Abstract: A double ended dual attached fastener includes a first portion having a stud bolt, a second portion configured to anchor to a panel member, and a flange nut partitioning the first end and the second end. The flange nut includes a flat interior annular surface facing the second portion. The flange nut includes a plurality of radially spaced weld projections extending toward the second portion. The weld projection includes a material that amendable to form a weld joining the flange nut to a panel member through which the second portion is inserted. The second portion defines a fastener selected from a group consisting of a self-tapping friction screw, a self-piercing rivet, and a swage bolt.

Abstract: A method of joining first and second layers of polymeric composite material includes disposing a portion of a molded insert having a bottom end into a top surface of a first layer of material and then applying a layer of adhesive between the top surface of the first layer and a bottom surface of a second layer of material to create a bond-line thickness. Next, a top surface of the second layer is pierced with a headless end of a fastener and interlocked into the molded insert. A layer of protective coating is then applied to the top surface of the second layer of material to cover the interlocked fastener.

Abstract: Methods for ultrasonic welding of thermoplastic polymer workpieces and assemblies made therefrom are provided. The method may comprise disposing a first region of a first thermoplastic polymer workpiece and a second region of a second thermoplastic polymer workpiece between an ultrasonic horn and an anvil of an ultrasonic welding device. The first workpiece has a preformed deformation and at least one of the first and/or second workpieces has an adhesive precursor applied thereto. The ultrasonic horn or anvil seats within the preformed deformation. Ultrasonic energy is applied from the ultrasonic horn to create a weld nugget between the first and second workpieces. The assembly thus formed has a green strength sufficient to be further processed immediately. The methods provide a robust weld joint with controlled adhesive bondline thickness.
