摘要
综述耐高温热固性聚酰亚胺树脂及复合材料的研究进展。经过近四十年的发展,形成了多种封端剂封端的热固性聚酰亚胺树脂,其中主要是降冰片烯和4-苯乙炔基苯酐封端聚酰亚胺,长期使用温度涵盖280~450℃的聚酰亚胺树脂及其复合材料体系。低成本、高韧性和有机无机杂化聚酰亚胺树脂基复合材料将是聚酰亚胺复合材料发展的主要方向。
Advance in thermosetting polyimide and its composites were reviewed. In the last forty years, many kinds of endcap reagent were fund to synthesis polyimide resin matrix for composites, and most of polyimide was endcaped by Nadic anhydride or PEPA an- hydride. Many series of polyimide resin were developed to the service in 280-450℃ for aeroengine. Low-cost polyimide, high tough- ness polyimide and organic/inorganic hybrid polyimide will be the main directions of polyimide study in the future.
