Patent

CA 2483034

A composite structural material suitable, for example, as a replacement for wooden boards, is disclosed. It comprises a dimensionally stable core material ensheathed in a dimensionally stable, laminar covering that is adherent to the core material. The laminar covering is comprised of at least one layer of parallel cords (19) bonded to at least one layer of a rigidified web material (10) selected from the group consisting of paper and cloth. Suitable core materials include polyurethane foam (38), optionally filled with particles (32) of granulated rubber, expanded perlite, expandable polymer beads, and/or glass microspheres. The parallel cords (19) preferably are supplied in the form of a strip of polyester cloth, as the warp cords thereof. The web material (10) preferably is kraft paper that is rigidified with an epoxy resin.

L'invention concerne un matériau structural composite que l'on peut utiliser, par exemple, pour remplacer des panneaux en bois. Ledit matériau comprend un matériau noyau de dimensions stables enveloppé dans un revêtement laminaire dimensionnellement stable qui adhère audit matériau noyau. Le revêtement laminaire est composé d'au moins une couche de cordons parallèles (19) collée à au moins une couche de matériau en bande rigidifiée (10) choisie dans le groupe formé de papier et de tissu. Les matériaux noyaux sont notamment de la mousse polyuréthane (38), éventuellement remplie de particules (32) de caoutchouc granulé, de la perlite expansée, des perles polymères expansibles et/ou des microsphères en verre. De préférence, les cordons parallèles (19) sont fournis sous forme de bande de tissu polyester, comme leurs cordons en chaîne. Pour le matériau en bande (10), on utilise de préférence du papier kraft rigidifié à l'aide d'une résine époxyde.
