摘要
对发动机调节片用聚酰亚胺树脂及其复合材料性能、调节片力学仿真设计和装机试车考核三方面进行研究。采用DMA、TGA、流变仪和万能力学试验机等考察了KH308树脂及其复合材料性能,并结合ANSYS力学仿真计算等方法对复合材料调节片进行了结构设计。结果表明KH308树脂熔体最低黏度为14.8 Pa·s,具有良好的成型工艺性;T_g为335℃,T5d为468.8℃,MT300/KH308复合材料具有优良的耐热、抗振动及耐老化性能,可以有效替代钛合金调节片,实现减重52%,各项功能指标均满足设计要求。
A kind of polyimide based composite aeroengine adjustment sheet was prepared,modeling analyzed and tested. The polyimide resin and its composite performances were studied by DMA and TGA,as well as rheological and mechanical testing machine. The results show that KH308 resin has excellent processing property; the Tgtested by DMA is 335℃,T5 dis 468. 8℃; the MT300 / KH308 composite has pretty high temperature resistance,vibration resistance and aging resistance. In addition,instead of titanium alloy adjustment sheet,the polyimide based composite aeroengine adjustment sheet can achieve weight loss of 52% and the performances of polyimide based composite aeroengine adjustment sheet can meet the design requirements.
