Problems solved by technology

[0002] In recent years, the number of cars in the world has been increasing day by day, and they are changing people's work and life with increasing influence. The rapid development of the automobile industry is facing three major problems: energy consumption, environmental protection and safety. It has become the focus of social attention. The existing polyurethane, polyvinyl chloride and chemical fiber reinforced automotive interior parts generally contain substances harmful to the human body, such as formaldehyde, benzene, toluene and other volatile organic compounds. On the other hand, When these chemical fiber interior parts burn, they will release a large amount of suffocating poisonous gas, which is the "first killer" in the event of an accidental fire in a car. Therefore, the development of the automobile industry has proposed high-quality, Requirements for lightweight, environmental protection, and safety. Research and development of high-performance environmentally friendly new interior materials has become an important direction in the field of new materials and interior product research. Environmentally friendly new interior materials based on biomass materials include pure biomass materials and ecological composites. Materials, used for seats, dashboards, interior and exterior decorative panels and fabrics, can achieve the comfort, aesthetics, non-toxic and odor-free of automotive interior parts, and have good energy absorption and impact resistance, but Its aging resistance and wear resistance cannot meet the requirements of use. At the same time, plant fibers have greater hygroscopicity, poor adhesion to the base resin, and low impact strength. Compared with chemical synthetic fibers, plant fibers have Microstructural defects and impurities seriously affect the combination of fibers and vertical interfaces, thereby affecting the overall mechanical properties of composite materials. Therefore, further improvements are needed on this basis
