聚丙烯腈基碳纤维的制备及其结构

ＰＡＮ纤维是当今制造碳纤维的最重要原料，由ＰＡＮ原丝制备碳纤维的工艺被广泛地研究．许多测试技术提供了有关ＰＡＮ基碳纤维结构的宏观和微观特征方面的信息．已有一些结构特征被理解和接受．本文介绍了ＰＡＮ基碳纤维的制备及其高模量ＰＡＮ基碳纤维的结构．

THE PREPARATION STRUCTURES OF PAN-BASED CARBON FIRES

Polyacrylonitrile(PAN)is the most important precursor material form Which canbon fibres are produced at present.The preparation material by which PAN-based carbo fibres are Produced is studies widely,many test techniques have provided varioususeful information about the structural characterization of PAN-based carbon fires, somestructural features have understood adn accepted .In thhis paper. the preparationmthod of PAN-based carbon fibres and the structures of high modulus PAN-based carbon fibres rae indicated.
