摘要
为改善玻璃纤维增强聚苯硫醚(PPS)复合板材的力学性能,分别以柔性的玻璃纤维布和PPS非织造布作为增强体和基体,采用叠层热压成型法制备出刚性的复合板材,采用力学性能测试、XRD、PLM、SEM研究了热压温度、热压时间、玻璃纤维含量和处理玻璃纤维布的硅烷偶联剂种类对复合板材的力学性能、结晶度、结晶形态和微观形貌的影响。结果表明,在无硅烷偶联剂处理玻璃纤维布时,控制热压温度为320℃,热压时间为30min,压力为30MPa,玻璃纤维质量分数为50%,复合板材的拉伸强度和弯曲强度最佳,分别为286.0MPa和175.0MPa,缺口冲击强度达到61.6MPa。使用硅烷偶联剂KH560处理玻璃纤维布,在最佳成型工艺条件下,复合板材力学性能改善最明显,其弯曲强度为394.9 MPa,弯曲模量为23.6GPa,层间剪切强度为16.4MPa,缺口冲击强度为81.0MPa。通过优化实验条件和使用硅烷偶联剂处理玻璃纤维表面,复合板材的力学性能得到了明显提高。
To improve the mechanical properties of glass fiber reinforced polyphenylene sulfide(PPS)composite laminate,the rigid composite laminate was prepared by thermo-compression lamination using the flexible glass fiber cloth and PPS nonwovens as reinforcement and matrix.Using the mechanical test,XRD,PLM and SEM,the effects of hot pressing temperature and time,content of glass fiber and silane coupling agents on the mechanical properties,crystallinity and microstructure of the composite laminates were explored.The results show that the tensile strength,flexural strength and notched impact strength of the composite laminate with 50 wt% glass fiber cloth are 286.0 MPa,175.0 MPa and 61.6 MPa,respectively,where the composite laminate is hot-pressed at a temperature of 320℃for 30 min under a pressure of 30 MPa.It is found that using the silane coupling agent KH560 can significantly improve the mechanical properties of composite laminates.The flexural strength reaches to 394.9 MPa and the flexural modulus reaches to 23.6 GPa.Meanwhile,the inter laminar shear strength and notched impact strength are16.4 MPa and 81.0 MPa,respectively.The mechanical properties of composite laminate have been greatly improved by optimizing the experimental conditions and using the silane coupling agent to treat the surface of glass fiber.
