PURPOSE:The titled resin or casting, providing a cured material having improved crack resistance, low shrinkage, thermal conductivity, and fluidity, comprising an epoxy resin, a curing agent, fibers having specific diameters and length, and inorganic powdery granule having specific particle diameters. CONSTITUTION:The aimed resin composition comprising (A) 100-vol.pts. epoxy resin (e.g., glycidyl ether type epoxy resin) and curing agent (e.g., acid anhydride, amine, etc.) and (B) 90-200vol.pts. fibers having 3-20mu, preferably 9-13mu diameters, and 3-1,500mu, preferably 10-1,000mu length, and inorganic powdery granule (e.g., silica,l alumina, talc, etc.) having 10-50mu average particle diameter. |
