The fiber sharing coefficient and the clustering fiber content are adopted to characterize the clustering effect of the basalt fiber in the epoxy resin, and to establish the micromechanics model and the geometry model of the clustering fiber. Meanwhile, the tensile strength of the BFRP is numerically calculated and compared.The results show that, when the fiber volume fraction is fixed, the BFRP tensile strength is decreased with the increase of the fiber orientation angle, and when the fiber orientation angle is fixed, the BFRP tensile strength is increased with the increase of the fiber volume fraction. The fiber sharing coefficient is decreased with the increase of the fiber vol-ume fraction, and the clustering fiber content is increased with the increase of the fiber volume fraction. The fiber clustering effect increases the BFRP critical fiber volume fraction as compared with the sharing one, and decreases the enhancement amplitude of the tensile strength of the basalt fiver in the epoxy resin substrate. The calculated values of the BFRP tensile strength with consideration of the fiber clustering effect are close to the experimental results., authors=HE Jingjing, SHI Junping, authorsList=HE Jingjing,

articleAbstract=基于Tsai理论，针对纤维体积掺加率为0.6%、0.9%、1.2%、1.5%，纤维取向角为0°、15°、30°、45°的玄武岩纤维-环氧树脂复合材料（BFRP）进行了轴向拉伸强度实验研究，并引入纤维均分系数和打团纤维含量表征玄武岩纤维在环氧树脂中的打团效应，建立打团纤维的细观力学模型与几何模型，对BFRP的拉伸强度进行了数值计算对比分析。结果表明，纤维体积掺加率一定时，BFRP的拉伸强度随纤维取向角的增大而减小，纤维取向角一定时，BFRP的拉伸强度随纤维体积掺加率的增大而增大；纤维均分系数随纤维体积掺加率的增大而减小，打团纤维含量随纤维体积掺加率的增大而增大；纤维打团效应的存在，导致了BFRP的纤维临界体积掺加率较纤维均分时有所增大，降低了玄武岩纤维对环氧树脂基材拉伸强度的增强幅度；考虑纤维打团效应的BFRP拉伸强度计算值与实验结果接近。,
