PANEL ASSEMBLY HAVING MULTI-LAYER PATCH FOR SOUND DAMPING

摘要

A panel assembly with a multi-layer patch may be used in any number of different applications in order to reduce noise or vibrations, provide thermal insulation, and/or improve the structural integrity of an underlying part. In an exemplary embodiment where the panel assembly is a vehicle part, the panel assembly includes a main panel, a primary adhesive layer, and a multi-layer patch that includes at least two individual patches and at least one auxiliary adhesive layer. The primary adhesive layer attaches the multi-layer patch to the main panel, and the auxiliary adhesive layer attaches the individual patches together. The size, shape, thickness and/or composition of the different layers of the multi-layer patch may be specifically chosen to exhibit certain sound and/or thermal damping properties.
