I have fibreglass bodied, tubular chassis ford thunderbird (i.e. doorslammer) drag car with central trans and driveshaft in the conventional manner.

The internal panneling is a mess and I want to tidy it up with a new transmission tunnel to enclose both the trans itself and the propshaft. The shape is complex and it will need to be in sections that can be slid into position amongst the chassis tubing.

Normal method would probably be to use aluminium sheet but I'd like to use carbon if poss - largely for aesthetic reasons if I'm honest.

I can see how the wet lay process over a mould might be OK for this but I'm struggling to think of the best way to make a mould. Possibly the cellular aluminium sheet could be carefully bent to shape and then coated with wet lay carbon?

If not, I need some sheet material that can be formed to shape in situ then hold its shape while it is extracted from the car before applying the carbon. I guess thin aluminium might be Ok but I'm not sure it can be bent to complex curves that would hold their shape.

I need some wonder material like thin, non springy, slightly rigid, robust but pliable sheet that holds it shape once bent. Not a lot to ask!

Anybody done anything similar and could advise?

Cheers
