Reinforcing fibrous structure for a composite material and a part containing said structure

摘要

The part has two ends (10a) in which cylindrical free spaces (14) are arranged, and a body made of composite material which is realized from central and peripheral fibrous preforms (13, 11). The preforms are made by three dimensional weaving of strands of carbon fiber. The peripheral fibrous preform surrounds the central fibrous preforms in a manner to remain at the ends of the part, where the preform (11) is a strip whose ends are joined. The free spaces are adapted to receive an articulation axle of another part. Independent claims are also included for the following: (1) a landing gear comprising a strut including a lever (2) a method for manufacturing a mechanical part.
