A structural composite material is provided. The material comprises a thermoplastic layer, a layer of fibrous material spaced from the thermoplastic layer and a foam core disposed in the space between the layers. A resin impregnates and holds the layer of fibrous material together to form a fiber-reinforced resin structure. The foam core and the fiber-reinforced resin structure are integrally formed from a core material capable of having both a foamed character and a resinous character. A process for manufacturing the composite and a boat structure formed from the material are also provided.

A structural composite material comprising: a thermoplastic layer having an outer surface and an inner surface; a layer of fibrous material disposed in a first region spaced from the inner side of the thermoplastic layer, and a core material capable of having a foamed character and a resinous character joining said thermoplastic layer and said layer of fibrous material, said core material having a foamed character defined by a multiplicity of foam cells in a second region between said inner surface of the thermoplastic layer and said first region of fibrous material and having a resinous character impregnating and holding together the layer of fibrous material to form a fiber-reinforced resin structure in said first region, said composite material having controlled uniformity of thickness, density and resin content throughout.
