| Research Abstract |
Light-weight and high-strength eco-composite material was produced from rice husks and chopped carbon.fiber ends by means of a specified hot-pressing molding without using any binders. The relation between the manufacturing conditions and mechanical properties was clarified, the manufacturing conditions were optimized for attaining the superior mechanical properties. The composite which was produced from raw rice husk powder and 20 mass% chopped carbon fiber ends (average length : 0.24 mm), and was sintered at 300℃ showed the superior mechanical properties of bulk density 1.19 g/cm^3, Shore hardness 76 HS, bending strength 41 MPa, compressive strength 150 MPa, kinetic friction coefficient 0.22, and specific wear 2.6×10^<-9> mm^2/N.
