Abstract (en)

[origin: WO2014118480A1] The invention relates to a method for producing, by pultrusion, a hollow main body (20) of a rotary transmission shaft made of a composite material, said method comprising: a step of impregnating the reinforcement (72); a step of placing a reinforcing fabric (82) around a pultrusion mandrel in order to envelope same, said fabric (82) comprising circumferential fibres arranged in planes orthogonal to a longitudinal shaft of the mandrel; and a step of depositing the impregnated reinforcement (72) around the reinforcing fabric (82).
