Systems and methods for attaching to a surface and applying a calibrated load are described. An example system for attaching to a surface and applying a calibrated load includes a suction cup to attach to an attachment surface and a rocker arm to apply a load to a working surface. The rocker arm is coupled to the suction cup and comprises a portion extending over the suction cup to apply pressure over the suction cup. The system also includes a force scale coupled to the rocker arm to provide an indication of an amount of the load applied to the working surface by the rocker arm.

A repair device is a device configured to repair a plate-shaped composite material formed by laminating fiber-reinforced resin sheets. The repair device includes a main body portion that covers a portion to be repaired that is formed in an end surface configured to connect plate surfaces of the composite material so as to be recessed from the end surface such that a closed space is formed between the end surface and the main body portion, a securing portion configured to secure the main body portion to the composite material, and a resin supply portion configured to inject a resin into the closed space with a pressure. The main body portion is formed of a member with rigidity that is not deformed due to the pressure from the resin supply portion.

Disclosed herein is a method of repairing surface damage in an exterior surface of a hollow bladder, made of a cured elastomer. The method comprises placing first strips, made of an uncured elastomer, at least partially within the surface damage in the exterior surface of the hollow bladder in a side-by-side arrangement. The method also comprises sealing the surface damage, the first strips, and a portion of the exterior surface surrounding the surface damage in a vacuum bag. The method further comprises reducing pressure within the vacuum bag relative to outside the vacuum bag. The method additionally comprises while the pressure within the vacuum bag is reduced, heating the first strips from within the vacuum bag to cure the first strips.

A method for repairing a component constructed in multiple layers from a layer composite material comprises a step of removing material of the layer composite material of the component in the region of damage to the component in order to form a scarfed cutout, such that a scarfed peripheral contour formed from a plurality of layers of the component is formed. Furthermore, fiber-reinforced plastic strips, which exhibit a curable plastic material in an uncured state, are applied in layers in the cutout in order to create a replacement-structure semifinished product that is complementary to and butts against the scarfed peripheral contour of the component. In a further step, the curable plastic material contained in the fiber-reinforced plastic strips is cured in order to create a replacement structure and for joining the replacement structure to the component.

A method of repairing a damaged spar cap of a wind turbine blade of a wind turbine, the damaged spar cap including carbon fiber-reinforced plastic and the method having the steps of: removing a damaged carbon fiber-reinforced plastic part from the damaged spar cap to obtain a corresponding recess in the damaged spar cap, applying an adhesive to the recess, and fitting at least one patch including carbon fiber-reinforced plastic into the recess, is provided.

A tire repair tool includes a body portion and a cartridge portion. The tool is used to inject an adhesive or glue and a patch into a puncture in a tire, while the tire is still engaged with the wheel, in order to permanently patch a punctured inner tube of the tire. More particularly, a push rod is used to rupture an adhesive pod, elevate an elevator assembly and eject the adhesive and patch through an outlet tube of the tool and into the existing puncture of the outer tire. A patch is affixed over a puncture in the inner tube by the adhesive to permanently patch the inner tube without having to remove the tire from the wheel or rim.
