Abstract:A kind of polyimide based composite aeroengine adjustment sheet was preparedꎬ modeling analyzed
and tested. The polyimide resin and its composite performances were studied by DMA and TGAꎬ as well as rheological
and mechanical testing machine. The results show that KH308 resin has excellent processing propertyꎻ the Tg tested by
DMA is 335℃ꎬ T5d
is 468.8℃ꎻ the MT300/ KH308 composite has pretty high temperature resistanceꎬ vibration resist ̄
ance and aging resistance. In additionꎬ instead of titanium alloy adjustment sheetꎬ the polyimide based composite
aeroengine adjustment sheet can achieve weight loss of 52% and the performances of polyimide based composite aero ̄
engine adjustment sheet can meet the design requirements.
