Abstract:Ceramic matrix composites consisting of mullite and 3Y-TZP containing alumina platelet reinforcements were fabricated by suspension processing and pressureless sintered. The effect of the matrix on the microstructural development in the presence of alumina platelets were characterized. A systematic study of the effect of platelet sizes in the ranges 3-5, 5-10, 10-15 and 15-25 microns on the green and fired microstructures in 3Y-TZP composites were determined using porosimetry and electron microscopy. The mechanical properties of the composites such as fracture strength, fracture toughness and high temperature microhardness as a function of platelet size and volume fractions were determined.
