PURPOSE:To provide the subject composition excellent in stability, moldability, vibration-damping property, etc., by adding specified amounts of flaky, powdery and fibrous fillers to a resin component comprising an epoxy compound, a polyphenol and a specified urea derivative. CONSTITUTION:An epoxy compound (e.g., bisphenol A epoxy resin) is mixed with a polyphenol (e.g., bisphenol A) and a compound of the formula (wherein R<1> and R<2> are each a lower alkyl, X<1> and X<2> are each H, a halogen, a lower alkyl, an alkoxyl, an aryl or nitro), e.g., 3-phenyl-1,1-dimethylurea. 100pts.wt. obtained resin forming component is mixed with 50-500pts.wt. flaky filler (e.g., mica), at most 200pts.wt. powdery filler (e.g., ferrite) and at most 100pts.wt. fibrous filler (e.g., alumina fiber) to produce a composition for vibration-damping material. |
