Abstract: A self-adhesive prepreg comprising a fibre reinforcement layer having a first side and a second side, wherein the first side of the fibre reinforcement layer has been pre-impregnated with a self-adhesive (i.e. adheres to metal) resin composition. The self-adhesive prepreg may be used as a structural reinforcement and is especially adapted for direct bonding to oily steel or galvanized steel in the automotive, aerospace and other sheet metal fabrication industries. The resin component is ideally based on an aromatic epoxy resin.
