Carbon Fiber Twill Resin

Hello Everyone,

Has anyone had any experience working with carbon fiber 2x2 twill (cloth) and resin? I had a question about it if you would be willing to answer.

You can just post here if you have. I'm not sure how popular this stuff is. Hopefully someone has had some experience with it.

Thanks!

What is your question? I don't have experience with it, but I don't see you getting any bites without posting the question.

Basically, I'm just wondering how it gets applied. I know that the twill is laid on whatever it is being applied to (i.e., trim piece), and then the resin comes into play. I also know that it has to be sanded, but I was wondering how much and with what grit.

My guess, again just a guess, is block till flat with something around 200 on a DA and then work your way finer and finer until it shines. Any paint guys would be able to answer this for you.

If you're not vacuum bagging the parts (increases strength, much, much better for structural parts) then this seems like how you would go about doing it:

Thanks for that vid. I guess the only question I have now is how to overlay a part. The guy in the vid was using a mold, but I would be overlaying an existing part with the CF. It is basically reverse the steps he showed.

I also wondered about this. I have the oem performance diffuser and I want to carbon fiber to the finned section in the middle and the upper corner sections. Is the process as simple as laying the fabric, adding resin, and sanding?

I've used the stuff on small areas of my bicycle and in the past have used it in stereo installs. Basically you just apply resin to the surface (otherwise the fabric won't stay). Then apply resin over it and sand. The hard part is to not mess up the weave when you're laying it and when applying the resin in getting it as even as possible. If you have bubbles or anything in the resin, sanding won't fix that. And make sure you have a thick enough coat of resin to sand.

sweet, I'm probably going to give it a try as a side project over the summer.

#1 requirement = PATIENCE

I made a custom splitter with my own CF and resin for my old A4 and fuck. that was a bitch of a project. Makes you really understand the higher labor cost in developing a CF part.
