Abstract
A flexible multilayer metal structure includes using multiple layers interlocked to form folds holding the layers together. These folds can extend into non-edge portions of the multilayer structure so that the multilayer structure defines air gaps that aid in producing a heat-shielding effect.
Claims20
A flexible multilayer metal foil structure comprising:
- at least two layers of metal sheets wherein the layers are metal foil each having a thickness of 0.006 in. (0.15 mm) or less;
- wherein
- the two layers of metal sheets are corrugated and nested together in a stack;
- and
- a portion of the corrugations of the stack is compressed to form interlocking folds of the layers.
A method of making a flexible multilayer metal foil structure comprising:
- forming a stack of at least two layers of metal sheets wherein the layers are metal foil each having a thickness of 0.006 in. (0.15 mm) or less;
- forming corrugations across the stack of metal sheets whereby the corrugations in the layers are nested in the stack;
- and
- compressing a portion of the corrugations in the stack of metal sheets to form folds and interlock the layers together.
A method of making a flexible multilayer metal foil structure comprising;
- providing individual corrugated metal sheets;
- forming a nested stack of said corrugated metal sheets where the stack comprises at least three layers of metal sheets wherein at least two of the layers are metal foil each having a thickness of 0.006 in. (0.15 mm) or less;
- and
- compressing a portion of the corrugations in the stack of metal sheets to form interlocking folds of the layers.
A flexible multilayer metal sheet structure comprising:
- at least two layers of metal sheets each having a thickness greater than 0.006 in. (0.15 mm);
- wherein
- the two layers of metal sheets are corrugated together in nested corrugations and a portion of the corrugations are compressed to form interlocking folds of the layers.
A method of making a flexible multilayer metal sheet structure comprising:
- forming a stack of at least two layers of metal sheets each having a thickness of greater than 0.006 in. (0.15 mm);
- forming corrugations across the stack of metal sheets whereby the corrugations in the layers are nested in the stack;
- and
- compressing a portion of the corrugations in the stack of metal sheets to form interlocking folds of the layers.
A method of making a flexible multilayer metal sheet structure comprising;
- providing individual corrugated metal sheets;
- forming a nested stack of said corrugated metal sheets where the stack comprises at least two layers of metal sheets each having a thickness of greater than 0.006 in. (0.15 mm);
- and
- compressing a portion of the corrugations in the stack of metal sheets to fold the layers in the corrugations into interlocking engagement.
