Abstract

PURPOSE:To improve the strength of a mold and to prevent the occurrence of cracks by causing whisker to intervene in the gaps of the inorganic powder filler dispersed in resin. CONSTITUTION:A mold is composed of thermosetting resin with which whisker and inorganic powder filler are dispersively compounded. The whisker is composed of the needle crystal having the diameter of 0.1-1mum and the aspect ratio of 50-200, and silicon carbide whisker or silicon nitride whisker is used for said whisker. The inorganic powder filler is selected from alumina, silica, silicon carbide or reduced iron powder, etc. As the thermosetting resin, epoxy resin or polyurethane resin, etc. is used. A premixed material is formed by kneading the whisker with the thermosetting resin, and the inorganic powder filler is kneaded with the premixed material and then it is molded into a prescribed shape by casting after effecting deareation treatment. The whisker is added to the thermosetting resin at the ratio of 5-20pts.wt. of the whisker to 100pts.wt. of the thermosetting resin, and the inorganic powder filler is added to said resin at the ratio of 100-300pts.wt. of the filler to 100pts.wt. of the resin.
