  • Patent number: 9090287
    Abstract: A method of manufacturing a structural support member for a vehicle includes forming a first portion, forming a second portion, and connecting the first portion and the second portion together. The first portion and the second portion may be formed from one of an aluminum material, a magnesium material, a cold-formable steel material, a glass fiber composite material, or a plastic material. The first portion and the second portion are connected together such that the second portion is disposed in a tensile loading condition in response to an impact load applied to the first portion. A laminate layer is attached to the second portion. The laminate layer includes an ultra high strength material having a yield strength equal to or greater than five hundred fifty (550) MPa. The laminate layer may include, for example, an iron based glassy metal foil or an iron based glassy metal foil fabric.
