MESH-LIKE FIBER-REINFORCED COMPOSITE MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a mesh-like fiber-reinforced composite material which is excellent in elasticity, drape properties, moldability into a shape having a curved surface and gas permeability, prevents stuffiness and is light and high-strength.SOLUTION: A mesh-like fiber-reinforced composite material has a mesh-like knitted structure 1 composed of a plurality of longitudinal knitted structures 20 formed such a way that chain knitting yarn 2 forms loop-like chain knitting stitches 2A continuous in the longitudinal direction and insertion yarn 3 which is inserted into the longitudinal knitted structures 20 in the lateral direction and binds the mutually adjacent knitted structures 20. The mesh-like fiber-reinforced composite material has a curved surface and is formed by impregnating the knitted structures 20 and the insertion yarn 3 in the mesh-like knitted structure 1 exclusively with a resin and then hardening it. At least a part of the chain knitting yarn 2 and the insertion yarn 3 is a carbon fiber strand composed of carbon fiber, and the opening ratio of the mesh-like knitted structure 1 is 20-60%.SELECTED DRAWING: Figure 1
