Teijin Develops Extra-Light Automotive Side-Door Module Made of Advanced Multi-Material Composites

摘要

Teijin Limited's automotive composites specialty groups have developed a multi-material composite automotive door concept that maintains required crash specifications while reducing overall weight by 35% when compared to a conventional steel door.The module is made from carbon fiber sheet molded compound(SMC),glass fiber SMC and unidirectional glass fiber reinforced plastics(GFRP)to offer both high strength and low weight.Additional benefits include cost efficiency equal to that of an aluminum door module,and the ability to achieve deep draws and superior design freedom not achievable with metal.The solution also withstands the heat level of the conventional E-coat automotive painting process.
