Making carbon fiber body for car, need advice.

I am part of a group hat has been working on making a carbon fiber body based on the the above images. I was wondering if vacuum bagging pre-preg twill weave around this would prove a decent method.

You are judged not by what you know, but by what you can do.

Cannot see the image. If you can, use the engineering.com link the way berkshire says.

Twill will go round some double curvature. Five- or eight-harness satin will deal with more severe double curvature. Twill will be a bit easier to make reproducible if hand operation, as it will deform a bit less (less sliding over one another by warp and weft fibers). If you are concerned about the final as-cured curvature you make need to either automate to a degree (pick and place, perhaps) or at least use laser positioning for each section of cloth. Won't say more 'til I have an idea as to what you're after. I'm assuming it's a car!

Molding and bagging your laminate on the outside of a panel will only result in a part with lots of wrinkles and sagging on the cosmetic surface. It is very difficult to produce a high quality surface finish on composite body parts. To achieve the level of smoothness typically seen on most automotive body panels, it will require significant amounts of hand finishing.
