PROCESS FOR THE PREPARATION OF MOLDING OF WHISKERS USING COMPLEX MATERIALS

摘要

Disclosed in this invention is a method of preparing a whisker-preform comprising the steps of (a) uniformly dispersing a mixture of silicon microparticles and carbon fibers in the ratio of 4:1 to 8:1 into aluminium alkoxide solution; (b) filtering the dispersion obtained in step (a), dehydrating the filtered material, forming and drying the dehydrated material; and (c) heating the material dried in step (b) at a temperature in the range of 300 DEG to 400 DEG C.
