摘要

以环氧树脂(EP)和聚氨酯(PU)为聚合物基体，短切玄武岩纤维(BF)为增强剂，制备了BF/EP-PU复合材料。研究了不同掺量的短切高炉对BF/EP-PU复合材料性能的影响。SEM照片结果表明，BF与聚合物基体形成的连接和切割BF对BF/EP-PU复合材料起补强作用。当玄武岩纤维掺量为3wt%时，复合材料的力学性能得到了发展，抗剪强度达到18.5MPa，击穿场为16.6kV/mm。

Study on properties of BF/EP-PU composite

Epoxy resin (EP) and polyurethane (PU) were used as polymer matrix, chopped basalt fiber (BF) as reinforcement and prepared BF/EP-PU composites. And studied how different content of chopped BF influenced on the properties of BF/EP-PU composite. The results of SEM photos showed that the connection of BF and polymer matrix formed and chopped BF played a reinforcing role in BF/EP-PU composite. Mechanical properties of composites have attained to develop, shear strength reached 18.5MPa and breakdown field was 16.6kV/mm, when the chopped basalt fiber content was 3wt%.
