Abstract: A method of riveting a first substrate and a second substrate with a rivet includes delivering a first ultrasonic pulse to a respective exterior surface of the first substrate at a predefined target area, via an ultrasonic device. The first ultrasonic pulse is configured to soften the first substrate at a first softening temperature. The method includes attaching a crust layer on a rivet head of the rivet. A second ultrasonic pulse is delivered to the predefined target area to soften the crust layer at a second softening temperature, via the ultrasonic device. A surface profile of the crust layer is fashioned via compression of a horn inner cavity of the ultrasonic device over the crust layer. The crust layer is cooled to harden into a seal configured to prevent entry of moisture between the rivet and the respective exterior surface of the first substrate, thereby reducing galvanic corrosion.

Abstract: An assembly and method for minimizing an overlap of a composite member riveted to another member includes a first member having a first overlap area and a second member having a second overlap area. The overlap areas of the first and second members are in direct contact, thereby forming an overlapped region. The overlapped region may be thicker than the sum of the individual members. The second member includes an end defining a projection in the overlapped region. The rivet is disposed through the first member and at least partially through the second member in the projection, thereby interlocking the second member to the first member. The projections include a curved symmetrical body defining an apex. The rivet extends through the body such that a line extending from the center axis of the rivet is perpendicular to a tangent extending through the apex of the projection.

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: A two-part mechanical fastener comprising an elongated body with a bore slidably carrying a mandrel adapted to interferingly engage the body is described. The fastener body has one or more protuberances on its exterior surface. In an aspect, the protuberances form a thread. The fastener is adapted to form an opening in, and penetrate, a stack of two or more workpieces. To secure the workpieces in the workpiece stack and form a robust joint, the fastener body is deformed by the mandrel, expanding the body, so that a body end engages a surface of the workpiece stack and the one or more protuberances are brought into engagement with the walls of the opening. Methods of using such a fastener to secure non-ferrous or polymer-based sheet-like workpieces to one another are disclosed.

Abstract: A rivet nut (“rivnut”) installation method and a rivnut structural configuration are disclosed that can be implemented separately in conjunction with one another to serve as an anchor in and/or a workpiece at an installation location. The rivnut installation method involves inserting a rivnut onto an externally threaded mandrel, rotating the mandrel while a free end of the mandrel is in contact with the workpiece, and driving the free end of the mandrel and the rivnut through the workpiece while continuing to rotate the mandrel. The method is particularly useful when the workpiece includes one or more substrate layers composed of a low ductility material such as a polymer composite. The rivnut structural configuration includes the incorporation of an external threading onto at least a portion of a hollow shaft of the rivnut.

Abstract: A method of joining top and bottom layers of material according to the principles of the present disclosure includes providing a rivet having a head and a headless end, wherein a rimmed edge extends downward from the head toward the headless end, applying a layer of adhesive between the top and bottom layers and allowing the adhesive layer to at least partially cure. The method further includes piercing the top layer with a headless end of a rivet after the adhesive layer is cured, deforming the top layer with the rimmed edge and bottom layer with the headless end of the rivet, and forcing the rimmed edge and the headless end of the rivet to bend radially outward during deformation of the top and bottom layers.
