ABSTRACT The automotive industry is faced with an unprecedented challenge, to produce lighter vehicles with less fuel consumption and pollution without sacrificing internal roominess and passenger safety. Therefore , new materials other than steel are being considered . This study presents the usage of composite materials instead of steel in certain parts (main rail, bumper, hood, fenders, wheel housing and doors) of the vehicle to improve its performance by studying of vehicle crashworthiness (frontal and offset impact). A finite element model of a 1994 Chevrolet C-1500 pick-up truck was modified and used for this purpose with the aid of the multi-purpose finite element code LS-DYNA . The results showed that, the usage of composite materials in vehicle frame (or all parts together) gives higher percentage of weight reduction and higher percentage of absorbed energy , than in the case of steel . | ||||
