Abstract

The present invention concerns an end-fitting (2) intended to constitute a spacer for a roller consisting of two concentric tubes (10, 11) of axis xx', comprising spokes (20) linking two inner (201) and outer (200) cylindrical parts, characterised in that a fluid circuit extending from the centre towards the periphery comprises a first circumferential groove (50) arranged in the inner cylindrical part (201) and a second circumferential groove (41) arranged in the outer cylindrical part (200), linked by at least one pipe (22). This end-fitting (2) helps reduce the weight of the roller by approximately 20%, assists in the balancing of the roller by ensuring the inside of the roller is accessible between the two tubes (10, 11) and allows easy, index-free assembly as a result of the circumferential grooves (41, 50). An end-fitting with spokes allows access to the inside of the roller when it is mounted, and thus both allows finer balancing than with solid end-fittings which require the outer tube to be pierced, and allows this balancing to be invisible from the outside of the roller.

Abstract

The present invention relates to a method for overmoulding a thermoplastic tip (4, 5) onto a hollow profile member (1) made of thermosetting composite and to an assembly including a thermosetting profile member (1) and a thermoplastic tip (4, 5), the method being characterised in that it comprises the following steps: machining the shape of the profile member (1) made of thermosetting composite on the injection region; positioning a cap (2, 3) in the profile member (1); thermally conditioning the profile assembly (1) and the cap (2, 3); injecting the tip (4, 5) with thermoplastic composite in order to create the junction of the profile member (1), the cap (2, 3) and the tip (4, 5).

IPC Classes  ?

Abstract

The invention relates to a method for manufacturing a part made of a composite material by pultrusion, the method consisting of manufacturing a continuous profile section (P) made of a composite material from a reinforcement (R) impregnated with a matrix and pulled through a die (10), which gradually shapes the composite material into the cross-section of the profile section (P) to be manufactured, the manufacturing method including at least three consecutive steps performed in the die (10): a first step of starting to shape the composite material, an intermediate step of starting to harden the matrix, and a final step of finishing the hardening of the matrix and finishing the shaping of the composite material, the manufacturing method being characterised in that vibrations are applied to the die during the first and/or final step, and in that no vibrations are applied to the die during the intermediate step. The invention also relates to a die for implementing said method, to a pultrusion manufacturing line including said die, and to a part made of a composite material obtained by said method.
