Notes:
By using the active filler controlled polymer pyrolysis, new and cost-effective compositematerials can be obtained. In this work, ceramic matrix composites were prepared by using thisprecursor route, using a polysiloxane network filled with metallic niobium and aluminum powdersas active fillers. The mixtures were blended, uniaxially warm pressed, and pyrolyzed in flowingargon at 1400 ºC. Porous ceramic preforms were infiltrated with a LZSA glass material, in order toimprove the density of a porous composite material. The properties of the pyrolyzed compositematerial and the effect of the LZSA infiltration on the Al2O3-NbC-SiOC ceramic compositematerial were investigated. The results have showed that the infiltration processes has improved thephysical and mechanical properties of the composite material
