Document Type and Number:
Japanese Patent JP6946143
Kind Code:
B2
Abstract:
A composite material repair patch 10 for repairing a part to be repaired of a composite material is provided with: a bonding surface 10, 10c that is bonded to a counterbored hole 6 formed in the part to be repaired, the bonding surface 10, 10c being a surface opposing a surface 15 to be bonded to of the counterbored hole 6; and a surface 10a that is a surface on a side opposite to the bonding surface in a thickness direction. The surface 10a has a curved surface with a first surface-side curvature radius R1 that protrudes toward the surface 10a from the bonding surface 10, 10c in a cross section taken along a plane intersecting an axial direction in the surface. The surface 15 to be bonded to has a curved surface with a second surface-side curvature radius R2 that protrudes toward the opposed bonding surface 10, 10c in a cross section taken along a plane intersecting an axial direction in the surface to be bonded to. The first surface-side curvature radius R1 is smaller than the second surface-side curvature radius R2.
