在聚丙烯腈基碳纤维原丝纺丝过程中,在干燥致密化之前使用不同的油剂上油,干燥致密化不同的时间,制得PAN纤维。利用SEM、XRD、纤维细度仪、纤维强伸度仪等分别对PAN纤维的表面形貌、晶体结构、纤度、强度、断裂伸长率和体密度进行研究。结果表明油剂可以有效防止纤维变形、粘连、并丝和表面缺陷的产生;随着致密化时间的增加,PAN纤维晶面间距、晶粒尺寸和断裂伸长率变小,结晶度、强度和体密度变大,纤度不变;使用不同的油剂和浓度,最后得到的PAN纤维的性能不同。

In the production ot PAN precursor for carbon fiber, PAN fiber was prepared by finishing different oil agent before collapsing and being treated in different time during collapsing. The surface morphologies, crystalline structure, fiber fineness, tensile strength, elongation at break and bulk density of PAN fiber were studied bySEM,XRD,fiber fineness instrument and fiber strength and elongation instrument. The results show that oil agent can effectively prevent deformation,adhesion, cohering and surface defect of the fiber . With the increase of collapse time, lattice spacing, crystalline size and elongation at break are decreased, but crystallinity, tensile strength and bulk density are increased, and fiber fineness is unchanged. By using different oil agent and concen- tration,the properties of PAN fiber are different.
