The mechanical properties of ZrB2-30 wt-%SiC ultra high temperature ceramic composites have been studied. The composite was processed by hot pressing at 2100 degrees C, 30 MPa and 45 min dwell time to achieve a good densification. Young%26apos;s modulus, single edge V notch beam fracture toughness, hardness, stress-strain deformation, four-point bending strength and Weibull parameters were measured. Fractography and microstructure analyses of ZrB2-30 wt-% SiC ceramic composite were also performed.
