According to an embodiment, a rivet includes a first cap having a front side and a back side. The first cap includes a compressed region or a slotted region between a first edge of the first cap and a second edge of the first cap, a unique identifier on the front side of the first cap, a protruding portion extending from a central region on the back side of the first cap, a foam layer adhered to the back side of the first cap with a first layer of adhesive, and a protective film adhered to the foam layer with a second layer of adhesive.

A method for joining at least two structural parts includes a fitting step in which a joining element is driven into the first structural part while a residual material thickness is maintained, and a joining step in which the joining element driven into the first structural part is connected to the second structural part. The joining element has a hollow element shaft, which is driven into the first structural part, and an element head, which is welded or adhesively bonded to the second structural part.

A fastener assembly for use with one or more workpieces. The fastener assembly can be a single-sided (i.e., blind) fastener assembly in which the fastener assembly is inaccessible from one side of the workpiece(s). In this regard, the workpiece(s) can make-up an enclosed component, for example. The fastener assembly can have a fastening end, such as a threaded stud, for securement with a distinct component that is otherwise detached from the fastener assembly. The workpiece(s) can be composed of a carbon fiber composite material, an aluminum material, or another type of material.

A joining element for manufacturing a connection between at least two components, which includes: a head at a first axial end, an end portion at a second axial end opposite the first axial end, and a shaft arranged between the end portion and the head, wherein the shaft defines a longitudinal axis of the joining element between the first and the second axial end. At least the shaft and the end portion of the joining element comprise a hardened edge layer so that a material of the shaft and the end portion has in the interior a lower hardness compared to an adjacent surface of the edge layer.

According to an embodiment, a rivet includes a first cap having a front side and a back side. The first cap includes a compressed region or a slotted region between a first edge of the first cap and a second edge of the first cap, a unique identifier on the front side of the first cap, a protruding portion extending from a central region on the back side of the first cap, a foam layer adhered to the back side of the first cap with a first layer of adhesive, and a protective film adhered to the foam layer with a second layer of adhesive.

A method for applying a polymerizable sealant using a device. The device includes a substantially cylindrical cartridge containing an activated polymerizable sealant. The cartridge has a distribution end and a piston. A receptacle of the cartridge having a connection interface with the distribution end thereof. The pressure acting on the piston of the cartridge ejects the activated sealant through the distribution end. An assembly of the device has a nozzle including an application orifice and a pipe to bring the sealant into the nozzle. A closure needle of the device moves in translation between a closed position where the end of the needle obstructs the application orifice of the nozzle and an open position where the end of the needle is distant from the application orifice.

An electromagnetic effect suppressing termination part for a fastener formed of a metallic material, the fastener having a head, a shank, and a male threaded portion opposite the head, has a metallic core coated by a layer of dielectric material. An internal bore of the termination part includes an inner wall, a counterbore hole, and a cavity disposed therebetween. An outer surface includes an outer wall, and a frustoconical wall positioned proximally relative to the outer wall, the frustoconical wall extending radially outwardly from the outer wall and having an included angle of less than approximately 90 degrees. A seal is disposed in the counterbore hole, and the frustoconical wall is configured so that a compressive force applied to the frustoconical wall deforms the inner wall to conform to the male threaded portion of the fastener and deforms the seal to fill the cavity.

A method for joining at least two structural parts includes a fitting step in which a joining element is driven into the first structural part while a residual material thickness is maintained, and a joining step in which the joining element driven into the first structural part is connected to the second structural part. The joining element has a hollow element shaft, which is driven into the first structural part, and an element head, which is welded or adhesively bonded to the second structural part.

A blind fastener system including a sleeve and, optionally, a core bolt insertable into the sleeve, wherein at least one of the sleeve and the core bolt includes a lubricious metallic coating containing at least one of tin, bismuth, indium and aluminum.

A method of protecting a repair joint having at least two workpieces joined by a fastener includes selecting a preformed functional body based on at least one joint characteristic and applying the preformed functional body to cover the fastener and at least a portion of one of the workpieces. Generally, the preformed functional body inhibits contamination or moisture ingress at a joint interface, and especially in a repair operation. The preformed functional body in one form defines a material that undergoes a color change to indicate a state of cure, and in another form is cured by UV light, moisture, or heat after application.
