用煤焦油研制通用级沥青炭纤维

PREPARATION OF GENERAL PITCH CARBON FIBER FROM COAL TAR

以武钢煤焦油为原料，通过原料净化、可纺沥青的调制、沥青纺丝、沥青纤维不熔化和不熔化纤维发化工艺研制通用级炭纤维。所得通用级沥青炭纤维样品平均直径为11．6μm，平均抗拉强度为9O5MPa，平均模量为42．2GPa，平均断裂伸长为2．14％．

With coal tar of WISGCO, general pitch carbon fiber is made in the process ofpurlfying, adjusting, splnnlng, unfusing and carbonizing' The mean diameter of fiber sample is11. 6 μm, mc;ln tensile strength 905 MPa, mean module 42.2 GPa and mean fracture elongationrate 2. 14 %.
