Patent

CA 2412683

This invention relates generally to the design and manufacture of high performance, composite, tubular structures. More specifically, the invention relates to a high performance, composite tubular structure that utilizes an integral pattern of ribs (620) on the internal diameter "ID" (408) or outer diameter "OD" (640) surface of the tube. The present invention provides high performance, composite, tubular structures that are both lighter and stiffer than conventional tubes. In general, the present invention incorporates features into the design of tubular structures, to greatly enhance performance. For example, in accordance with one preferred embodiment of the present invention, tubular structures are enhanced by incorporating small, stabilizing, raised ribs (620) on the ID of the tube.

L'invention concerne, de manière générale, la conception et la fabrication de structures tubulaires composites haute performance. Plus particulièrement, l'invention porte sur une structure tubulaire composite haute performance possédant un motif intégré de nervures sur la surface du diamètre intérieur (Di) ou du diamètre extérieur (De) du tube. Les structures tubulaires composites haute performance de l'invention sont, à la fois, plus légères et plus rigides que les tubes classiques. En général, cette invention présente des caractéristiques non classiques dans la conception des structures tubulaires, en vue de grandement améliorer leur performance. Selon un mode de réalisation préféré de l'invention, les structures tubulaires sont, par exemple, améliorées par introduction de petites nervures de stabilisation ménagées dans le Di des tubes.
