Marine decking with sandwich-type construction and method of making same
11701856 · 2023-07-18 · ·

A marine deck member and the process for forming the same are provided. The marine deck member comprises a sandwich-type composite panel made by a compression molding process. In such a process, the panel is made by subjecting a heated stack of layers of material to cold pressing in a mold. The cellular core has a 2-D array of cells, with end faces open to the respective layers or skins. The surface traction of this type of composite panel can be enhanced for marine deck applications by controlled debossing, or embossing, of the first skin while it cools in the compression mold. The debossing effect can be affected by applying pressurized gas, e.g., pressurized air, onto the outer surface of the first skin while in the compression mold. The embossing can be affected by applying vacuum pressure on the outer surface of the first skin while in the compression mold.
