Multi-layer laminate structure

摘要

The present invention relates to a multi-layer laminate structure. The multi-layer laminate structure includes a foam core element and a fiber-reinforced plastic matrix. The foam core element includes at least an outermost portion that is formed from a closed cell expanded foam, wherein the closed cell expanded foam is expanded polyethylene-polystyrene copolymer foam. The outermost portion of the foam core element is constructed from a material that is not attacked or degraded by the material used in the fiber-reinforced plastic matrix. The fiber-reinforced plastic matrix is formed over the outermost portion of the core element.
