An attempt has been made to improve interphase strength of reinforcement and matrix by autocatalytic deposition route. The auto catalytic copper has improved the interphase strength which has been validated by radial crushing test as per ASTM 939-09. The ultimate failure load and the compressive strength of the composite has enhanced to an extent of 66.74% in comparison with uncoated reinforcement. The existence of copper on SiC reinforcement has been explained by SEM-EDAX analysis.
