摘　　要：为解决聚苯硫醚(PPS)质脆问题,进一步提升其轻量化应用水平,基于玻纤(GF)增强、聚酰胺66(PA66)增韧、空心玻璃微珠(HGM)减重的研究思路,采用熔融共混法制备了一系列HGM/GF/PA66/PPS四元复合材料,并对复合材料的微观结构、力学性能和摩擦学性能进行了系统研究。结果表明,加入少量PA66可显著提升PPS复合材料的韧性和水润滑性能,其力学强度无明显变化;加入HGM可大幅降低PPS复合材料的密度,并能有效提升复合材料的力学强度和摩擦学性能,但HGM含量过大会降低PPS复合材料的韧性;实验条件下,PA66、HGM的最佳含量分别为25%(质量分数,下同)和10%,此时复合材料具有最为优异的综合性能。To address the brittle nature of polyphenylene sulfide(PPS)and further reduce its density,a series of PPS/polyamide 66(PA66)/glass fiber(GF)/hollow glass beads(HGM)quaternary composites were prepared through melt blending with GF as a reinforcement,PA66 as a impact modifier,and HGM as a light-weight agent.The microstructure and mechanical and tribological properties of the composites were systematically investigated.The results indicated that the addition of a small amount of PA66 could significantly improve the toughness and water lubrication performance of the composites,and there was no change in their mechanical strength.The introduction of HGM significantly reduced the density of the PPS-based composites and effectively improved their mechanical strength and tribological properties.However,the excessive content of HGM resulted in a reduction in the toughness of the composites.The composites ob-tained the optimal performance at PA66 and HGM contents of 25 and 10 wt%,respectively.This study can provide a technical guidance for the development of lightweight and high-tough PPS composites and also extend the application range of PPS and its composites in high-end lightweight areas.
