Abstract

　本発明により、炭素繊維の繊維軸方向に平行な複数の皺をその表面に有し、走査型プローブ顕微鏡を用いて測定する炭素繊維の表面の前記皺の間隔が１２０～１６０ｎｍで、表面の皺の深さが１２～２３ｎｍ未満で、平均繊維直径が４．５～６．５μｍで、比表面積が０．９～２．３ｍ2／ｇで、密度が１．７６ｇ／ｃｍ3以上の炭素繊維が２００００～３００００本収束されてなる炭素繊維ストランドであって、前記炭素ストランドのストランド引張り強度が５９００ＭＰａ以上、ストランド引張り弾性率が３００ＧＰａ以上、張力９．８Ｎで巻取ったボビン上のストランドのストランド幅が５．５ｍｍ以上、走行中の炭素繊維ストランドに張力９．８Ｎを付加して３本のステンレス棒を通過させるストランド割れ評価方法においてストランド割れが観察されない炭素繊維ストランドが開示される。
