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.
Claims25
A flexible multilayer metal structure suitable for use as a heat shield comprising:
- metal layers, at least two of the metal layers being metal foil layers each having a thickness of 0.006 in. or less;
- wherein
- the layers being interlocked together to form a number of folds of the layers, the folds holding the layers together, at least some of the folds extending into non-edge portions of the multilayer metal structure, wherein the multilayer structure defines air gaps that aid in producing a heat shielding effect.
A method of forming a flexible multilayer metal structure suitable for use as a heat shield comprising:
- forming a stack of metal layers, at least two of the metal layers being metal foil layers each having a thickness of 0.006 in. or less;
- interlocking the metal layers to form a number of folds of the layers, wherein the interlocking step is such that the folds hold the layers together, and at least some of the folds extending into non-edge portions of the multilayer metal structure, and air gaps are defined in the multilayer structure.
A method of making a flexible multilayer metal structure suitable for use as a heat shield comprising;
- providing metal sheets;
- forming a stack of the 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. or less;
- and
- interlocking the metal sheets to form a number of folds of the layers, wherein the interlocking step is such that the folds hold the layers together, and at least some of the folds extending into non-edge portions of the multilayer structure, and air gaps are defined in the multilayer structure.
A flexible multilayer metal structure suitable for use as a heat shield comprising:
- at least two layers of metal sheets each having a thickness greater than 0.006 in.;
- wherein
- the two metal layers being interlocked together to form a number of folds of the layers, the folds holding the layers together, at least some of the folds extending into non-edge portions of the multilayer metal structure, wherein the multilayer structure defines air gaps that aid in producing a heat shielding effect.
