By using the active filler controlled polymer pyrolysis, new and cost-effective composite materials can be obtained. In this work, ceramic matrix composites were prepared by using this precursor route, using a polysiloxane network filled with metallic niobium and aluminum powders as active fillers. The mixtures were blended, uniaxially warm pressed, and pyrolyzed in flowing argon at 1400 °C. Porous ceramic preforms were infiltrated with a LZSA glass material, in order to improve the density of a porous composite material. The properties of the pyrolyzed composite material and the effect of the LZSA infiltration on the Al2O3-NbC-SiOC ceramic composite material were investigated. The results have showed that the infiltration processes has improved the physical and mechanical properties of the composite material.
