thanks for information, I was just wondering how much time you wait after last gelcoat, before applying epoxy resin? Thx

I was always curious if you could use those home vacuum bags for this. Guess so! I have a project where I want to make a panel that is 78"x140" I was planning just to do a wet layup but I think the vacuum is important. What do you think would be the best way?

@Carbon Workshop hello I have a question: we may not see it in the video but do you pass your preparation in an oven? if so how long at how many degrees c?

Nice job! 👍 Can I ask where you got the little blue plastic attachment you use to attach your vacuum bag to the vacuum cleaner? thanks

Looks good quality, do you make anything for the rocus rs

hi! i love and learn a lot from your channel! i have some questions and correct me if i wrong. 1. the method u showed is kind of similar to achieve prepreg end product but without using prepreg carbon right? only use normal carbon fibre clothes. right? 2. can the parts like above video be cured again in oven/autoclave after overnight cure to achieve higher strength? thank you and pls make more videos! love your channel!

my only question is how did you cap the vacuum bag without releasing the pressure?

After you trimmed the carbon fiber, you should've sealed the edges with CA glue. Not sealing the edges can cause delamination.

Great result, i didn't get well how much time rest among gelcoat and first layer of resin, and then, i saw that you pull the gelcoat after it rests for 10 min, do you apply other gelcoat in that moment? or simply you pull what you have applied before? Thank you

which one the best polish compound between McGuire's,3m and g3?

what is the straight aluminium sanding block that you use ? thanks

may i know what do you apply so the fiber and resin dont stick into the mold?

How strong is it compared to oven baked? It certainly looks the part.

Great content and instructional videos. Any suggestions where to get some of the products you recommend here in the US? I checked with Composite Envisions here in the States, but they apparently don't offer a polyester gelcoat that is compatible with epoxy resin. Anyway, any suggestions would be appreciated. Keep up the great videos!

Hello, can I know the white cloth name?

what would happen if you just bag it without peel ply and without breather cloth

I think I know why, but why do you add a gelcoat layer first? I guess just for shine/hardness/UV stability for the outside? What brand gelcoat is it, and is it hard to get one compatible with the epoxy?

How many long u vacuum the mould? Until let dry or what?

So let's ask this. These vacuum bags I see go for cheap Amazon for about 34$ US with the blue cap. Would you say these same bags can be cooked at 120° F? If it was discussed already I am sorry

hi! someone know a web site in EU i can buy these products?

AFAIK, The vacuum level achievable with domestic vacuum cleaners and vacuum bags is typically not sufficient for a good quality wet layup process of carbon fiber epoxy parts. This process often requires a higher level of vacuum to ensure quality and structural integrity in composite materials like carbon fiber. In the wet layup process, a vacuum is used to: 1. **Remove Air Bubbles**: To ensure there are no voids or air pockets that can weaken the material. 2. **Ensure Proper Resin Distribution**: To achieve a consistent resin-to-fiber ratio throughout the part. 3. **Compact the Layers**: To create a dense, uniform laminate with good fiber-to-resin adhesion. The vacuum level required for this process is typically higher than what domestic vacuum cleaners can provide. Industrial vacuum pumps, often used in composite manufacturing, can reach vacuum levels of about 99% (or 0.1 kPa), which is significantly higher than the 80% (or 20 kPa) achieved by household vacuum cleaners. In summary, while domestic vacuum cleaners can create a basic vacuum for general household tasks or simple vacuum bagging, they are not adequate for the more demanding requirements of carbon fiber epoxy wet layup processes. For such applications, specialized equipment designed to achieve and maintain a higher vacuum level is necessary.

How many minutes did you vaccume it sir?

Круто!!! Но что с этим делать ? :)))

is it important bake in the oven the carbon? i see this step in a lot of video. Sorry for my bad english but i am italian 🥲

Great work but you should of wore gloves when laying both the ply and breather. A hand reaction may not happen instantly but can be bad in the long run.

Does using vacuum cleaner really works instead of pump?

How long does it have to be under vacuum?

Hello, I left it in the vacuum bag for 10 hours but it still was soft and sticky. Did I do something wrong with the mixture or was it to short in the bag?

5 pounds plus 10 thousand hours to master the art.

While likely accurate, your cost calculations leave much to be desired IMHO. I'd prefer to see initial outlay values rather than cost-per-use or cost-per-piece values. As I see it, that's how most folks would have to begin.

I cant believe that the materials are so cheap

You forgot to add your time to the cost price, as well as the time spent on mistakes, before obtaining mastery. This is where the cost price and the final price of carbon are formed =)

Great video - "ANNOYING MUSIC"

its spelled V...CUUM

no gloves xD
