Hi,

All thicknesses of carbon fibre sheet will have a degree of 'bendability', the main influence being the thickness. If you went with a 1mm wet-lay sheet you would find it very easy to bend round the size of radious that you'll find inside a wheel arch but if you went up to a 3mm pre-preg then you'd find it almost impossible to bend at all.

If this is just a structural exercise (i.e. not cosmetic) and you really want to add some sturdy protection to the inside of the fenders then how about laminating some 175g kevlar cloth with epoxy resin. It would be quick and easy to do and would have incredible resistance to wear; far better than carbon fibre sheet would. Also, you would have no concerns over it fitting around the contour - the dry material would be easy to laminate around any shape.

I hope this helps.

Best regards, Matt
