Process for obtaining ceramic composites from polu00ecmeros polissilanos or polissiloxanos, reinforcing fibers of cellulose, poliacrilonitrila,Of hu00ecbridos poliacrilonitrila and cellulose fibres, carbon fibres, carbon fibres and hu00ecbridos poliacrilonitrila, and fribas carbon and cellulose.That allows to obtain materials that may have applications in structural components or not.In contact with hot areas where the essential requirement is the resistance, thermo mechanical and wear and erosion.Said process is particularly defined by the fact that involve the manufacturing of ceramic composites with matrix polymers containing silicon impregnation precursors of silicon carbide or D.And oxicarbeto silicon and strengthening the basis of poliacrilonitrila fibers (Pan) or cellulose fibers (rayon), or hybrid fibers of poliacrilonitrila and cellulose, or carbon fibre.Or hybrid fibers of carbon and poliacrilonitrila, or hybrids of carbon fibers and cellulose, prepared in the form of a preform or prepregs.
