    Abstract: A technique for providing localized stiffening of a vehicle trim panel, especially for high curvature areas. The vehicle trim panel includes an outer panel having an outer show surface and an inner surface. A plurality of discrete reinforcement elements are bonded to the inner surface of the outer panel at locations where localized stiffening is desired. The discrete elements can come in a variety of different shapes and sizes, where the combination of elements and the number of elements is selected for a particular trim panel stiffness.

    Abstract: A method for securing sandwich structures together, especially vehicle structures. In one embodiment, two sandwich structures are perpendicularly secured together, where a first one of the sandwich structures includes a micro-truss core having one unit cell geometry and second one of the sandwich structures includes a micro-truss core having different unit cell geometry. The micro-truss core of the second sandwich structure includes a micro-truss extension fabricated at the same time as the micro-truss core and having the same unit cell geometry as the micro-truss core for the first sandwich structure. The extension is inserted in an open area between face sheets in the first sandwich structure so that it abuts against the micro-truss core in the first sandwich structure.

    Abstract: 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.

    Abstract: A fastening assembly includes a panel, a fastener and a primary anode insert. The panel defines an aperture and the fastener includes a shaft portion disposed within the aperture. The primary anode insert may be disposed adjacent to a reaction region of the fastener. Alternatively, the fastening assembly may include a fastener and a primary anode insert. The fastener includes a shaft portion which is configured to be disposed within at least two aligned component apertures. The primary anode insert may be also be disposed adjacent to a reaction region of the fastener.
