Abstract
According to the present invention there is provided a panel-reinforcing sheet material having a multi-layered structure consisting of a first layer, a second layer and, optionally, a third layer, the first layer consisting of a foamable composition comprising, as essential components, (A) epoxy resin, (B) a rubber elastomer or a halogen-free powder thermoplastic resin of 150 .mu.m or less in average particle diameter, (C) a plasticizer, (D) a high-temperature-decomposition type blowing agent and (E) a heat-activaiton type hardener for epoxy resin, the component (A)/component (B) weight ratio being 0.2-5, the second layer consisting of a cloth, and the third layer consisting of a thin metal film of 50 .mu.m or less in thickness. This sheet material has good adhesion to oily surfaces and, when subjected to blowing and hardening, gives a sheet of good heat resistance, and can therefore be suitably used for the reinforcement of vehicle outer panel before electrodeposition.
