This work deals with the evaluation of ceramic-fiber reinforced plastics, as a grinding tool for various work materials. The composites were manufactured by mixing continuous alumina-fiber of definite diameters and thermosetting resin as a bond material. The characteristics of FRP tool as a grinding tool (volume fraction of fiber : 60%, fiber diameter : 10-25μm) are as follows : It is strong but fairly flexible so that it does not break up during use. The sharp edge of the tool does not rapidly lose its shape. The evaluation is performed in testing the composites with fibers of various different diameters from 10 to 25μm. The wear of the work and the composites and the surface finish of the work materials were evaluated.
