解读聚乙烯纤维的展及运用 高功用聚乙烯纤维作为新式有机纤维，其功用与复合资料的运用是科研人员研讨的热门之一。侧重探求高功用聚乙烯纤维的功用、外表改性以及复合资料的运用等难题。　　 High-performance polyethylene fiber as a new type of organic fiber, its performance and application of composite materials is one of the hot topics in the study of scientific research personnel. Mainly to explore the performance of high-performance polyethylene fiber, surface modification and application of composite materials, etc. 　　近几年，纤维的高功用、高功用和高理性一直是研讨者对新式化纤资料研讨的要点，高功用聚乙烯纤维是继碳纤维、芳纶之后具有极其重要战略意义的新式纤维资料，因其共同的功用，该纤维及其增强复合资料已被广泛运用于多个范畴，倍受研讨人员与出产公司的喜爱。　 In recent years, fiber of high performance, high function and high perceptual researchers has been the focus of the research of new type fiber materials, high performance PE fiber is after carbon fiber, aramid fiber, has the extremely important strategic significance of the new fiber material, because of its unique properties, the fiber and its composites have been widely used in many fields, destinations for researchers and manufacturers. 　1 高功用聚乙烯纤维的布局及特色　 1, structure and characteristics of high-performance polyethylene fiber 　高功用聚乙烯纤维的高强高模特性来源于本身的超高相对分子质量、沿轴向高度取向和晶体布局。聚乙烯具有亚甲基相连的大分子链的化学布局，在超倍牵伸时，构成伸直链超分子布局，高功用聚乙烯纤维的优胜功用完全是因为它的这种超分子布局决议的。　 High-performance polyethylene fiber with high strength and high property from its height of ultrahigh relative molecular mass, along the axial orientation and the crystal structure. Polyethylene with methylene is connected to the chemical structure of macromolecular chain, in times when drafting form straight-chain supramolecular structure, better performance of high-performance polyethylene fiber completely because it is the super molecular structure. 　高功用聚乙烯纤维的一个杰出长处是密度低，为0.97g/cm3，使得其质量轻的一起，可以到达较大的比拉伸强度和拉伸模量；因为聚乙烯不含易与触摸物质发作反响的羟基、芳香环等基团，使得其具有高耐酸碱腐蚀性；一起，高功用聚乙烯纤维熔点比一般聚乙烯低，沸水缩短率也较低。别的，即便在很低的温度下，该纤维仍可以坚持柔软。　 A prominent advantage of high-performance polyethylene fiber is low density, 0.97 g/cm3, makes the quality of light at the same time, can be larger than the tensil
