Abstract
A composite panel for use in applications such as mobile homes, boats, buses, RVs, or other panels used typically in transportation applications, where a single piece, water resistant, lightweight panel with patterned high-strength areas is needed. The composite panel generally includes internal preforms made of low-density material such as urethane foam, which create patterned structural portions of the panel during the molding process. The patterned structural portions are formed by a maze-like region within a mold, into which composite matrix material is infused. The patterned structural portions have high strength compared to the other regions of the panel, and can be used for structural support or for retaining fasteners for appliances, walls, etc.
