  • Patent number: 4559252
    Abstract: A reinforcing combination is useful to reinforce plate metal which comprises a pressure-sensitive adhesive sheet formed from a sheet-like substrate comprising asphalt, rubber, and a filler and having a pressure-sensitive adhesive layer on one surface thereof; and a thermosetting sheet formed from a sheet-like substrate comprising polyvinyl acetal, monomeric diallyl phthalate, a filler, and at least one additive, and having a reinforcing fiber layer on one surface and a pressure-sensitive adhesive layer on the other surface thereof; wherein said thermosetting sheet at one edge partially overlaps said pressure-sensitive adhesive sheet with the pressure-sensitive adhesive layer of the former in contact with that surface of the latter which is remote from its own pressure-sensitive adhesive layer. A reinforcement configuration is provided by attaching the components of the reinforcing combination in assembly or separately followed by heat curing.
