Abstract Although the fiber reinforced thermoplastic plastics (FRTP) materials has been widely applied in the automotive industry for non-load-bearing or semi-load-bearing parts, they are hardly used in load-bearing parts due to higher performance requirements. This paper focuses on an integrated design method for automotive load-bearing parts by using assembled continuous-FRTP laminates and non-continuous-FRTP materials (referred to as AFRTP). First, aiming for the lightest weight, an integrate...

Abstract The mechanical performance of continuous large tow carbon fiber reinforced polyamide 6 laminates fabricated by hot press molding was studied using quasi-static and dynamic tests. The effects of layup, strain rate and high temperature were discussed. The results show that the thermoplastic composites possess strain rate strengthening effects and high temperature weakening dependence. Different layup laminates exhibit different sensitivities. The elastic modulus difference of unidirection...
