  • Patent number: 11674243
    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 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.
