Abstract: A panel assembly is formed by a plurality of bonds between two sheet materials in a face to face relationship to form a preform. The plurality of bonds define a closed perimeter region between the two sheet materials and an open perimeter region between the two sheet materials. The preform may be formed into a predefined shape. Pressurized fluid is applied through an inlet into the open perimeter region to expand the preform. The pressurized fluid expands the open perimeter region such that the two sheet materials expand in an opposing direction, thereby defining an expanded open perimeter region. The closed perimeter region between the two sheet materials remains vacant of the pressurized fluid such that the closed perimeter region is not expanded. The expanded open perimeter region is filled with a filler material for improving a performance characteristic of the panel assembly, e.g., strength, sound absorption, or stiffness.

Abstract: An energy management system for a vehicle includes a load-bearing component operatively positioned in a wheel cavity rearward of a tire and wheel assembly in the wheel cavity. The load-bearing component is configured to limit movement of the tire and wheel assembly in the wheel cavity under a load applied to the vehicle forward of the tire and wheel assembly and offset from a longitudinal centerline of the vehicle.
