| 英文摘要 | The microstructures of t300 and t700 carbon fibers were investigated by scanning electron microscopy, elemental analysis, x-ray diffraction and raman spectroscopy. results showed that the surface of t700 was smooth, whereas ridge-like prominences and grooves were much more obvious on the surface of the t300 fibers, indicating that the former were produced by dry-jet wet spinning and the latter by wet spinning. grain-like features were seen in the cross section areas of both fibers. t700 fibers had a higher carbon content and less nitrogen than did t300 fibers. the difference in microstructure parameters, such as d(002) l-a and l-c, showed that the heat treatment temperature of t700 during manufacture was higher than that of t300. compared with t300, the preferred orientation parameter z of t700 fibers was 2.3 degrees lower, the density 2.27% higher and the microvoid volume 7.54% less. thus it is the densification that produces the higher tensile strength for t700 fibers. |
