Structural composite panels for motor homes, recreational vehicles, and trailers

The present disclosure relates to laminate composite panels comprising a first layer of fiberglass reinforced polyester (“FRP”) and a second layer of a polyurethane material. The polyurethane layer can comprise a reaction product between an aromatic polyester polyether polyol and a diisocyanate. The polyurethane is cured-in-place on a surface of the FRP, thus creating a laminate composite material wherein the layers are adhered together without application of a separate adhesive layer. The panels exhibit improved water resistance and strength properties. The laminate composite can be adhered to a second material such as wood, polystyrene, polyurethane, or non-wovens. Such panels are particularly suitable for use in recreational vehicles, motor homes, trailers, and as building materials. Methods of making such laminate composite materials are also provided.
