Abstract
A reinforced wall comprises a stiff substrate having a reinforcing laminate bonded to its inner surface. The reinforcing laminate includes an outer foil support and an expandable polymer foam material bonded to the foil support or backing. The polymer foam is disposed against the inner surface of the substrate and becomes intimately bonded to the inner surface upon activation and expansion of the foam material.
Claims29
A reinforced wall comprising a stiff substrate having an inner surface, a reinforcing laminate bonded to said inner surface, said reinforcing laminate comprising an outer support made of a foil material, an expandable polymer foam material bonded to said foil support and disposed against said inner surface of said substrate, said foam material being bondable to said inner surface upon expansion of said foam material, said laminate having outer edges, said laminate including a stiffening bead formed by said foil support and said foam material located generally centrally of said outer edges, said expandable polymer foam material being a material which upon expansion moves said foil material laterally away from said inner surface with said foil material spaced away from said inner surface, and said expandable foam material before expansion being bonded to and held by said foil material whereby said foil material and said foam material forms a coupled unit before and after expansion.
A reinforced wall comprising a stiff substrate having an inner surface, a reinforcing laminate bonded to said inner surface, said reinforcing laminate comprising an outer support made of a foil material, an expandable polymer foam material bonded to said foil support and disposed against said inner surface of said substrate, said foam material being bondable to said inner surface upon expansion of said foam material, both of said foil support and said foam material of said laminate being of corrugated shape to cause said laminate as a whole to be of corrugated shape along opposite outer surfaces of said laminate, said expandable polymer foam material being a material which upon expansion moves said foil material laterally away from said inner surface with said foil material spaced away from said inner surface, and said expandable foam material before expansion being bonded to and held by said foil material whereby said foil material and said foam material forms a coupled unit before and after expansion.
A reinforced wall comprising a stiff substrate having an inner surface, a reinforcing laminate bonded to said inner surface, said reinforcing laminate comprising an outer support made of a foil material, an expandable polymer foam material bonded to said foil support and disposed against said inner surface of said substrate, said foam material being bondable to said inner surface upon expansion of said foam material, said expandable polymer foam material being a material which upon expansion moves said foil material laterally away from said inner surface with said foil material spaced away from said inner surface, and said expandable foam material before expansion being bonded to and held by said foil material whereby said foil material and said foam material forms a coupled unit before and after expansion, including a fixture mounted to said inner surface of said substrate, said laminate being disposed in said fixture, one wall of said fixture being said inner surface of said substrate, said laminate before expansion being of substantially smaller volume than said fixture, said laminate substantially filling, said fixture after expansion with said foam material bonded to said inner surface of said substrate.
