以玻璃微珠(glass beads, GB)和玻璃纤维(glass fiber, GF)为增强填料,与聚酰胺(Polyamide, PA)1212粉末机械混合,采用选择性激光烧结(selective laser sintering, SLS)技术制备GB/GF/PA1212复合材料。用万能力学实验机和摩擦磨损实验机测试和分析GB/GF/PA1212复合材料的力学性能和摩擦磨损行为,研究GB含量对材料性能的影响。结果表明,添加适量GB填料可提高复合材料的拉伸性能和耐磨性能,尤其是能显著改善耐磨性能。其中,GB和GF质量分数分别为40%和10%时,复合材料的摩擦因数和磨损率最低,分别为0.23和1.1×10-3 mm3/(N·m)。
