Title
(EN) CARBON FIBER BUNDLE WITH ADHERED SIZING AGENT
(FR) FAISCEAU DE FIBRES DE CARBONE AVEC AGENT D'APPRÊT COLLÉ
(JA) サイジング剤付着炭素繊維束
Abstract
(EN) A carbon fiber bundle with an adhered sizing agent, which comprises a carbon fiber bundle and a sizing agent adhered to the surface thereof, provides a carbon fiber bundle with elevated abrasion-resistance, and at the same time superior fibrillation. The carbon fiber bundle with an adhered sizing agent is characterized in that the sizing agent contains an epoxy compound, and in a measurement at 25°C, the intersection of the storage modulus and the loss modulus shows an angular frequency within a range of 1 x 10 5 – 1 x 109 rad/sec.
(FR) Un faisceau de fibres de carbone avec un agent d'apprêt collé, comprenant un faisceau de fibres de carbone et un agent d'apprêt collé sur sa surface, fournit un faisceau de fibres de carbone présentant une résistance élevée à l'abrasion, ainsi qu'une fibrillation supérieure. Le faisceau de fibres de carbone avec un agent d'apprêt collé est caractérisé en ce que l'agent d'apprêt contient un composé époxy, et dans une mesure à 25 °C, l'intersection du module de stockage et du module de perte présente une fréquence angulaire dans une plage de 1 x 10 5 – 1 x 109 rad/sec.
(JA) 炭素繊維束およびその表面に付着したサイジング剤からなるサイジング剤付着炭素繊維束であって、該サイジング剤はエポキシ化合物を含有するとともに、25℃での測定において貯蔵弾性率と損失弾性率との交点を角周波数1×10~1×10rad/secの範囲内に示すことを特徴とする、サイジング剤付着炭素繊維束により、擦過性が高く、同時に開繊性に優れる炭素繊維束を提供する。
