A composite material of carbon/silica/carbon-fiber was fabricated from agricultural waste of rice husk and industrial waste of carbon fiber. Rice husk was pulverized by using a planetary ball mill. The powder of rice husk mixed with chopped carbon fiber (average length: 242μm, addition level : 10 mass%) was molded into a disk by means of hot-pressing in an inert condition without using any binders. A compression of 100 MPa was intermittently applied to the mixed which was heated from room temperature to 150℃, and then at 280℃. The molded was further heated to 300, 400, 500, or 1000℃ in an inert condition for sintering, providing a composite of carbon/silica/carbon-fiber. The composite added with 10 mass% of chopped carbon fiber and sintered at 300℃ displayed the highest compressive strength of 120 MPa and low bulk density of 1.25 g/cm^3.
