Title
(EN) CARBON FIBER PRODUCTION METHOD AND CARBON FIBER PRODUCED USING SAME

Abstract
(EN) The present invention relates to a carbon fiber production method whereby a carbon fiber precursor fiber produced from a polymer having a narrow molecular weight distribution is used, and right before the carbon fiber is wound, a small amount of only a levelling agent comprising a specific ingredient is applied to the surface of the carbon fiber. According to the present invention, a carbon fiber which has excellent dispersibility and of which the grade and quality does not deteriorate may be stably produced, even when a sizing agent is not attached to the surface of the carbon fiber, and the produced carbon fiber is appropriate for use as a high temperature processing composite material using a thermoplastic resin.
(FR) La présente invention concerne un procédé de production de fibre de carbone par lequel une fibre précurseur de fibre de carbone produite à partir d'un polymère ayant une distribution de poids moléculaire étroite est utilisée, et juste avant que la fibre de carbone ne soit enroulée, une petite quantité d'un seul agent d'égalisation comprenant un ingrédient spécifique est appliquée à la surface de la fibre de carbone. Selon la présente invention, une fibre de carbone qui présente une excellente dispersibilité et dont la classe et la qualité ne se détériorent pas peut être produite de manière stable, même lorsqu'un agent d'encollage n'est pas fixé à la surface de la fibre de carbone, et la fibre de carbone produite convient à une utilisation en tant que matériau composite de traitement à haute température utilisant une résine thermoplastique.
(KO) 본 발명은 분자량 분포가 좁은 중합체로 제조된 탄소섬유 전구체 섬유를 이용하고, 탄소섬유를 권취하기 직전에 특정 성분으로 구성된 소량의 평활제만을 탄소섬유 표면에 부여하는 것을 특징으로 하는 탄소섬유의 제조방법에 관한 것으로, 본 발명에 의하면 탄소섬유 표면에 사이징제가 부착되지 않은 상태에서도 분산성이 우수하고 품위와 품질이 저하되지 않은 탄소섬유를 안정적으로 생산할 수 있을 뿐 아니라 제조된 탄소섬유는 열가소성 수지를 이용하는 고온 가공 복합재료 용도에 적합하다.
