SiC particles are coated with multi-walled carbon nanotubes using a simple chemical vapor deposition process. This new type of micro/nanoscale hybrid reinforcement combines the characteristics of carbon nanotubes and the micrometer-sized SiC particles. Using this hybrid reinforcement in an epoxy composite produced a significant improvement in mechanical properties, attributed to the carbon-nanotube- reinforced interface between the epoxy matrix and the particles.
