Abstract
A rigid structural foil and a method for forming a rigid structural foil is provided. The structural foil includes at least two layers of metal sheets, valley areas and spacers. The metal sheet layers include metal foil having a thickness of 0.006 in. The valley areas are disposed between compressed and uncompressed portions of the structural foil formed during compression of portions of the structural foil. In addition to the valley areas, the structural foil includes spacers. The spacers within the metal sheet layers provide spacing between portions of the metal layers such that the structural foil functions as both a heat shield and an acoustic shield.
Claims38
A structural foil comprising:
- at least two layers of metal sheets, the at least two layers of metal sheets including a metal foil having a thickness of 0.006 in. or less;
- and
- valley areas disposed on the structural foil wherein the valley areas are formed by compressing a portion of the at least two layers of metal sheets such that the valley areas form between the compressed portion of the at least two layers and an uncompressed portion of the at least two layers.
A method for forming a structural panel, the method comprising:
- forming a layer of metal sheets, the layer of metal sheets including a metal foil having a thickness of 0.006 in. or less;
- and
- compressing a portion of the structural panel to form valley areas, where the valley areas are disposed adjacent the compressed portion of the structural panel and uncompressed portions of the structural panel.
A structural acoustical shield, the shield comprising at least two layers of metal sheets having spacers, the at least two layers including a metal foil having a thickness of 0.006 in. or less where a portion of the at least two layers of metal sheets is are interlocked to form valley areas for the structural acoustical shield, and wherein the valley areas are disposed between adjacent the interlocked portions of the at least two layers of metal sheets which are interlocked.
