二氨基二苯醚型聚酰亚胺材料阻尼性能及研究进展

Progress and damping properties on 4,4′-oxydianiline typepolyimide material

有机高分子材料聚酰亚胺是耐高温的航空航天材料,且其隔热性可保护不耐高温的材料在高温环境下不被破坏,其应用已成为航空航天新复合材料领域的研究热点。综述了近年来不同结构聚酰亚胺(PI)的动态力学性能的研究进展,重点介绍了含二氨基二苯醚(ODA)结构的聚酰亚胺,指出并说明了聚酰亚胺作为阻尼材料应用的可能性。

Polyimide （P]）, a organi,＇ polymer material is a kind of heat resistance aerospace materials, its heat insulation property can protect materials that are no-resistant to high tempreture /tom damage in the high temperature environment. Its application have become hotspots in the field of new aerospace composite materials. Research progress of dynamic mechanical property of polyimide with different structures has been reviewed and the 4, 4＇-oxydianiline （ODA） type polyimide is mainly introduced in this paper. The possibility of applying potyimide as damping materials has been discussed as well.
