Abstract

Official abstract text for this publication.

A component made of at least one thermoformable material, having a first layer made of a first material, a second layer made of a second material, and a third layer made of the first material. The three layers form a sheet, which is formed to various shapes, depending upon the part that is to be created. The sheet may be formed to produce the bumper of an automobile, a door panel for an automobile, a flotation device, such as a pontoon for a pontoon boat, or the like. The first and third layers are SMC, and the second layer, or “core,” is disposed between the first and third layers, allowing the strength of the first and third layers to be used more efficiently, compared to a sheet having only the first and third layers, and no core.

First claim
