Title:
MOLDED ARTICLE OF CARBON-FIBER-REINFORCED COMPOSITE MATERIAL AND PRODUCTION METHOD FOR MOLDED ARTICLE OF CARBON-FIBER-REINFORCED COMPOSITE MATERIAL
Document Type and Number:
WIPO Patent Application WO/2020/196600
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a molded article of a carbon-fiber-reinforced composite material that makes it possible to achieve favorable adhesion, regardless of the adhesive or metal used in combination therewith, and that also makes it possible to maintain adhesive force, even after a long period of time has passed after adhesion. A molded article of a carbon-fiber-reinforced composite material that comprises at least carbon fibers and a resin composition. The molded article of a carbon-fiber-reinforced composite material is characterized in that the surface roughness Ra thereof is 0.01-2 μm and in that the tensile shear adhesive strength (F0) thereof when a metal has been adhered to the surface thereof via an adhesive layer that contains an epoxy compound and is 0.1-3 mm thick is 10-40 MPa.
