- Light weighting is an effective strategy in increasing energy efficiency in the automotive industry. In this paper, mass reduction with cost benefit was targeted in an exterior trim panel. Modified polypropylene copolymer (PPCP) material was developed for an exterior trim large panel (1400 X 700mm) with integrated grill mesh. The part had challenging requirements in terms of slow speed impact, structural durability, dimensional stability, aesthetics, thermal ageing resistance, cold impact resistance, scratch resistance and weathering resistance. The compounded PPCP material met these requirements by having ultra-flow behaviour, optimum tensile strength, modulus, impact strength and thermal properties. The combination of material, optimized part and tool design led to weight savings and considerable cost reduction.
