Abstract
The invention discloses a metal stiffener composite article comprising a reinforcing resin solution of an elastomer, a thermosetting resin and a thermosetting resin curing agent formed into strips and contacted with a porous reinforcing layer. The reinforcing resin solution being thermodynamically unstable such that a thermosetting rich phase separates from the solution and forms a layer upon the surface of the solution impregnating the porous reinforcing layer.
