Epoxy resin composition

摘要

The invention relates to an epoxy resin composition containing (A) an epoxy resin, (B) a copolymer resin having an acid number of at least 280 prepared using an aromatic vinyl compound and maleic anhydride as essential starting components, and (C) dicyandiamide. Prepregs are produced therefrom by impregnating fibrous substrates with the epoxy resin composition. Laminated sheets can be produced by further processing the prepregs at elevated temperature and pressure.
