[Abstract]:Starting with the microstructure, chemical composition and mechanical properties of plant fiber, the paper aims at the interfacial properties of plant fiber reinforced composites. This paper summarizes the research progress of improving the mechanical properties of composites by using vegetable fiber surface treatment method at home and abroad, analyzes the bottlenecks encountered, and proceeds further from the point of view of structural design of composite materials. Taking full advantage of the unique multi-level and multi-scale microstructural characteristics of plant fiber, the mechanism of mechanical damage and destruction of multi-level and multi-scale interface of plant fiber reinforced composite is revealed. The interfacial control and mechanical properties of plant fiber reinforced composites are realized. On this basis, the structural design principle and the unique interfacial mechanics research method of plant fiber reinforced composites are proposed, which take into account the flame retardancy and acoustic properties. In addition, the application of related basic research results in aviation, rail transit and other fields is also introduced, and the future research direction is put forward to realize the application of structure and function integration of green composite materials.
