摘要
采用超高分子量聚乙烯(UHMWPE)纤维作增强材料,结构与UHMWPE纤维相似、且对纤维表面具有良好润湿性的全碳氢树脂(PCH)作基体,通过热压成型工艺制备UHMWPE/PCH复合材料,并通过扫描电镜、介电谱仪等方法对复合材料的力学性能、介电性能、吸水、湿热性能及界面粘接性能进行表征。结果表明,UHMWPE/PCH复合材料力学性能良好、介电性能优异、吸水率小、吸湿率低、粘接性能好。
In this paper, we chose ultrahigh molecular weight polyethylene （UHMWPE） fiber as reinforcement and pure hydrocarbon （PCH） resin with the structure similar to the nonpolar UHMWPE fiber and a good wettability to the fiber surface as matrix. The UHMWPE/PCH composite material was manufactured by hot press molding. The mechanical properties, dielectric properties, water absorption, hygroseopicity and interracial adhesion were characterized by SEM, dielectric spectrometer and so on. The results show that UHMWPE/PCH composite possesses better mechanical properties, excellent dielectric properties, low water absorption, low hygroscopicity and good adhesion.
