Assembly comprising a tube and a sleeve

   
   

The invention concerns an assembly comprising a tube in composite material including carbon fibers embedded in a resin, an extremity of which is equipped with a sleeve in plastic material such as polyamide, optionally equipped with a jointing thread. According to the invention, the tube comprises at least one layer of composite material, and the sleeve is obtained by overmolding injection of material on the tube. Preferably, the composite material constituting the tube comprises two adjacent layers of carbon fibers embedded in carbon, the inner layer being a layer whose fibers are substantially longitudinal, whereas the outer layer comprises helically arranged fibers.

A invenção concerne um conjunto que compreende um tubo no material composto including as fibras do carbono encaixadas em uma resina, uma extremidade de que é equipado com uma luva no material plástico tal como o polyamide, equipado opcionalmente com uma linha articulando. De acordo com a invenção, o tubo compreende ao menos uma camada do material composto, e a luva é obtida overmolding a injeção do material no tubo. Preferivelmente, o material composto que constitui o tubo compreende duas camadas adjacentes das fibras do carbono encaixadas no carbono, a camada interna que é uma camada cujas as fibras sejam substancialmente longitudinais, visto que a camada exterior compreende fibras helicoidal arranjadas.
