Abstract
The invention relates to a method of fabricating a composite material connecting rod, the method comprising the step of cutting out a pattern presenting two opposite edges from a composite fiber fabric made up of a plurality of superposed primary plies that are bonded together in such a manner that the primary plies can slide relative to one another, rolling the pattern into a tube in such a manner that the primary plies slide relative to one another to give a chamfer shape to the two edges, and joining together the chamfer-shaped edges so that they overlap.

A method of fabricating a composite material connecting rod, the method comprising the step of cutting out a pattern presenting two opposite edges from a composite fiber fabric made up of a plurality of superposed primary plies that are bonded together in such a manner that the primary plies can slide relative to one another and wherein the pattern is cut out in such a manner that it presents at least two extensions that come to face each other when the pattern is formed into a tube, rolling the pattern into a tube in such a manner that the primary plies slide relative to one another to give a chamfer shape to the two edges, joining together the chamfer-shaped edges so that they overlap, forming a connecting means adjacent at least one of a first end of the tube and a second end of the tube, the step of forming a connecting means including separating the primary plies in the extensions from one another and inserting intermediate plies of composite fiber in between the primary plies, and diffusing resin into the fabric of the tube by resin transfer molding.
