METHOD FOR MANUFACTURING AN ARM IN COMPOSITE MATERIAL COMPRISING A TRANSVERSAL BEARING DESIGNED TO RECEIVE A FIXED OR ROTATING SHAFT

摘要

The invention relates to a method for manufacturing an arm (16) in composite material, this arm comprising a main body incorporating a bearing (22) designed to receive a shaft passing through it transversely, this method comprising the steps of: manufacturing a hub (11) by winding reinforcing fibres around a generally tubular support (12); manufacturing at least one sleeve (14); attaching the hub (11) to one end of the sleeve (14) and transversely to the sleeve (14) in order to form a mandrel; applying one or more layers of braided reinforcing fibres (21) around this mandrel with a machine for braiding reinforcing fibres (19); injecting and polymerizing resin into the layer or layers of braided fibres (21). The invention applies notably to an arm forming an undercarriage rocker arm of an aircraft.
