要約
(EN)
Provided is a carbon fiber having higher tensile strength. This carbon fiber satisfies the relational expression of formula (1) and the relational expression of one of formulae (2)-(5). La ≥ 1 (1) In cases where 170 ≤ TM ≤ 230, La ≤ -0.5 + 0.01 × TM (2) In cases where 230 < TM ≤ 240, La ≤ -37.3 + 0.17 × TM (3) In cases where 240 < TM ≤ 300, La ≤ -2.5 + 0.025 × TM (4) In cases where 300 < TM, La ≤ 2 + 0.01 × TM (5) In the formulae, La represents a crystallite size (nm) in a direction parallel to the fiber axis as determined by X-ray diffraction; and TM represents a tensile modulus of elasticity (GPa).

L'invention concerne une fibre de carbone présentant une résistance à la traction plus élevée. Cette fibre de carbone satisfait à l'expression relationnelle de la formule (1) et à l'expression relationnelle de l'une des formules (2) à (5). La ≥ 1 (1) dans les cas où 170 ≤ TM ≤ 230, La ≤ -0,5 + 0,01 × TM (2) dans les cas où 230 < TM ≤ 240, La ≤ -37,3 + 0,17 × TM (3) dans les cas où 240 < TM ≤ 300, La ≤ -2,5 + 0,025 × TM (4) dans les cas où 300 < TM, La ≤ 2 + 0,01 × TM (5). Dans les formules, La représente une taille de cristallite (nm) dans une direction parallèle à l'axe de la fibre tel que déterminé par diffraction des rayons X; et TM représente un module d'élasticité en traction (GPa).
