Method of manufacture of composite materials by deformations repeated and material thus obtained.

摘要

A method for the fabrication of composite materials by repeated mechanical deformations comprises the introduction of a sleeved sample (F1), the mechanical deformation of the sleeved sample (F2) with a predetermined reduction ratio and the elimination of the sleeve (F6) either mechanically or chemically prior to cutting (F3) of the deformed assembly and the re-assembly (F4) of the cut elements in a new sleeve. The cycle of deformation, elimination of the sleeve, cutting and re-assembly is repeated until the desired internal dimensions are achieved (F5). An Independent claim is included for the composite material obtained by this method of fabrication.
