PURPOSE:To obtain the titled novel composition, containing short fibers treated with a titanate based coupling agent, a polyfunctional epoxy compound, phenolic novolak resin, etc., and having excellent mechanical strength, crack, heat and moisture resistance. CONSTITUTION:A composition consisting of (A) short fibers (preferably aromatic polyamide fibers) treated with a titanate based coupling agent (e.g. isopropyl triisostearoyl titanate, etc.), (B) a polyfunctional epoxy compound (preferably novolak based epoxy resin), (C) a phenolic novolak resin, (D) an inorganic filler (e.g. crystalline silica powder, etc.) and (E) a curing accelerator (e.g. 2- methylimidazole, etc.). Furtheremore, the amount of the blended short fibers is preferably 1-7wt.% based on the total weight of the components (A), (B) and (C).
