Long Fiber Reinforced Thermoplastic (LFT) is a lightweight, high-strength, and easy-to-recycle new vehicle composite material, has good mechanical properties, heat resistance, weather which found increasing application in automobile industry. It of importance to understand the relationship between micro phase, macro-mechanical properties structural performance components. This article evaluates LFT from level material The were numerically theoretically predicted provide instruction for next choice. Two typical components, namely, car seat frame bumper beam, selected evaluate LGF/PP compared with other competing materials terms cost. In case same volume, 40% LECT/PP lighter cheaper, conducive energy saving emission reduction. was shown that LECT/PA66 beam had higher absorption ratio, weight, specific absorption, advantageous promising candidate existing components its fulfilling requirements.
