Abstract:: Hemp fibers thermoplastic composites have the characteristics of light weight, environmental protection and impact resistance. It is a material with great added value and potential, and has become a hot spot in the research of fiber composites. In the traditional production process of hemp fibers composites, there are problems such as uneven fiber dispersion and large amounts of volatile organic compound (VOC) emitted, which restrict the application of hemp fibers composites. In this research, a material preparation method of fiber solid-phase blending was created, a surface treatment technology to improve the interface mechanical properties of hemp fibers composites was developed, and a key technology for preparation of hemp fibers composites was developed to form the industrialization of hemp fibers thermoplastic composites. The products are widely used in the fields of automobiles, high-speed rail, ships and building materials. This research has achieved significant economic and social benefit in promoting the development of lightweight materials, improving the comprehensive utilization of renewable resources of hemp fibers, and promoting the technological progress in the national industrial textile industry
