Abstract

Abstract:

Mesophase pitch based fibres(MPF) are prepared by melt spinning method from AR-mesophase pitch. After oxidation and carbonization,mesophase pitch based carbon fibres(MPCF) are obtained. The effects of spinning speed on the diameter,microstructure,surface micro-morphology and mechanical properties of carbon fibres are investigated by means of optical microscope,scanning electron microscope(SEM) and fibre strength tester,respectively. The results show that the average diameter of MPF decreases and its spinnability decline gradually with the increase of spinning speed. When the spinning speed is higher than 330m/min,the lengthwise texture flaws appear on the surface of MPCF and the internal microstructure becomes more disordered. Moreover,the tensile strength of MPCF with 11μm in diameter reaches the maximum of 1786MPa at spinning speed of 330m/min.

Key words: mesophase pitch, carbon fibre, spinning speed, mechanical properties

摘要：

以AR中间相沥青为原料，采用熔融纺丝法制备出中间相沥青纤维，再经预氧化和炭化处理得到中间相炭纤维。采用光学显微镜、扫描电镜（SEM）及纤维拉力仪等手段，研究了熔融纺丝速度对中间相炭纤维直径、内部微观结构、纤维表面微观形貌及纤维力学性能的影响。研究结果表明，随着纺丝速度的增大，中间相沥青纤维平均直径减小，可纺性逐渐下降；当纺丝速度大于330m/min时，中间相炭纤维表面出现纵向纹理缺陷，纤维内部微观结构变得无序；在纺丝速度为330m/min时，炭纤维拉伸强度达到最大值1786MPa，此时纤维直径为11μm。
