Study on performance of PPS/PA66/GF/HGM quaternary composites
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.
