Title (EN) WOVEN ARTICLE FOR CARBON FIBER REINFORCED PLASTIC AND MOLDED PRODUCT FORMED THEREFROM
(FR) ARTICLE TISSÉ POUR PLASTIQUE RENFORCÉ DE FIBRES DE CARBONE ET PRODUIT MOULÉ FORMÉ À PARTIR DE CELUI-CI
(KO) 탄소 섬유 강화 플라스틱용 직조물 및 이로부터 형성된 성형품
Abstract: front page image
(EN) A woven article for a carbon fiber reinforced plastic according to the present invention is a woven article of a spun yarn containing: about 10 wt% to about 60 wt% of a carbon fiber staple in which the content of carbon components is equal to or greater than about 97 wt%; and about 40 wt% to about 90 wt% of a thermoplastic resin fiber, wherein the carbon fiber staple is obtained by carbonizing carbon fiber reinforced plastic scrap at a temperature of about 900 to about 1400°C. The woven article for a carbon fiber reinforced plastic includes a carbon fiber staple manufactured from scrap generated during the manufacture of the carbon fiber reinforced plastic, and allows economic recycling of the carbon fiber reinforced plastic scrap without a reduction in mechanical properties. When molded, productivity is high due to a short cycle time, there is almost no orientation, and an excellent flexural modulus is exhibited.
(FR) Un article tissé pour un plastique renforcé de fibres de carbone selon la présente invention est un article tissé à partir de fil filé contenant : environ 10 % en poids à environ 60 % en poids de fibres de carbone courtes dans lesquelles la teneur en composants de carbone est supérieure ou égale à environ 97 % en poids ; et d'environ 40 % en poids à environ 90 % en poids d'une fibre de résine thermoplastique, où les fibres de carbone courtes sont obtenues par carbonisation de déchets de plastique renforcé de fibres de carbone à une température d'environ 900 à environ 1400 °C. L'article tissé pour un plastique renforcé de fibres de carbone contient des fibres de carbone courtes fabriquées à partir de déchets produits pendant la fabrication du plastique renforcé de fibres de carbone, et permet un recyclage économique des déchets plastiques renforcés de fibres de carbone sans réduction des propriétés mécaniques. Lorsque le produit est moulé, la productivité est élevée en raison d'un temps de cycle court, il n'y a pratiquement pas d'orientation, et il présente un excellent module de flexion.
(KO) 본 발명의 탄소 섬유 강화 플라스틱용 직조물은 탄소 성분의 함량이 약 97 중량% 이상인 탄소 섬유 스테이플 약 10 내지 약 60 중량% 및 열가소성 수지 섬유 약 40 내지 약 90 중량%를 포함하는 방적사의 직조물이며, 상기 탄소 섬유 스테이플은 탄소 섬유 강화 플라스틱 스크랩을 약 900 내지 약 1,400℃에서 탄화시킨 것을 특징으로 한다. 상기 탄소 섬유 강화 플라스틱용 직조물은 탄소 섬유 강화 플라스틱 제품 제조 시 발생하는 스크랩으로부터 제조된 탄소 섬유 스테이플을 포함하는 것으로서, 기계적 물성 등의 저하 없이, 경제적으로 탄소 섬유 강화 플라스틱 스크랩을 재활용할 수 있고, 성형 시, 사이클 타임이 짧아 생산성이 높고, 방향성이 거의 없고 우수한 굴곡탄성률을 갖는다.
