A process for gluing on an industrial scale, preferably by using hot-melt adhesives, substrates, preferably made of plastic material, by nano-modifying the adhesives through the addition of particles sensitive to electromagnetic fields and electromagnetic induction coupling. The present invention also relates to a simple, low-cost and environment-friendly (i.e., eco-compatible) separation of various components glued by way of the adhesives through the use of the same equipment and the same type of process. Furthermore, the present invention also relates to repairing glued junctions made by way of the adhesives.

Repair materials made of at least unvulcanized rubber are applied on a repair site of a damaged part of a tire, heating pads are applied on surfaces of the repair materials, wood pieces or other stuffing members differing in size are stuffed inside the tire, in a tire circumferential in tire circumferential direction where the repair materials are applied. The tire circumferential is fastened and pressed from surroundings by bands, and the repair site is heated by the heating pads to vulcanize the unvulcanized rubber of the repair materials, to thereby repair the tire. This repair method provides a low-cost tire repair method capable of maintaining the shape of the tire at the time of pressing and vulcanization, in various kinds of tires.

An assembly to repair a thermoplastic composite. The assembly includes a heating device positioned on opposing sides of the thermoplastic composite. The heating device includes one or more susceptor with a Curie temperature to heat the thermoplastic composite. A pressure device applies a compressive force to the heating device. A pressure distribution device is positioned between the heating device and the thermoplastic composite. The pressure distribution device distributes the compressive force from the pressure device over areas of the opposing sides of thermoplastic composite.
