摘要
使用高温石墨化炉对实验室自制的高强中模碳纤维进行连续石墨化处理,制备得到了强度4.86 GPa、模量541 GPa的高强高模碳纤维,并详细研究了石墨化处理过程中主要工艺参数对碳纤维结构与性能的影响。研究结果探索掌握了低温石墨化（1 600~2 200℃）过程中,不同处理温度对碳纤维密度、拉伸强度、拉伸模量等性能的影响规律。
Continuous graphitization of high strength and middle modulus carbon fibers made in our laboratory were conducted in high temperature graphitization oven. High strength and high modulus carbon fibers with the strength of 4.86 GPa and modulus of 541 GPa were achieved. Effects of the main technologies parameters in the process of high temperature graphitization on the microstructure and properties of carbon fibers were studied. In this paper, effect of graphitization temperature on the density, tensile strength and tensile modulus of carbon fibers were studied in the process of low-temperature graphitization（ from 1 600 ℃ to 2 200 ℃）.
