采用一种结构与超高分子量聚乙烯(UHMWPE)纤维相似、且对纤维表面具有良好浸润性的碳氢树脂(PCH)作基体,通过层压成型方法制得UHMWPE/PCH复合材料.研究了复合材料的力学性能、介电性能、吸湿性能及界面黏结性能.结果表明,UHMWPE/PCH复合材料介电性能优异、力学性能好、耐湿热性能较佳、界面黏结性能好,可用作高性能透微波复合材料.
Hydrocarbon resin (PCH) with good wettability with the ultra high molecular weight polyethylene (UHMWPE) fiber surface was selected as the matrix,which is similar to UHMWPE fiber in structure.The UHMWPE/PCH composite material was manufactured by hot press molding.The mechanical properties,dielectric properties,water absorption,hydrothermal property and interfacial bond property were characterized.The results indicate that the UHMWPE/PCH composite possesses good mechanical properties,excellent dielectric properties,low water absorption,excellent hygrothermal properties and interfacial bond property.
