METHOD FOR THE PRODUCTION OF COMPONENTS MADE OF CERAMIC-MATRIX COMPOSITE MATERIAL

Torna indietro

Abstract

A method for the production of components made of ceramic- matrix composite material, in the energy sector (burners, refractory shields for combustion chambers, parts for ovens and heating systems subject to thermal shock and high temperatures, with the need to support heavy mechanical loads), in the metal -casting industry (tubes for conveying molten metal), and in the space sector (thermal shields for re-entry vehicles); according to the method, a preform (6) for ceramic fibres is shaped and set in a draining mould (12), for example made of gypsum; the fibres of the preform (6) are impregnated with a suspension of ceramic powders, the liquid of which is drained by capillarity from the draining mould; simultaneously to draining, a suspension of ceramic powders (20) is infiltrated between the fibres of the preform (6) so as to fill the empty space left by the drained liquid; at the end of the steps of draining/ infiltration a body (21) is obtained with a solidified or compacted porous matrix, which is removed from the draining mould (12) and undergoes sintering.
