Title: Carbon fibre "vac bagging"
Post by: AdeV on July 16, 2013, 08:13:09 AM: Hello! :wave:

I'm after learning how to do carbon fibre dry layup/vac bagging/resin infusion, to make race car parts & such like; mainly panels I suspect. Can anyone recommend a good book on the subject? So far, most of the glassfibre/carbon fibre books deal with wet layup, or briefly cover vac bagging carbon fibre which needs baking (I don't have a large enough oven to cook a big CF piece).

Supplies appear to be readily available here in the UK, there's even one company offering a "complete vac bagging starter kit" c/w resin, cloth, vac bag stuff, vacuum pup & fittings, which sounds rather good.

I guess instructibles & youtube will also be good learning resources.

No books, but plenty of videos. I will post up some links when I get to work.

Video 1.

FiberGlast (http://www.fibreglast.com/category/Learning_Center) has a learning center that has a ton of info. Specifically a video SERIES (http://www.fibreglast.com/fibreglast_how_to_vacuum_bag) on bagging.

I have found that the instructables and maker crowd are a little less versed in good instruction when it comes to bagging.

I think he must be cheating. Polishing a black mould with that type of polisher should leave a black horizontal stripe accross his spotless white shirt. :Doh:

Not done much of it but wet layup with carbon fibre cloth tape was the same as using glass fibre reinforcement. As noted though the professionals use pre-preg which is a whole different ball game. Pre-preg is much less messy if you can use it but you have other problems with it like minimum order, refrigerated storage and higher cost etc.

Post by: AdeV on July 17, 2013, 05:01:28 AM: Cool, thanks! Those videos were a great find, and on a site I'd already briefly looked at (just for the price of CF mat as it happened.

Of course, one thing he didn't cover (crafty....) was what happens if your panel is larger than a single sheet of CF.....?
