　　采用等离子体改性技术对玄武岩纤维进行表面改性处理，通过SEM对改性后的纤维表面形貌进行表征，研究真空度、处理时间和功率对玄武岩／聚丙烯复合材料力学性能的影响，从而确定最佳处理工艺，并研究等离子体处理对复合材料结晶性能的影响。结果表明：纤维经等离子体处理后，等离子体对纤维表面产生刻蚀作用，使纤维表面变得粗糙；当真空度、处理时间和功率分别为20 Pa、5 min、100 W时，复合材料的力学性能最佳，此时拉伸强度为247 MPa，抗弯强度为49．319 MPa；改性处理能促进聚丙烯的异向成核，使其结晶度增加。

The surface modification of basalt fiber using the plasma treatment was studied .The surface physical characterization of basalt fiber was conducted by using scanning electron microscope (SEM).To determine the best treatment process, the effects of vacuum degree, processing time and power on the basalt/polyproplene composites were studied .The influence of plasma treatment on the crystallization property of composites was also studied.The results show that the plasma treatment can increase surface roughness of the basalt fiber surface.The samples gain the best mechanical properties (the tensile strength is 247 MPa, the bending strength is 49.319 MPa) when the vacuum degree,processing time and power are secleted as 20 Pa, 5 min, and 100 W.And modification treatment can accelerate the anisotropic nucleation of polypropylene and increase the degree of crystallinity .
