Kohlenstofffaser, Acrylfaser und Verfahren zu deren Herstellung

摘要

The object of the present invention is to provide carbon fibers with high tensile strength as a resin impregnated strand even if the single filaments constituting the carbon fibers are thick. The carbon fibers of the present invention consisting of a plurality of single filaments are characterized by satisfying the following relation: $where\; sigma\; is\; the\; tensile\; strength\; of\; said\; carbon\; fibers\; as\; a\; resin\; impregnated\; strand\; (in\; GPa)\; and\; d\; is\; the\; average\; diameter\; of\; said\; single\; filaments\; (in\; mu\; m).\; The\; carbon\; fibers\; can\; be\; preferably\; used\; as\; a\; material\; for\; forming\; energy-related\; apparatuses\; such\; as\; CNG\; tanks,\; fly\; wheels,\; wind\; mills\; and\; turbine\; blades,\; a\; material\; for\; reinforcing\; structural\; members\; of\; roads,\; bridge\; piers,\; etc.,\; and\; also\; a\; material\; for\; forming\; or\; reinforcing\; architectural\; members\; such\; as\; timber\; and\; curtain\; walls.$
