    摘要: Carbon fibers having a high tensile strength satisfy the relationship represented by formula (1) and one of the relationships represented by formulas (2) to (5): La ≥ 1 La ≤ − 0.5 + 0.01 × TM when 170 ≤ TM ≤ 230 La ≤ − 37.3 + 0.17 × TM when 230 TM ≤ 240 La ≤ − 2.5 + 0.025 × TM when 240 TM ≤ 300 and La ≤ 2 + 0.01 × TM when 300 TM where La is a crystal size in nm in a direction parallel to an axis of the fibers measured with by X-ray diffraction, and TM is a tensile modulus in GPa.
