Re: Carbon monocoque

I get requests now and then asking if I could make a GT40 body in carbon fiber. When I work up a price, that's the end of it! The price doesn't justify the weight savings to most people.
The trouble FFR had and as do all fiberglass fabricatores using a "wet layup" system, the material is black and you can not see any air voids behind the fabric when laying it in the mould. With FFR Roadster body I had, the amount of body putty I had to use to fill all the air voids made the body weigh more than a fiberglass body. Kevlar has to be vac. bagged. It's pretty tough to lay up Kevlar using a "wet layup" system. It just doesn't work like most fiberglass products when using polyester resin. Kevlar works best with epoxy resins and the same with corbon.
