【摘要】

：

在聚丙烯腈基碳纤维(PANCF)制备过程中会有40％-50％的重量损失，主要发生在300-800℃范围内。对PAN裂解失重行为的研究有利于理解PANCF类石墨结构的形成机理，并在工业上有助于提高炭化收率。本论文通过热重分析法(TGA)来模拟PAN的裂解失重过程，主要有三个主要裂解阶段。与惰性气氛相比在空气中进行稳定化能提高纤维抗裂解能力，碳化收率高。拉曼分析结果表明高氧含量容易在纤维中形成较多的结

碳纤维微晶取向结构的形成

作为典型的各向异性材料，碳纤维的微晶取向结构是影响其力学性能的关键因素，聚丙烯腈原丝在热稳定化完成后，原有的微晶结构消失，碳纤维的微晶取向则在低温碳化过程中重新初步形成。本论文采用X-射线衍射法研究了碳纤维微晶取向形成的初始阶段，温度以及牵伸对微晶取向结构形成的影响规律，研究结果表明，在1000℃的低温碳化阶段，随着碳化温度的提高，由非碳元素的不断脱除引起的收缩张力导致形成的碳微晶沿轴向排列，取向
