This paper addresses an innovative composite material (CM)- syntactic foam prodecued out of metal powder (Fe), fly ash cenospheres (CS) and clay. Due to the low density of CS (were used as space holder, CS bulk density-0,38 g/cm3), the average density of these foams is about 2,6-2,9 g/cm3. It was found that CS undergoes phase transformation during thermal treatment at a temperature of 1200 C. Microstructural observations reveal a uniform distribution of CS and Fe particles in the composite. Compressive strength and friction coefficient of obtained Fe/CS CM are in the range between 149-344 MPa and 0,15-1,1, respectively. Dependence of compressive strength on firing temperature is demonstrated exhibiting the maximum at 344 MPa. Dependence of coefficient of friction on a material properties, obtained at different firing temperature exhibits the minimum value of 0,15 at the firing temperature of 1150 C. The obtained syntactic form was shown to be a candidate for wear resistant applications.
