As a raw material for composite materials, carbon fiber is known excellent in strength and durability. This paper deals with a development of a new comminution process of carbon fiber so as to obtain a method of preparing carbon powder having a higher strength. From the experimental results it was found that, for the 1st-stage communution, high pressure compression of bounded carbon fiber is a pertinent process and for the 2nd-stage comminution over the 1st-stage product, use of vibrating ball mill is found to be a suitable process. A summary of the experimental results is as follows : 1) The diameter of raw carbon fiber is about 5 μm ; 2) the size of the product of the 1st-stage comminution is about 12 μm, when the pressure per unit mass of sample is 0.7 ton/g ; 3) the mean diameter of the final product obtained by the 2nd- stage comminution by means of the vibrating ball mill is about 0.8 μm.
