A composite structural laminate comprise two outer metal, e.g. steel, layers and an intermediate elastomer core, e.g. of unfoamed polyurethane. The elastomer has a modulus of elasticity of greater than about 250 MPa and tensile and compressive strengths of at least 20 MPa. The strength of the bond between metal and elastomer is at least 3 MPa. The composite structural laminate member acts a single member under load, buckling globally, not asymmetrically.

[ What is claimed is:] [1.] A structural laminate member comprising:a first metal layer having a first inner surface and a first outer surface;a second metal layer having a second inner surface, and a second outer surface, the second metal layer being spaced apart from said first metal layer, andan intermediate layer comprised of an elastomer located between and adhered to said first and second inner surfaces, said elastomer having a modulus of elasticity, E, greater than or equal to about 250 MPa and a ductility exceeding that of the metal layers.
