An adhesive hook includes a base which has a bottom for fixing, an outer surface, and a hook provided at the outer surface. The bottom of the base is fixed on an external surface by means of an adhesive, and the adhesive is a curable adhesive. The structure of the adhesive hook is simple, and the curing speed of the curable adhesive is fast. After the curing process, the load bearing of the hook is larger than 1 Kg/cm2. Further, the adhesive hook has high cohesion strength after the adhesive is cured, and no remain is pasted on the external surface or the base after the hook is removed. The base can be recoated with new adhesive to reuse, which reduces cost and achieves recycling.

A ultrasonic welding method of joining dissimilar-material workpieces, such as sheet materials, and the joined components formed thereby. The method includes applying ultrasonic energy to a thermoplastic piece to fill a hole of a dissimilar piece to form a weld point that is made up with polymer from the thermoplastic piece. In general, the geometry of the thermoplastic piece is not altered during the process. The dissimilar piece generally has a higher melting temperate and can be metal, thermoset polymers, or other thermoplastic material. The welded pieces can be arranged in a lap, laminate, or double lap configuration. In some embodiments, the hole of the dissimilar sheet material includes undercut features that improve the mechanical interlock between the dissimilar pieces. In some embodiments, the weld point has a mushroom cap to improve mechanical interlock.

A method and apparatus to manufacture a coherent bundle of scintillating fibers is disclosed. A method includes providing a collimated bundle having a glass preform with capillaries therethrough known in the industry as a glass capillary array, and infusing the glass capillary array with a scintillating polymer or a polymer matrix containing scintillating nanoparticles.

A high altitude balloon, including a method and machine for manufacture, uses a perimeter border strip to couple two circular balloon panels with a lap or butt seal. Simultaneous sealing of two perimeter seals, one between the border strip and each of two balloon panels, is provided by supporting stacked balloon panels on a rotatable support and sealing around the full perimeter of the two interposed balloon panels and the border strip. The method and machine for manufacture allow for the mass production of high altitude balloons and minimize necessary material handling. The perimeter border strip can be dispensed and guided relative to the perimeter of the balloon panels for positioning before sealing together, as a bonding device is rotated relative to the balloon envelope.

A first member formed of a thermoplastic resin molding mixed with a fiber material and a second member formed of a molding containing at least a thermoplastic resin are welded by friction stir spot welding using a double-acting tool for friction stir spot welding. An overlapping part between the first member and the second member is formed, and the tool is disposed against the overlapping part while the pin and the shoulder are rotated about the rotation axis. The pin is plunged into the overlapping part, and friction stir is performed to cause extension fibers to remain around a plunging region of the pin while the shoulder is retracted to release an overflow material. The shoulder is brought closer to the overlapping part to wrap the extension fibers into the overflow material when the overflow material is backfilled while the pin is retracted from the overlapping part.
