电场诱导对不饱和聚酯树脂/炭纤维/纳米炭黑复合材料性能的影响
采用不饱和聚酯树脂(UPR)、导电炭纤维(CF)和纳米炭黑(CB)制备了一种复合材料,对比分析电场诱导对材料的电学性能和基本力学性能的影响。结果表明:在导电填料添加适量的情况下,采用0.3V/Fm的直流电场诱导可以提高复合材料的导电能力,并表现出一定程度的各向异性。其中CB的添加量为0.5phr时,复合材料的电场诱导效果最佳;CF添加量为3,6,9phr的复合材料在电场线轴向的体积电阻率分别降低了46.8%,29.0%,12.5%,在电场线法向的体积电阻率分别降低了28.6%,18.8%,8.3%。同时,电场诱导基本没有改变复合材料力学特征,复合材料的基本力学性能与常规成型基本保持一致。...

The electrical and basic mechanical properties of the composite with elec- tric field induced and conventional molding was compared and analyzed. The results showed that the conductivity of composite was anisotropic and could be enhanced when the filling amount was appro- priate with 0. 3V//,m direct current (DC) electric field induced. The best CB filling amount was 0. 5phr. At that time, the volume resistivity of composite with CF filling amount was 3,6,9phr re- duced 46.8% ,29.0%,12.5% at axial direction, and 28.6 |
