摘　　要：以天然橡胶(NR)为基体,玄武岩纤维(BF)为增强体,制备了玄武岩纤维-天然橡胶(BF/NR)复合材料,研究分析了玄武岩纤维的长度及取向方向对BF/NR复合材料的硫化性能、基本物理性能、动态力学性能的影响。实验结果表明:在玄武岩纤维取向方向相同的情况下,BF/NR复合材料的综合性能随纤维长度的增加先增加后降低,当玄武岩纤维长度为6 mm时,BF/NR复合材料的性能最佳;在纤维长度相同的情况下,经轴向取向制得的BF/NR复合材料性能最佳,与无纤维的胶料相比,经轴向取向制得的6 mm BF/NR复合材料其拉伸强度提高了10.85%,撕裂强度提高了17.78%。通过扫描电镜(SEM)测试发现,玄武岩纤维与橡胶基体的界面结合性较好,并且在橡胶基体中的取向状态及分散情况较为良好,因而发挥了玄武岩纤维的增强作用。In this paper, basalt fiber/natural rubber(BF/NR) composites were prepared with natural rubber(NR) as matrix and basalt fiber(BF) as reinforcement. The influences of the length and orientation of BF on the vulcanization property, basic physical properties and dynamic mechanical properties of BF/NR composites were researched and analyzed. The experimental results showed that the composite properties of BF/NR composites would increase first and then decrease with the increase of the fiber length when BF got same orientation direction, and BF length was 6 mm, the properties of BF/NR composites were best. When fiber length were same, the properties of BF/NR composites prepared by axial orientation were best. Comparing the vulcanized rubber without BF, the tensile strength and tear strength of 6 mm BF/NR composites prepared by axial orientation increased about 10.85% and 17.78%. Through scanning electron microscopy(SEM) testing, it was found that the BF had better interface bonding with rubber matrix, and better orientation and dispersion in rubber matrix, therefore, the BF reinforced the BF/NR composites.
