Method of improving crack resistance in fiber-metal-laminate structures

摘要

Residual stresses in a fiber-metal-laminate structure are altered by providing a fiber laminate substrate layer having first and second surfaces, and an outer metallic laminate layer having third and fourth surfaces; bonding together first and fourth surfaces; and peening the third surface, so that the fiber laminate substrate layer is subjected to residual tensile stresses and the outer metallic laminate layer to residual compression stresses. An independent claim is also included for a fiber-metal-laminate structure comprising a fiber laminate substrate layer and an outer metallic laminate layer.
