所谓的高功能性纤维一般是指纤维的力学性能具有强度>18cN/dtex,模量>445cN/dtex的特种纤维。有时也称高强度、高模量、低伸度、耐高温、耐冲击、耐化学性的纤维为高功能性纤维。目前,全世界开发中和工业化生产的高功能性纤维主要有:对位芳香族纤维1414、间位芳香族纤维1313、聚苯并噁唑纤维和以碳纤维为主的无机纤维。自上个世纪的60年代末和70年代初,芳香族纤维1313和芳香族纤维1414在美国首先工业化
So-called high-functional fibers generally refer to the mechanical properties of fibers with special fibers having an intensity> 18 cN / dtex and a modulus> 445 cN / dtex. Sometimes also called high strength, high modulus, low elongation, high temperature, impact resistance, chemical resistance of the fiber is highly functional fibers. At present, the world’s development and industrial production of high-functional fibers are: para-aromatic fibers 1414, meta-aromatic fibers 1313, polybenzoxazole and carbon fiber-based inorganic fibers. Since the late 1960s and early 1970s, aromatic fibers 1313 and aromatic fibers 1414 have been first industrialized in the United States
