Title:
COMPOSITE MEMBER
Document Type and Number:
Japanese Patent JP2023065897
Kind Code:
A
Abstract:
To provide a composite member in which a reinforcement member is joined to a reinforcement-target member through an adhesive layer, and in which an outermost surface layer in contact with the adhesive layer, of the reinforcement-target member or the reinforcement member is composed of a unidirectional prepreg including reinforcement fiber and thermosetting resin, and in which resistance against peeling, of a joint portion is radically improved, and which therefore has improved load resistance performance.SOLUTION: A composite member is provided in which a reinforcement member having an aspect ratio represented by expression: aspect ratio=projection length of reinforcement member (m)/projection width of reinforcement member (m) of 1 or more and 1,000,000,000 or less is joined to a reinforcement-target member through an adhesive layer, wherein a part or all of an outermost surface layer of the reinforcement member in contact with the adhesive layer is composed of a unidirectional prepreg including reinforcement fiber and thermosetting resin, and an angle α in top view in an orientation direction of the reinforcement fiber of the unidirectional prepreg and a longitudinal direction of the projection length of the reinforcement member is 0°<α<30°.SELECTED DRAWING: Figure 1
