A composite material structure of fibers joined by a resin matrix includes one or more regions provided at least partially with a covering consisting of an external metal mesh embedded in the resin matrix as last layer of the composite structure. In particular, in the cycle field it is possible to obtain, for example, handlebars (M) provided with two lateral meshes (T) in the clamping regions for the clips (S) of the brakes/gears assemblies (G) and a central mesh (T') in the clamping region for the connector (C) joining the handlebars (M) to the connecting element (A) to the fork (F), also these elements being provided with similar meshes (T', T') arranged on the contact surface of the clamping regions. In this way there is eliminated, or at least greatly reduced, the risk of failure in a clamping region thanks to the presence of the external metal mesh (T, T', T') which protects the underlying composite material. |
