以第3代环氧端基脂肪族超支化聚酯(EHBP)增韧的环氧树脂(E-51)为基体材料,超支化聚酯基二茂铁(HBPE-Fc)为吸波剂,制备具有一定力学承载及电磁性能的超支化聚酯基二茂铁/环氧树脂(HBPE-Fc/E-51)复合材料,并通过力学性能测试及扫描电镜、矢量网络分析仪等研究了该复合材料的力学及电磁性能.结果表明,添加较低含量的H BPE-Fc能较好地改善环氧树脂体系的拉伸及冲击性能,第4代HBPE-Fc质量分数为2％时,与纯环氧树脂体系相比,HBPE-Fc/E-51复合材料的拉伸强度、断裂伸长率和冲击强度分别提高了21.81％、34.32％和15.41％,对固化体系的拉伸断面分析发现引入HBPE-Fc后材料表现出韧性断裂.HBPE-Fc/E-51复合材料的玻璃化转变温度在105.29～130.27℃之间,具有良好的热稳定性,同时该复合材料具有一定的电磁特性.
