| 摘要 |
High modulus, high strength carbon fibers, having a highly oriented structure characterized by the presence of carbon crystallites preferentially aligned parallel to the fiber axis, are produced from carbonaceous pitches which have been transformed, in part, to a liquid crystal or so-called "mesophase" state. When heated to graphitizing temperatures, these fibers develop the three-dimensional order characteristic of polycrystalline graphite. |
