Kevlar/aramid introduction 发布时间:2017-08-21 14:48:05
The full name of Kevlar/aramid is P-Phenlene terephthalamide, it also called“para-ramid fiber”, is   is a new type of aramid fiber composite material(aramid 1414).It has a series of excellent properties,such as high strength, high modulus, high temperature resistant, acid and alkali resistant, low weight, good insulation and aging resistant. The intensity is 5 to 6 times compared with steel wire, 2 to 3 times of modulus,and twice when it comes to toughness. The weight is only about 1/5 of wire,and that it does not decomposed and melting at the temperature of 560 degrees. The discovery of aramid fiber material is considered to be a very important historical process.
