A method of repairing a surface defect with a patch is provided. A fibrous substrate is impregnated with a formulation that includes a polyester resin, a crosslinking agent, a solvent, and a particulate filler. The fibrous substrate is contacted with the surface defect. The formulation is exposed to actinic radiation to induce cure of the formulation to form the patch to repair the surface defect. A kit is also provided that includes a bottle containing the formulation. A sheet of fibrous support material is also provided that is adapted to receive the formulation therethrough. Instructions for repairing a surface defect by the aforementioned method are also provided as part of the kit. 3D printing of an article to fit in the surface defect is also disclosed.

A method of repairing a sandwich structure includes: removing a damaged portion of a core and a damaged portion of a first facesheet to form an open volume; filling the open volume with an ultraviolet-curable photomonomer; partially curing the ultraviolet-curable photomonomer to form a plurality of photopolymer waveguides by utilizing ultraviolet light; and arranging a replacement facesheet on the damaged portion of the first facesheet and over the photopolymer waveguides.

A method for repairing damage to a composite part includes creating an aperture through the composite part and preparing the surfaces surrounding the aperture on both sides of the part; inserting a plurality of resin impregnated fibers through the aperture and spreading the end portions of the plurality of fibers radially against the prepared surfaces on both sides of the part; and maintaining contact of the plurality of fibers with the prepared surfaces while the resin cures.

A tire patch clamp assembly for sealing a cut in a pneumatic tire may include an inner plate inserted through the cut and placed on an inside surface of the pneumatic tire. An outer plate is placed on an outside surface of the pneumatic tire. The outer plate is coupled to the inner plate with a threaded rod and a secondary pin. A nut is coupled to the inner plate for receiving the threaded rod. A cam handle assembly is attached to the threaded rod and extends from the outer plate. The cam handle assembly turns the threaded rod in the nut to adjust the distance between the inner plate and the outer plate until the cut is sealed between the inner plate and the outer plate.

Several aspects of this disclosure relate to a reusable kit and it method of use for repairing a leak in a gas-filled inflatable object. In one form, the kit may include: a hollow housing with a leading end region and a trailing end region; a plunger with a front end region and a back end region, the front end region having a tubular nose, the front end region being adapted to be received in the leading end region of the hollow housing; a plug having a head portion and a shaft portion extending therefrom, the shaft portion of the plug being adapted to be mounted at least partially in a tubular nose of the front end region of the plunger; a sealing ring that surrounds the plunger proximate the front end region thereof, the sealing ring serving to interface with an inner wall of the hollow housing; and an adhesive provided below an underside of the head portion of the plug.

A tire plug apparatus for repairing a hole in a tubeless tire on a rim using a tire plug is provided. The tire plug apparatus includes: a body configured to receive an insertion tip for inserting the tire plug into the hole; an adjustable stabilizing arm or strap configured to attach to the body and adjust to contact the tire or rim in order to stabilize the body with respect to the hole; and a motor within or otherwise attached to the body. The motor is configured to: supply an insertion force to insert the received insertion tip into the hole in order to insert the tire plug into the hole using the insertion tip while the body remains stabilized with respect to the hole; and supply an extraction force to extract the inserted insertion tip from the hole while leaving the inserted tire plug in the hole.

The present invention relates to a plug comprising a porous material. These plugs can be used for sealing a puncture in a tyre. These plugs can allow a consumer to quickly and effectively seal a puncture.
