Carbon—;fibre—;based composite manufacturing processes have been considered for automotive body panel applications. A full—;scale front wing—fender component was produced using two composite manufacturing processes (a semi—;impregnated (semi—;preg) system and a novel directed fibre preforming—resin transfer moulding process) and compared with an existing stamped steel component for mechanical properties, weight saving, and cost, using a technical—;cost—;modelling procedure. Mechanical testing demonstrates that the carbon fibre composite solutions can provide 40—50 per cent weight saving for an equivalent bending stiffness to steel panels and greatly improved dent resistance. For the part studied, carbon fibre semi—;preg systems offered the lowest cost process up to around 500 parts/annum and directed fibre preforming technologies were cheaper between 500 and 9000 parts/annum. The steel component was seen to be more cost effective at volumes above around 9000 parts/annum.
