研究加入不同固化剂T31和JA-1后对环氧树脂(EP)/四针状氧化锌晶须(T-ZnOw)复合材料性能的影响。测试了复合材料的拉伸强度、缺口冲击强度、导热性能和介电强度。结果表明，JA-1固化体系的力学性能和介电强度比T31固化体系更优越。当T-ZnOw含量为5份时，加入JA-1及T31固化剂时EP/T-ZnOw复合材料的拉伸强度最大值分别是31.4 MPa和27.6 MPa；加入JA-1固化剂时,当T-ZnOw含量为3份时EP/T-ZnOw复合材料的缺口冲击强度最高达到29.5 kJ/m2，加入T31固化剂的复合材料的缺口冲击强度基本在10 kJ/m2以内；当T-ZnOw含量为5份时加入JA-1和T31固化剂后复合材料的介电强度分别比纯EP增加了116%和106.7%。复合材料中加入T31固化剂后的导热性能要比JA-1固化剂的稍好。

The properties of epoxy resin(EP)/tetrapod-like zinc oxide whiskers(T-ZnOw) composites using different curing agents(T31 and JA-1) were investigated . The tensile strength , notch impact strength, thermal conductivity and dielectric strength were tested. The results show that mechanical performance and dielectric strength of the systems using JA-1 as curing agent are more superior than the systems adding T31 as curing agent. When T-ZnOw content is 5 phr, adding JA-1 and T31 curing agent, the maximum value of tensile strength of the composites is 31.4 MPa and 27.6 MPa respectively. When the content of T-ZnOw is 3 phr,the maximum value of notch impact strength is 29.5 kJ/m2 for the composite adding JA-1 as curing agent, however the impact strengths of the composite using T31 as curing agent are mainly less than 10 kJ/m2. When the content of T-ZnOw is 5 phr, the values of dielectric strength for the compostes using JA-1 and T31 as curing agents increases 116%and 106.7%respectively than pure EP. The heat-conducting property of the composite using T31 as curing agent is a bit better than that of the composite adding JA-1 as curing agent.
