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. Combination of two different types of sheets is effective to provide both reinforcing and vibration damping effects.
