A flexible corrugated multilayer metal foil or metal sheet structure formed by corrugating a stack (10) of metal foil layers (1) and then compressing portions (26) of metal foil layers to fold the layers into overlapping relationships and to interlock the layers together. The corrugated interlocked multilayer metal foil sturcture is useful for heat and acoustic shielding in automotive, appliance, construction and other applications. The metal sheet or metal foil layers can contain embossments (7) or other shapes to provide gaps between portions of the layers (1) after corrugating and interlocking.
Structure de feuille métallique ou de tôle ondulée flexible que l'on forme en ondulant une pile (10) de couches de feuilles métalliques (1) et en comprimant des parties (26) de celles-ci pour les plier de sorte qu'elles se chevauchent et qu'elles se bloquent mutuellement. Ladite structure en feuille métallique ondulée à plusieurs couches se bloquant mutuellement est utile pour la protection thermique et acoustique dans l'automobile, les appareils électroménagers, la construction et d'autres applications. Les couches de tôle ou de feuille métallique peuvent présenter des bossages (7) ou autres de sorte que des espaces soient ménagés entre des parties des couches (1) après le formage d'ondulations et le blocage mutuel.
