摘要: 研究了聚酰胺66(PA66)改性玻璃纤维(GF)增强聚苯硫醚(PPS)(PPS/PA66/GF)复合体系的摩擦因数、磨损体积、磨损后表面的微观形貌及损耗因子峰值、储能模量对摩擦因数的影响。结果表明,PA66的加入显著改善了复合材料的摩擦学性能,当PA66含量为40 %(质量分数,下同)时,磨损最小,为5.24 mm3,相对于PPS+30 %GF(13.60 mm3)下降了61 %;扫描电镜分析磨损表面,随着PA66含量的增加,磨损机理由磨粒磨损转为粘着磨损;复合材料损耗因子峰值越大,摩擦因数越小;初始储能模量越大,摩擦因数越小。

Abstract: The effect of polyamide 66(PA66)on the tribological properties of glass fiber(GF)-reinforced polyphenylene sulfide(PPS) composites was studied. The inclusion of PA66 decreased the friction coefficients of PPS composites. When PA66 content was 40 wt%, the wear rate of the composites decreased from 13.60 to 5.24 mm3. The morphology of wear surface was investigated using SEM. It revealed that wear mechanisms of composites transformed from abrasive into adhesive wear with PA66 introduced. PA66 formed a non-uniform and discontinuous adhesive transfer film on steel counterface, while PPS did not. The maximum of the tangent of phase shift (tan δ) and storage modulus(E’) could be related with friction coefficients. The higher the (tan δ) maximum and E’, the smaller the friction coefficient smaller.
