國產與英國聚丙烯腈原絲的結構和性能分析

Structure and Properties of Domestic and England PAN-based Fibers

摘要: 測定了國產原絲和進口原絲的力學性能，并用化學分析、凝膠滲透色譜儀、X衍射儀、熱分析儀、掃描電鏡和光學顯微鏡等手段，對原絲的化學成分、分子量、熱性能、結晶度、取向度以及微觀結構進行了研究，在此基礎上，分析和討論了原絲結構和性能之間的相互關系．

Abstract: The mechanical properties of domestic and England PAN-based fibers are measured.The chemical composition, relative molecular mass, thermal property, crystalinity,orientation and microtructure of two kind of fibers are studied by chemical analysis, GPC,TGA, X-ray and SEM, etc. On the basis, the relationship between these fibers structure and the property is analysized.
