A Light-Weight Bumper System Utilizing Azdel® Glass Fiber Reinforced Thermoplastic Laminate 800817

ABSTRACT

Automotive design efforts to resolve the conflict imposed by Federal regulations governing Corporate Average Fuel Economy (CAFE) and the inherent weight penalty of FMVSS-215 Bumper Standards have centered around lightweight material substitutions, most notably HSLA steels and aluminum. Recent developments in non-metallic structures are directed at further reduction in the weight penalties of steel and the cost penalties of aluminum. This study presents the investigation of a continuous glass fiber reinforced thermoplastic in a light-weight, energy-absorbing bumper system through its design, fabrication and successful prototype testing. Material properties, design parameters, molding process and vehicle impact testing will be reviewed.
