Abstract: A laminate panel is described. The panel comprises. A core layer disposed between and bonded to each of a first metal layer and a second metal layer. The core layer comprises a fibrous layer, a first adhesive layer interposed between the first metal layer and a fibrous layer, and a second adhesive layer interposed between the second metal layer and the fibrous layer. Ideally, each of the first adhesive layer and the second adhesive layer impregnate and at least partially saturate the fibrous layer. The first adhesive layer and the second adhesive layer each comprise a thermoplastic resin. The panel is useful inter alia in structural applications (e.g., office building walls and the like) and non-structural applications (e.g., vehicular body panels and the like).

Abstract: A cargo vehicle has lightweight rigid panels formed of metal skins and intervening paper layer. Laminate panels are formed using a heated press.

Abstract: A method of laminating and forming a non-planar composite part from a pair of metal skins having an intervening paper layer in a single operation maintains a uniform pressure between die faces. The paper layer may be degassed prior to the lamination/forming process.

Abstract: A fibrous core material having a plurality of weight-reducing holes formed therein is disposed between and bonded to metal skins to form a structural laminate having comparable strength to steel sheets of greater weight.
