石油沥青基炭纤维的制备
Carbon fibers from petroleum pitch
摘要
Abstract
The stabilization, carbonization and graphitization processes in the preparation of isotropic and anisotropic pitch fibers were studied by elemental analysis, TG, DSC, FT-IR, XRD and STM. The reaction mechanisms were deduced and kinetics parameters evaluated. The change of mechanical properties and crystalline parameters during graphitization were also obtained. Results show that the optimum oxygen content for isotropic pitch The d002, Lc, La of isotropic pitch based graphite fibers (IPGF) are 0.3432,3.432 and 8.053nm respectively, while for anisotropic pitch based graphite fibers (APGF) they are 0.3391, 25.69 and 3.05nm.Tensile strength and modulus are respectively 596MPa and 58GPa for IPGF,and 2956MPa and 632GPa for APGF.关键词
