摘要
采用热压罐成型的方法制备了石英纤维布/J-284PD氰酸酯复合材料,并验证了其力学性能、介电性能和耐湿热性能。结果表明:中温固化的石英纤维布/J-284PD复合材料,其介电性能、力学性能和耐湿热性能优异,其中拉伸强度为630 MPa,层间剪切强度为58.8 MPa,介电常数为3.1,损耗角正切为0.003;经过10 d湿热试验后,性能最大仅下降10%。
Quartz fiber cloth/J-284 PD cyanate ester resin composites were prepared by hot-pressing tank forming method,and their mechanical properties,dielectric properties and moisture-heat resistance were verified.The results show that quartz fiber cloth/J-284 PD cured at medium temperature composites materials have excellent mechanical,dielectric properties and moisture-heat resistance.Among them,the tensile strength is 630 MPa,the interlaminar shear strength is 58.8 MPa,the dielectric constant is 3.1,and the dielectric loss is 0.003.After 10 days of moisture-heat test,the maximum performance decline is only 10%.
