A patch kit and method for repairing a tear in a sidewall of an off-road vehicle tire includes an inside patch component, an outside patch component, and a compressing component for assembling, joining and compressing the inner and outer patch components together with the tire sidewall sandwiched therebetween. The compressing component is a threaded rod and a nut or bolt head to dispose on both ends. The inside and outside patch components are rigid or semi-rigid cupped shells with a hole for the threaded rod, so that the rod may pass through the patches and the tear for compression by tightening a nut. To facilitate tire repair without removing the tire from its rim, a recovery cable is temporarily connected to pull together repair components after they are separately pushed through the tear into the tire.

A method of working a non-conforming exhaust sleeve utilizes a first plate disposed over an outer surface of an exhaust sleeve and a second plate disposed over an inner surface. The exhaust sleeve includes an aft sleeve attached to an aft edge of a cellular layer and the first plate extends from the cellular layer onto the aft sleeve. The second plate is disposed along the inner surface of the cellular layer. A first plurality of fasteners secures the first plate to the second plate through the cellular layer and a second plurality of fasteners secures the first plate to the aft sleeve.

A structural reinforcement member is provided to be affixable to a metallic member. The metallic member defines a stress concentration section at which the metallic member is subject to loading in at least one direction such that stress is generated at the stress concentration section in at least one corresponding principal stress direction. The structural reinforcement member includes a polymer matrix composite (PMC) patch element and a bondline. The PMC patch element includes fibers suspended within a polymer matrix. The bondline is disposed to affix the PMC patch element to a surface of the metallic member at the stress concentration section such that the fibers extend along the principal stress direction.

A repair for a structural element made from a composite material includes a bracket defining a first surface and a second surface. The first surface is adapted for facing the structural element. A chamfer is located on a first end of the bracket. An angle is defined between a plane of the chamfer and a plane of the first surface, the first surface of the bracket being adapted to be disposed adjacent to a side of the structural element. The repair also includes a sealant material between the bracket and the structural element, where the sealant material occupies a space established between the chamfer and the structural element.

A method for patching a depression in a composite parent structure. The method comprises: inserting an insert in the depression; placing a composite patch having a multiplicity of curved flexible members on one side of the composite parent structure in a position where a central portion of the composite patch overlies the insert and the flexible members confront opposing portions of the composite parent structure providing adhesive between the composite patch, the insert, and the composite parent structure; pressing the composite patch against the composite parent structure with sufficient pressure to force the flexible members to conform to the shape of the composite parent structure; and while the flexible members are in a stressed state, curing the adhesive in a manner that causes the flexible members to bond to the parent structure.
