Title:
COMPOSITE MATERIAL, PREPREG, CARBON-FIBER-REINFORCED MOLDED BODY, AND METHOD FOR MANUFACTURING COMPOSITE MATERIAL
Document Type and Number:
WIPO Patent Application WO/2019/065535
Kind Code:
A1
Abstract:
Provided are a composite material in which the effect of carbon nanotubes can be adequately achieved, a prepreg in which the composite material is used, a carbon-fiber-reinforced molded body having greater resistance to the advance of interlayer peeling and cracking, and a method for manufacturing the composite material. The present invention is characterized by comprising carbon fiber bundles in which a plurality of continuous carbon fibers 12a are arranged, carbon nanotubes 14a affixed to the surfaces of each of the carbon fibers 12a, and a plurality of securing resin parts 16a that partially secure the carbon nanotubes to the surfaces of the carbon fibers 12a, the plurality of securing resin parts 16a covering 7-30% of the surface of the carbon fibers 12a to which the carbon nanotubes 14a are affixed.
