Recently, automotive industry has been paying attention to vehicle weight reduction due to global trends toward reducing CO2 emission and fuel consumption. Lightweight materials, such as thermoplastic composites with high strength-to-weight and/or stiffness-to-weight ratio, are being rapidly applied to the interior and exterior components instead of metals or conventional low-to-medium strength plastics in vehicles. A continuous fiber reinforced thermoplastic composite (CFT) with excellent mechanical properties is one of the most promising thermoplastic composites for automotive applications, which can play the vital role in local reinforcing highly stresses regions of an automotive components. CFT with polypropylene and glass fiber is a typical material combination which is economically viable. In order to maximize the mechanical properties of CFT, fiber-matrix adhesion strength and degree of impregnation should be addressed in scientific manner. Also, manufacturing speed for CFT with reasonable degree of impregnation (or void contents) should be considered for commercialization in the cost-sensitive automotive industry. In this study, CFT was prepared by a new fiber-matrix adhesion approach which would increase the adhesion strength between the fiber and matrix through nano-scale wire growth on the fiber surface. The flow and impregnation behavior in the continuous impregnation process for CFT was investigated by impregnation model with Navier-Stokes equation and Darcy’s Law. Automotive applications such as rear bumper impact beams, rear seatback frames, battery carriers for EVs and tailgates will also be briefly overviewed to show CFT’s local reinforcing capabilities and weight reduction effects.
