高性能热固性聚酰亚胺树脂研究进展

Thermosetting polyimide precursor has good solubility and low melt viscosity before cross-linking. It can be processed by injection, extrusion, resin transfer molding (RTM) or other methods. Thermosetting polyimide composites possess extremely excellent heat resistance and mechanical properties and are widely used in weapons, aerospace, automotive industry and other fields. This article systematically reviewed the research progress and development of thermosetting polyimide and its composite materials, and introduced the representative achievements of thermoset polyimide, and prospected the development of related research and its applications.
