PAN基碳纤维的结构研究及热处理温度的影响

THE STUDIES OF STRUCTURE AND THE EFFECT OF HEAT-TREATMENT TEMPERATURE ON STRUCTURE ON PAN-BASED CARBONFIBRES

本文利用Ｘ射线衍射方法，讨论了ＰＡＮ基碳纤维的微观结构及微观结构随热处理温度的变化关系．指出ＰＡＮ基碳纤维由乱层石墨和单层碳原子面双相构成，同时进一步给出了结构参数Ｌａ、ＬｅＬ（００２），及微晶择优取向度Ｗ随热处理温度的变化规律．

It is discussed that the microstructure and the effect of heat-treatment temperature on microstructure on PAN-based carbon fibre using X-ray diffraction method in the present work. It is concludes that PAN-based carbon fibres consist of turbostratic carbon and single graphite-like plane .and it is given that La.Le .L002and Wchange relations with heat-treatment temperature.
