A bicycle tool according to the disclosure comprises a valve connection means. A tool element is connected with the valve connection means. The tool element is connected with the valve connection means in its longitudinal direction such that an elongated bicycle tool is formed.

A method for repairing a part made of composite material includes producing a recessed section by removing the composite material at a damaged area, producing grooves extending on the two faces of the part from edges of the recessed section, producing orifices in the part opening out into the grooves, tree-dimensional weaving of a filling part fiber preforms including a central section having a shape corresponding to the shape of the recessed section and fiber bundles extending from the central section, placing the filling preforms respectively on either face of the part with the fiber bundles in the grooves on the faces of the part and in the orifices such that the fiber bundles open out into the grooves present on the opposite face of the part, impregnating the filling fiber preforms with a precursor resin of a matrix, transforming the resin into a matrix to obtain a filling part.

A method for repairing a composite structure using pre-cured plugs. In accordance with one method, composite material is removed from a first composite laminate to form a cavity bounded by a tapered internal surface that extends from an opening at an outer mold line surface of the first composite laminate. In addition, a second composite laminate is machined to form a plug having a tapered surface. Then the plug is placed so that the tapered surface of the plug opposes the tapered internal surface of the first composite laminate. Thereafter, the tapered surface of the plug is bonded to the tapered internal surface of the first composite laminate. Optionally, a hole is drilled in the plug for receiving a fastener.

A hole plug that can be used during rework or repair of a composite fiber assembly includes various features that allow placement of a vacuum force to the surface being reworked or repaired. In some implementations, the hole plug can include a plurality of nubs positioned around a shank. The nubs can secure the hole plug to the composite fiber assembly until a cure of an adhesive. The hole plug can further include a plurality of longitudinally oriented grooves extending along the shank and positioned between the plurality of nubs, and can include a notch positioned circumferentially around the shank. The grooves and notch can be used as adhesive carriers that assist with dispersal of a sufficient volume of the adhesive onto other portions of the shank and the composite fiber assembly during insertion of the hole plug into a hole in the composite fiber assembly.

The tire repair tool is used for repairing a damaged tire. The tire repair tool plugs the damaged tire. The tire repair tool is configured for use with an impact wrench. The impact wrench is a pneumatic device that drives the working element of the tire repair tool into the damaged tire such that the tire repair tool can deposit a plug in an aperture formed through the damaged tire. The tire repair tool comprises a needle structure, a stop collar, and a locking nut. The stop collar and the locking nut attach to the needle structure. The needle structure forms the working element of the tire repair tool that inserts the plug into the damaged tire. The stop collar limits the depth of insertion of the tire repair tool into the damaged tire. The locking nut fixes the position of the stop collar relative to the needle structure.
