Abstract
Official abstract text for this publication.
A composite material member having an FRP layer made of fiber-reinforced plastic, and a resin-rich layer that has a fiber content that is 5% or less of the fiber content of the FRP layer. The resin-rich layer is formed in at least a partial region of a surface of the FRP layer, and is formed from the same resin as a matrix resin of the fiber-reinforced plastic. A hole is bored so as to penetrate the FRP layer and the resin-rich layer.
First claim
Opening claim text (preview).
The invention claimed is: 1. A composite material member comprising: an FRP layer made of fiber-reinforced plastic; a resin-rich layer that has a fiber content that is greater than zero and less than or equal to 5% of the fiber content of the FRP layer, that is formed in at least a partial region of a surface of the FRP layer, and that is formed from the same resin as a matrix resin of the fiber-reinforced plastic; and a hole that is bored so as to penetrate the FRP layer and the resin-rich layer. 2. The composite material member according to claim 1 , wherein the resin-rich layer is formed on surfaces on both sides of the FRP layer, and the hole penetrates the FRP layer and the resin-rich layers formed on the surfaces on both sides of the FRP layer. 3. The composite material member according to claim 1 , wherein the reinforcing fibers of the FRP layer is made of continuous fibers. 4. The composite material member according to claim 1 , wherein a thickness of the resin-rich layer is at least 0.5 mm.
