Light-weight and High-strength Eco-composite Materials derived from Rice Husks and Carbon.fiber Ends

以稻壳和切碎的碳纤维末端为原料，不使用任何粘合剂，通过热压成型生产出轻质高强生态复合材料。阐明了制备条件与力学性能之间的关系，并对制备条件进行了优化，以获得优异的力学性能。以稻壳粉为原料，以质量为20%的碳纤维端部（平均长度为0.24 mm）为原料，在300℃下烧结而成的复合材料具有良好的力学性能：堆积密度1.19 g/cm^3，邵氏硬度76 HS，抗弯强度41 MPa，抗压强度150 MPa，动摩擦系数0.22，比磨损2.6×10^<-9> mm^2/N。

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.
