METHOD FOR MAKING AN ARM FOR A HINGED STRUCTURE SUCH AS A ROCKER ARM FOR AN AIRCRAFT LANDING-GEAR STRUCTURE |
摘要 |
The invention relates to a method for making an arm for a hinged structure such as an aircraft landing gear structure, this arm comprising a main body (30; 130; 230) extending in a longitudinal direction (AP; BP; CP), and including an interface (13; 113; 213) such as a yoke radially protruding from the main body, this method including the steps of: making an insert (11; 211) including a base (12; 212) carrying the interface; making a mandrel (10; 110) integrating the base of the insert so that a portion of the external surface of this mandrel is delimited by a portion of the external face (17; 217) of the base of the insert; applying one or more layers of reinforcing fibers (31; 131; 231) around the mandrel and over all its length, so that each layer has the interface (13; 113; 213) passing through it without covering the interface; injecting resin into the layer or layers of reinforcing fibers (31; 131; 231) and at the level of the area of contact (32) of these layers (31) with the external face (17; 217) of the base; and polymerizing the resin to bind rigidly the layers of reinforcing fibers and the base of the insert. |
