Disclosed are foam structures (1) with enhanced physical properties which can be used in the areas of packaging, athletics, water sports, and construction. Generally, the structures are laminated polymer foams that include a core (4) of a low density foam and one or more skins (6, 8) of relatively high density foam covering the core (4). The skins provide improved physical properties to the foam structures (1) by improving the flexural strength, resistance to bending, and resulting damage from bending in the laminated foam structure while modestly increasing the weight of the laminated structure (1).

L'invention porte sur des structures en mousse (1) dotées de propriétés physiques améliorées et pouvant être utilisées dans le domaine de l'emballage, de l'athlétisme, des sports aquatiques et de la construction. En général, lesdites structures sont des mousses polymères stratifiées comprenant un noyau (4) en mousse de faible densité et une ou plusieurs croûtes (6, 8) en mousse d'une densité relativement élevée recouvrant le noyau (4). Les croûtes confèrent des propriétés physiques améliorées aux structures en mousse (1) en renforçant leur résistance à la flexion, au pliage, et en réduisant les dégâts que provoque le pliage dans les structures en mousse stratifiées, tout en n'augmentant que dans une modeste mesure le poids de ladite structure stratifiée (1).
