| titleOfInvention | Carbon fiber-reinforced cement material and manufacture thereof |
| abstract | PURPOSE: To obtain a sufficient reinforcing effect and a conductivity imparting effect by a small quantity of short fibrous carbon fibers by continuously changing the concentration of carbon fibers along the direction toward the other surface from one surface and forming a concentration gradient, in which concentration near one surface is thinned and concentration near the other surface is thickened. n CONSTITUTION: A carbon fiber-reinforced cement group material is manufactured by dispersing carbon fibers in a cement group matrix, and has a shape having at least one pair of opposed surfaces, and a concentration gradient, in which concentration is increased continuously from the surface 1 side with the concentration of carbon fibers is measured along the direction toward a surface 2 from a surface 1 in a cut surface cut by a virtual cutting plane line D-D' when the thickness of a member is comparatively thin is formed. When a distance from the surface 1 to the surface 2 is divided into three equal parts and each part is represented by a first layer, a second layer and a third layer, a reinforcing effect and a conductivity improving effect are displayed remarkably when the quantity of carbon fibers in the third layer is twice or more the quantity of carbon fibers in the second layer. n COPYRIGHT: (C)1992,JPO&Japio |
