Purpose: The goal of this project is the optimization of manufacturing technology of the ceramic preforms based on Al2O3 powder manufactured by the pressure infiltration method with liquid metal alloy. Design/methodology/approach: Ceramic preforms were manufactured by the method of sintering of ceramic powder. The preform material consists of powder Condea Al2O3 CL 2500, however, as the forming factor of the structure of canals and pores inside the ceramic agglomerated framework the carbon fibers Sigrafil C10 M250 UNS were used. Then ceramic preforms were infiltrated with liquid EN AC - AlSi12 aluminium alloy. Stereological and structure investigations of obtained composite materials were made on light microscope. Findings: It was proved that developed technology of manufacturing of composite materials with pore ceramic Al2O3 infiltration ensures expected structure and can be used in practice. Practical implications: The developed technology allows to obtain method's elements locally reinforced and composite materials with precise shape mapping. Originality/value: The received results show the possibility to obtaining the new composite materials being the cheaper alternative for other materials based on the ceramic fibers.
