  • Patent number: 10173363
    Abstract: The present invention relates to a method for manufacturing a connecting rod including: a) manufacturing an inner body; b) adding one end of the inner body to the end of the reduced outer diameter of each end piece, said end of the inner body resting on the shoulder of the end piece; c) inserting a first portion of a second mandrel in the hollow cylindrical portion of each end piece and placing a driving bit at the free end of a second portion of the second mandrel; d) winding said pre-impregnated fibres onto the outer surface of an assembly consisting of the inner body, the end piece(s) and the second part(s) of the second mandrel(s) which are free of bits, said fibres then forming an outer body; e) after removing the bit(s), polymerising the inner body and the outer body to form a polymerised integral body; f) removing the second mandrel(s) and cutting the polymerised integral body to the required length.

  • Patent number: 9568041
    Abstract: The present invention relates to a method of manufacturing a connecting rod (1) by filament winding, said method comprising in particular: creating an internal body (5) by manufacturing a first component (6) by winding pre-impregnated fibers (17) around a mandrel (8) and removing the mandrel; manufacturing a second part (7); providing a shoulder (12) in the second part (7); assembling the first component with the second component (7, 22); creating an external body (14) by winding pre-impregnated fibers (17), identical to those used in the manufacture of the first component (6), around said internal body (5); creating a one-piece body (18) by polymerizing the assembly formed of the internal body and of the external body; and machining a fastening (19) at one end of the one-piece body; wherein the one-piece body (18) and the first fastening element (19) are made up of a one and same composite material.
