Abstract
A method for producing by pultrusion a hollow main body of a rotary movement transmission shaft made of a composite material, the method including: impregnating a reinforcement; arranging a reinforcing fabric around a pultrusion chuck to wrap the pultrusion chuck, the fabric including circumferential fibers arranged in planes orthogonal to a longitudinal axis of the chuck; and then depositing the impregnated reinforcement around the reinforcing fabric.

A method for producing by pultrusion a hollow main body of a rotary movement transmission shaft made of a composite material, the method comprising:
- impregnating a reinforcement with a resin, the reinforcement being made from plural unidirectional fibers;
- arranging a reinforcing fabric around a pultrusion chuck to wrap the pultrusion chuck, the reinforcing fabric comprising circumferential fibers arranged in planes orthogonal to a longitudinal axis of the pultrusion chuck;
- and then
- depositing the impregnated reinforcement around the reinforcing fabric such that each of the unidirectional fibers of the impregnated reinforcement is put into contact with the reinforcing fabric arranged around the pultrusion chuck.
