以环氧树脂和聚氨酯为基体，短切玄武岩纤维（BF）为增强体，氢氧化铝为填料，制备了玄武岩纤维环氧树脂团状模塑料（BF-BMC）。系统研究了玄武岩纤维与氢氧化铝的质量比对BF-BMC力学性能、介电性能和吸水率的影响。结果表明：当BF与Al2O3的质量比为15/45时，BF-BMC模压制品的综合性能最佳，冲击强度27 kJ/m2，拉伸强度32 MPa，弯曲强度173 MPa，介质损耗因数0.013，介电常数6.2，体积电阻3.2×1013Ω，电气强度13.4 MV/m，吸水率小于1%。
An epoxy resin bulk molding compounds(BF-BMC) was prepared using epoxy resin and poly-urethane as matrix, chopped basalt fiber as reinforcement and Al2O3 as filler. The effects of different mass ratio of BF and Al2O3 on the mechanical properties, dielectric properties and water absorption of the BF-BMC were studied systematically. The results show that when the mass ratio of BF and Al2O3 is 15/45, the BF-BMC molded product has optimum comprehensive properties with 27 kJ/m2 of impact strength, 32 MPa of tensile strength and 173 MPa of bending strength, 6.2 of dielectric constant(ε), 0.013 of dielectric loss(tanδ), 3.2 × 1013Ω of volume resistance and 13.4 MV/m of breakdown strength and lower than 1% of water absorption rate.
