Abstract: A repair patch for damaged sections of panels made of composite materials, wherein the damaged section of the panel has been cut out by, for example, a hole cutting saw, includes a bolt which is inserted through the hole and a rigid washer on the bolt, of about the same diameter as the hole. A flexible washer, substantially larger than the hole, is pushed through the hole and the rigid washer bears against it. The flexible washer has radiating flukes, extending from a central hub region, which can bend when the flexible washer is pushed through the hole, and then spring back to about their original shape on the blind-side. One edge of the flukes is curved which causes the flukes to twist and present only one edge to the edge of the hole as the flexible washer is pushed through, to facilitate passage of the flexible washer through the hole.

The flexible washer has radiating flukes, extending from a central hub region, which can bend when the flexible washer is pushed through the hole, and then spring back to about their original shape on the blind-side. One edge of the flukes is curved which causes the flukes to twist and present only one edge to the edge of the hole as the flexible washer is pushed through, to facilitate passage of the flexible washer through the hole.

Abstract: An elastic patch for the repair of a hole in an interior wall. This patch is easy to apply and requires no tools. The patch has a pressure sensitive adhesive backing which can be affixed to the wall surrounding the hole. Peripheral portions of the patch are thinner than that portion of the patch disposed over the hole itself. This tapering in the thickness of the patch allows it to be blended in with the rest of the wall so that when the patch is covered with paint, the patch becomes unnoticeable and at the same time this tapering gives the patch a thick central region where strength is needed. A material having a high elasticity is used for the patch so that it can absorb shocks to the wall and then spring back to its original shape, thereby preventing any reoccurrence of damage in the area of the wall protected by the patch.
