53,617 CAN/REG FABRIC-REINFORCED BONDING SHEET Abstract The bonding sheet of the invention eliminates the need to use two-part resin compositions for making electrically- insulated rail joints. The novel bonding sheet quickly and conveniently provides strong, permanent adhesive bonds between a pair of joint bars and the rails being joined. The novel bonding sheet comprises a reinforcing fabric saturated with a blend of 1,2-epoxy resin which softens at 50° to 110°C and a dianiline which melts at 50° to 110°C.
