碳纤维基复合材料制造工艺已被考虑用于汽车车身面板应用。一个完整的-;使用两种复合材料制造工艺（半浸渍（semi-preg）系统和新型定向纤维预成型-树脂传递模塑工艺）生产了比例前翼子板部件，并使用技术-成本-建模程序将其与现有冲压钢部件的机械性能、重量减轻和成本进行了比较。机械测试表明，碳纤维复合材料解决方案可以提供40- 50%的重量节省相当于钢板的弯曲刚度，并大大提高抗凹陷性。对于所研究的部件，碳纤维半预浸料系统提供了最低成本的工艺，高达约500件/年，定向纤维预成型技术的成本在500至9000件/年之间。钢组件被认为是更具有成本效益的产量超过约9000件/年。
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.
