ABSTRACT:
A part made of a resin-containing composite material, also having at least one insert made of a different material, is hardened by electron beam radiation in zones having a surface mass at the most equal to 4 g/cm.sup.2 and by X-radiation in zones having a surface mass above 4 g/cm.sup.2. The X-radiation, in doses up to 10 Mrad, is produced by action of the electron beam on a target placed between the part and the electron beam.
