CARBON FIBER-REINFORCED COMPOSITE MATERIAL MOLDING AND METHOD FOR PRODUCING THE SAME, AND METHOD FOR REPAIRING CARBON FIBER-REINFORCED COMPOSITE MATERIAL MOLDING

摘要

PROBLEM TO BE SOLVED: To provide a method for improving an interface adhesive strength between a carbon fiber and a resin in a CFRP molding in which a resin is used as a matrix; and a method for repairing lowering of a mechanical strength caused by deterioration, damage and the like due to use of the CFRP molding.SOLUTION: There is provided a CFRP molding in which a resin is used as a matrix. An area ratio of a gap portion between a carbon fiber and the peripheral resin to a cross-sectional area of the carbon fiber in a cross section in a thickness direction of the molding is in a range of 100:10 to 100:0.SELECTED DRAWING: Figure 2
