摘要:
该文研制了碳化温度在600~900℃的聚丙烯腈(PAN)基低温碳化纤维,采用化学元素分析仪、广角X射线衍射仪和激光拉曼光谱仪分析了纤维的化学成分及微观结构,测试了纤维的力学及电学性能。结果表明:随着碳化温度的升高,纤维中碳元素质量分数提高,部分氮、氢、氧元素被去除;纤维线密度和断裂伸长率下降,体密度和拉伸强度上升;碳化过程中纤维内部乱层石墨结构体积分数提高,导致纤维体电阻率下降;低温碳化纤维/树脂复合涂层具有良好的防静电性能。
Abstract:
The polyacrylonitrile(PAN)-based fibers are carbonized at temperature of 600~900℃.Chemical composition and microstructure of the fibers are characterized using elemental analyzer,wide-angle X-ray diffractometer and laser Raman spectrometer.Mechanical and electrical properties of the fibers are examined.The results indicate that with the increase of the carbonization temperature,the mass fraction of carbon increases;nitrogen,hydrogen and oxygen are partially removed from the fibers;linear density and elongation at break of the fibers decrease,volume density and tensile strength of the fibers increase;electrical resistivity of the fibers decreases drastically due to the increasing volume fraction of turbostratic graphite structure formed in carbonization process;low-temperature carbonization fiber/resin composite coatings with admirable antistatic property can be prepared.
