Recent trend in aviation industry, weight reduction by using composite, such as a carbon fiber reinforced plastic (CFRP), has been positively promoted to save weight without sacrificing reliability. With increasing amount of usage of CFRP, improving quality and accuracy of CFRP drilling holes for a faster is one of the important requirements in order to ensure the safety of aircraft. To achieve the requirements, gyro driving grinding wheel system for CFRP drilling was proposed. For the grinding wheel, we have proposed functionally graded material (FGM) fabricated by a centrifugal mixed-power (CMP) method. The CMP method is one of the powerful and cost-effective processes to obtain composite materials by means of pressure impregnation. The mixed-powder method in addition to the centrifugal casting will make the fine particle dispersed FGM achievable. In this study, we attempted to fabricate Al/diamond and Cu/diamond composites by this method. Effect of casting temperature and metallic powder diameter on diamond abrasive powder dispersion was discussed.
