SiC/Cu composites were prepared by spark plasma sintering under different uniaxial pressure. X-ray diffraction (XRD), SEM techniques were used to characterize the sintered samples. It was found that higher pressure led to the transformation of Cu into Cu2O. The microhardness of the composites was improved by SiC reinforcements. The optimised pressure during the spark plasma sintering was about 50 MPa with the maximum hardness of 1.36 GPa.
