摘要: 为了响应我国碳达峰和碳中和的环境目标,本文将生物质马来海松酸缩水甘油酯环氧树脂、石油基双酚A型环氧树脂E-54和固化剂DDS复配,研究高温固化松香基环氧树脂及其复合材料的热和力学性能。结果表明:固化后的环氧树脂具有较高的力学性能和热失重温度,配方DGE树脂固化后玻璃化转变温度为207 ℃,拉伸强度为87.3 MPa,拉伸模量为3.52 GPa,断裂伸长率为4.38%,5%热分解温度约为297 ℃;以DGE/CCF300预浸料制备的复合材料层合板干态玻璃化转变温度为207 ℃,湿态玻璃化转变温度为170 ℃,干态湿态力学性能与已经应用于飞机结构件的基于5222/HT3复合材料性能相当。

Abstract: In response to the environmental goal of carbon peaking and carbon neutralization in China, biomass glycidyl esters maleopimaric acid epoxy resin, petroleum based bisphenol A epoxy resin E-54 and curing agent DDS were compounded to study the thermal and mechanical properties of high temperature cured rosin based epoxy resin and its composites. The results show that the cured epoxy resin has high mechanical properties and thermogravimetric temperature. The glass transition temperature of the cured DGE resin is 207 ℃, the tensile strength is 87.3 MPa, the tensile modulus is 3.52 GPa, the elongation at break is 4.38%, and the 5% thermal decomposition temperature is about 297 ℃. The dry glass transition temperature of composite laminates prepared with DGE/CCF300 prepreg is 207 ℃, and the wet glass transition temperature is 170 ℃. The dry and wet mechanical properties are equivalent to those of 5222/HT3 composites which have been applied to aircraft structures.
