Abstract

A process for bonding at least two elements (10, 12) of which at least one is impregnated with a thermostable thermoplastic resin or mixtures of resins, characterized in that the elements are placed in contact by pressure members which are adapted also to transmit vibrations to at least one of the elements so as to obtain temperature rise by friction at the interface, to the operating temperature comprised within a shoulder (20), comprising a less rapid increase of shoulder corresponding to the passage from the solid to the liquid condition of the resin or of the mixture of resins.
