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.
A bonnet for an automobile, having an outer member made from FRP and an inner member made from FRP and joined to the back-surface side of the outer member, wherein the outer member has a high-rigidity section having a rigidity higher than a rigidity of the central section of the outer member along an outer edge of the outer member, and the inner member is joined to the outer member at the high-rigidity section. While being achieved an advantage of weight lightening of the bonnet by making it from FRP, the rigidity at a required portion is efficiently increased without damaging moldability, a design feature of the bonnet surface can be maintained at a good level, and in addition, performance of the bonnet relating to the protection of a pedestrian at a collision accident etc. can also be sufficiently enhanced.
