高导热中间相沥青基炭纤维的微观结构研究
Microstructure of high thermal conductivity mesophase pitch-based carbon fibers
摘要
Abstract
Themicrostructural characteristics of high thermal conductivity mesophase pitch-based carbon fibers were investig-ated by XRD, Raman spectroscopy, SEM and TEM. The relationship between microstructural characteristics and thermal conductiv-ity is discussed. Results show that the radial structure is always accompanied by a splitting stucture. La has more significant impact on the thermal conductivity than Lc. The Raman spectroscopy ID/IG value of the cross section was used as an essential index to evalu-ate the thermal conductivity of the carbon fibers. The microstructural characteristics including large graphite crystallite size, high pre-ferred orientation along the fiber axis, and few defects contribute to the high thermal conductivity of the carbon fibers.关键词
