| 英文摘要 | The influence of stretching ratio between 0-2.5 % on inicrostructure and mechanical properties of pan-based graphite fibers was investigated by xrd and mechanical testing for graphitization temperatures of 2 400, 2 700 and 3 000 degrees c. results show that stretching ratios of 1.25, 1.5 and 2.20 % yield a maximum tensile strength of 3.1, 2.55 and 2.25 gpa at 2 400, 2 700 and 3000 degrees c respectively, and the maximum tensile strength is an increase of about 10-20 % compared to the un-stretched samples at the same temperature. the elasticity modulus of the graphite fibers increases with stretching ratio at the different temperatures investigated and is 15% larger than that of the un-stretched samples at a stretching ratio of 2.5 %. the size of crystallites lc (3.612-7.094 nm), la (12.909-24.400 nm) and orientation degree of crystallites (89.51-92.97 %) increase, but do, (0.3465-0.3418 mn) decreases with the stretching. this contributes to the increase of tensile strength and modulus of the graphite fibers. |
