The composites were fabricated from agricultural waste of rice husk (RH) and industrial waste of carbon fiber (CF) ends. The powder-state RH mixed with chopped CF ends (0 to 40 mass%) was molded into a disk by means of hot pressing in an inert condition without using any binders, and then heated at high temperatures by using an electric furnace. The surface static and kinetic friction coefficients of the composites were evaluated under the contact with a SUS304 ball. The composite added with 20 mass% of chopped CF and heated to 1000℃ displayed the lowest static and kinetic friction coefficients, which were respectively 0.14 and 0.12. It was found that frictional properties of the composite were affected by thermal shrinkage of the matrix material derived from RH, the level of the added chopped CF, and crystallization of silica provided from RH.
