Abstract:
Equipment for the preparation of electric conducting composite samples by infiltration in a mould characterized in that it essentially comprises:a pressurization/infiltration chamber having at least one opening (39) to connect it by means of appropriate pipes with a vacuum line and a pressure line and devices for sealing both under vacuum and under pressure;a sample-holder (33), inside said chamber, made of a material with a high thermal conductivity with one or more seats in each of which a mould is housed consisting of:a chemically inert and thermally stable tube (31) made of a non-porous material;a plug (30), situated at one end of the tube, of a material which is different from the tube;a chemically inert and thermally stable spacer (32) of non-porous material, situated inside the tube in contact with the plug;means for creating a vacuum in the chamber;means for pressurizing the chamber;means for the thermal treatment of the sample-holder.
