METHOD FOR PRODUCING A MECHANICAL MEMBER FROM COMPOSITE MATERIAL, HAVING AN IMPROVED MECHANICAL PERFORMANCE UNDER TRACTION-COMPRESSION AND BENDING

摘要

The invention relates to a method for manufacturing a mechanical member in composite material, such as a connecting rod (19), comprising successive operations of applying layers of reinforcing fibres braided all about a mandrel, comprising, between two operations of applying layers of braided reinforcing fibres, a step: of placing at least one element formed of pultruded reinforcing fibres (14''), oriented longitudinally (AX); and of at least temporary attachment of each pultruded element (14'') to the last layer of braided reinforcing fibres, and in which a resin is then injected into the various braided layers before this resin is polymerized in order to form a rough connecting rod.
