A light-weight, highly rigid, high-strength environment-friendly fiber-reinforced plastic (hereinafter, CFRP) board having a surface quality that can endure long-term use suitable for use in automobiles and the like is provided. A method for making the same is also provided. The CFRP board includes a board member formed from a woven fabric as a reinforcing base material, the woven fabric including carbon fibers; and at least one of a gel coat and a paint provided on the board member, wherein the NSIC value of the surface of the CFRP board is 30% or more.

CFRP plate material and method for preparation thereof

The present invention is aimed at providing FRP formed by integrating a fiber reinforcing material and a non-woven fabric, and having excellent shaping ability, impact resistance after molding, and excellent reliability and low cost. The aim of the present invention is achieved by a complex fiber reinforcing material including a sheet-shaped fiber reinforcing material composed of reinforcing fibers, and a non-woven fabric laminated on at least one side of the fiber reinforcing material, wherein the fibers constituting the non-woven fabric pass through the fiber reinforcing material to integrate the non-woven fabric with the fiber reinforcing material.
