KOLHALTIG BECKFIBER I STAND ATT HERDAS OCH OMVANDLAS TERMISKT TILL EN FIBER MED EN STRUKTUR SOM EGER DEN TREDIMENSIONELLA ORDNING SOM ER KARAKTERISTISK FOR POLYKRISTALLIN GRAFIT SAMT SETT ATT FRAMSTELLA FIBERN

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.
