Title: WOVEN ARTICLE FOR CARBON FIBER REINFORCED PLASTIC AND MOLDED PRODUCT FORMED THEREFROM
Abstract:
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.
