摘要
将碳纤维与热致液晶高分子(TLCP)经成型加工制得样条,24 h后测试样条的表面电阻率、熔点、结晶度,并考察碳纤维的加入对液晶高分子力学性能的影响。结果表明:TLCP表面电阻率随碳纤维含量的增加而下降,当碳纤维含量达到20%时,材料的表面电阻率最低,抗静电效果最佳;碳纤维的加入使结晶度稍有提高,拉伸强度提高明显,但是TLCP的冲击强度有所降低。
Antistatic thermotropic liquid crystal polymer (TLCP) was prepared by blending different content of carbon fiber (CB) with TLCP resin. The surface resistivity, melting point, degree of crystallinity and mechanical property were characterized after 24 hours. The results show that the surface resistivity of CB/TLCP blends decrease with the increasing of CB content, and the surface resistivity performance obtains when CB is up to 20%. Degree of crystallinity and tensile strength increase while impact strength decreases in different degrees.
