摘要： PROBLEM TO BE SOLVED: To provide a carbon fiber capable of realizing excellent characteristics in various composite materials corresponding to their applications, to provide a precursor fiber to the carbon fiber, and to provide a method for producing the precursor fiber.
SOLUTION: A bundle of the carbon fiber contains 70 wt% or more of single fibers of which the each consists of the carbon fiber and has a ratio of a single fiber torsional strength to a single fiber torsional modulus of elasticity of ≥0.1. The acrylonitrile-based precursor fiber to the carbon fiber has such a total draw ratio and a size of crystalline region as to satisfy the inequalities: (size of crystalline region, in nm)≥0.92×(total draw ratio)+6; and (total draw ratio)≥6, wherein the size of crystalline region is obtained from reflection of (100)-surfaces of polyacrylonitrile. The method for producing the acrylonitrile-based precursor fiber to the carbon fiber comprises drawing the fiber in a wet-heat state at a draw ratio in a specified range, before densifying the fiber in a dry state.
