摘　　要：为研究平纹增强热塑性复合材料耐流体介质的老化行为,采用热模压工艺制备玻璃纤维和碳纤维平纹织物增强聚苯硫醚(PPS)复合材料,不同角度铺贴后热模压工艺进行成型。选取水、液压油、磷酸酯液压油/水混合液、燃油、丁酮5种液体,将复合材料分别在高温或常温下浸泡至饱和状态。结合大气环境构建交通运输领域常见的9种老化使用环境,以ASTM短梁剪切标准和面内剪切标准为依据,开展复合材料层间和面内剪切试验,评估其老化后性能衰退情况。结果显示,高温高湿环境对PPS复合材料层间和面内剪切性能均有明显的衰减作用,玻纤复材性能下降超50%,碳纤复材性能下降30%。液体介质浸透后,水对复合材料的强度影响最大,液压油、燃油和丁酮影响均较小,常温测试层间和面内剪切性能下降约10%。最后,老化机理分析可为热塑性复材应用场景开发提供数据参考。To investigate the aging behavior of plain weave reinforced thermoplastic composites in fluid media,glass fiber and carbon fiber plain weave fabric reinforced polyphenylene sulfide(PPS)composites were prepared by the hot molding process.After laying at different angles,the composites were molded by the hot molding process.Five liquids,namely water,hydraulic oil,phosphate ester hydraulic oil/water mixture,fuel,and butanone,were selected.The composites were immersed in each liquid at high temperature or room temperature until saturation.Nine common aging service environments in the transportation field were constructed in combination with the atmospheric environment.Based on the ASTM short beam shear standard and in-plane shear standard,the interlaminar and in-plane shear tests of the composites were carried out to evaluate the performance degradation after aging.The results show that the high-temperature and high-humidity environment has a significant attenuation effect on the interlaminar and in-plane shear properties of PPS composites.The performance of glass fiber composites decreases by more than 50%,and that of carbon fiber composites decreases by 30%.After the liquid medium permeates,water has the greatest influence on the strength of the composites,while the influences of hydraulic oil,fuel,and butanone are relatively small.The interlaminar and in-plane shear properties decrease by about 10%in the room temperature test.Finally,the analysis of the aging mechanism can provide data reference for the development of application scenarios of thermoplastic composites.
