Abstract
A tube including at least one cylindrical element made of a pultruded fibrous material impregnated with a thermoplastic matrix, at least one additional fibrous reinforcement, partially or completely surrounding the cylindrical element(s), the fibers contained in the additional fibrous reinforcement being positioned along an axis different from the longitudinal axis of the cylindrical element, the total content of fibers of the tube being of between 40% and 70% by volume, with respect to the volume of the matrix and of the fibers contained in the tube.
Claims23
A tube comprising:
- at least one cylindrical element made of a pultruded fibrous material impregnated with a thermoplastic matrix,
- at least one additional fibrous reinforcement, partially or completely surrounding the cylindrical element(s),
- the fibers contained in the additional fibrous reinforcement being positioned along an axis different from the longitudinal axis of the cylindrical element,
- the total content of fibers of the tube being of between 40% and 70% by volume, with respect to the volumes of the matrix and of the fibers contained in the tube.
The process as claimed in claim 22, wherein said deposition is carried out under a certain mechanical stress so as to exert pressure on the cylindrical element.
