Disclosed are a series of composite polymer composite structures formed by the coextrusion of at least two distinct polymeric compositions including a structural composition and a coating composition whereby the primary structural frame formed from the structural composition includes at least one, and typically a plurality, of longitudinal recesses or cavities. These recesses or cavities may, in turn, be filled with a third distinct polymeric composition that may include wood byproducts and/or a foaming or blowing agent.
La présente invention concerne une série de structures polymères composites formées par la coextrusion d'au moins deux compositions polymères distinctes contenant une composition structurale et une composition de revêtement, le squelette structural primaire formé à partir de la composition structurale comprenant au moins un et typiquement une pluralité d'évidements ou cavités longitudinaux. Ces évidements ou cavités peuvent, à leur tour, être emplis d'une troisième composition polymère distincte qui peut contenir des sous-produits du bois et / ou un agent moussant ou gonflant
