Abstract
A material for reinforcing a panel or plate includes a first resin layer having a high tensile modulus of elasticity after hardening; a second resin layer having a low tensile modulus of elasticity after hardening; an expandable member disposed between the second resin layer side and the panel to be reinforced. The expandable member is narrower than the reinforcing resin sheet. The first and second resin layers are combined in an unhardened or semi-hardened state to form a reinforcing resin sheet. The expandable member expands into a bead-like projection when heated and then hardens. The edges of the reinforcing resin sheet extend beyond the edges of the bead-forming member or expandable member is such a manner that the second resin layer of the reinforcing resin sheet can be attached to the panel or plate.
