【摘要】 研究了含二氮杂萘酮结构环氧端基聚芳醚酮 (E- PPEK) / E- 44/ DDM环氧树脂复合体系的微观结构和热 -力学性能。分析了 E- PPEK在环氧树脂基体中的增韧机理。E- PPEK/环氧树脂体系为均相结构。加入一定量的 E- PPEK可大幅度提高环氧树脂的韧性 ,而不降低环氧树脂的模量和耐热性更多还原

【Abstract】 The microstructure and thermo mechanical properties of epoxy terminated polyether ketone (E PPEK)/epoxy resin composite systems were investigated, and the toughing mechanism of E PPEK in epoxy resin was discussed. The E PPEK/epoxy resin systems are simple phase structure. The toughing of epoxy resin was appreciably enhanced by adding some E PPEK, in the meaning, the tensile modulus and glass transition temperature ( T g) of epoxy resin are not decreased but increased. The toughing effect comes mainly from the IPN of E PPEK/epoxy systems.更多还原
