摘　　要：通过Digimat软件对玄武岩纤维增强聚丙烯(BF/PP)复合材料进行代表性体积单元(RVE)建模,研究纤维含量、纤维长径比和纤维取向对复合材料力学性能的影响。模拟结果表明,玄武岩纤维质量分数为5%、10%、20%和30%的BF/PP复合材料相较于基体材料的弹性模量分别提升16.43%、79.08%、214.03%和406.01%,玄武岩纤维长径比大于200对BF/PP复合材料的弹性模量影响较小,BF/PP复合材料的弹性模量随着玄武岩纤维取向偏离载荷方向程度的变大而降低。实验结果表明,玄武岩纤维质量分数从5%增至30%,BF/PP复合材料的弹性模量提升38%,实验结果与模拟实验的结果误差为128.7%。Digimat软件对玄武岩纤维含量对BF/PP复合材料的力学性能影响预测趋势较为精确,可为实际生产提供参考。The representative volume element(RVE)modeling of basalt fiber reinforced polypropylene composites(BF/PP)was carried out by Digimat software.The effects of fiber content,fiber aspect ratio and fiber orientation on mechanical properties of the composites were analyzed.The simulation results showed that the elastic modulus of BF/PP composites with basalt fiber mass fraction of 5%,10%,20%and 30%compared to the matrix material was increased by 16.43%,79.08%,214.03%and 406.01%,respectively.The effect of basalt fiber aspect ratio greater than 200 on the elastic modulus of BF/PP composites was relatively small.The elastic modulus of BF/PP composites decreased with the increase of basalt fiber orientation deviating from the load direction.The experiment results showed that the elastic modulus of BF/PP composites increased by 38%when the basalt fiber content increased from 5%to 30%.The error between the experimental results and the simulation results was 128.7%.The Digimat software accurately predicted the influence of different contents of basalt fibers on the mechanical properties of BF/PP composites,providing a reference for actual production.
