A reinforced structural foam article includes one or more skin layers bounding a structural foam layer to form a composite structure. One or more reinforcing layers or members are embedded within the composite structure. The reinforcing layer may include flexible, sheet-like materials, such as woven fabrics, or rigid support members, which may be provided separately or in assemblies or subassemblies. The article may be formed by rotational molding, wherein the reinforcing member or layer is supported within a mold cavity, the skin layers are formed by a first moldable plastic charge, and the intermediate foam layer is formed by a subsequent charge including an appropriate blowing agent. The reinforcing member is then embedded within the article during the molding process. Fittings may be provided for further reinforcement and for attachment of the article into further assemblies or subassemblies. |
