Abstract

A method of preparing a beta titanium-composite laminate comprising providing a first layer of beta titanium alloy having a yield strength to modulus of elasticity ratio and adhering a first layer of composite having a strength to modulus of elasticity ratio to the layer of beta titanium alloy, thereby forming a beta titanium-composite laminate, where the yield strength to modulus of elasticity ratio of the first layer of beta titanium alloy matches the strength to modulus of elasticity ratio of the first layer of composite such that the first layer of beta titanium alloy will reach its stress limit and the first layer of composite will reach its stress limits at about the same total strain. Also, a beta titanium-composite laminate comprising a first layer of beta titanium alloy having a yield strength to modulus of elasticity ratio, and a first layer of composite having a strength to modulus of elasticity ratio adhered to the first layer of beta titanium alloy, where the yield strength to modulus of elasticity ratio of the first layer of beta titanium alloy matches the strength to modulus of elasticity ratio of the first layer of composite such that the first layer of beta titanium alloy will reach its stress limit and the first layer of composite will reach its stress limits at about the same total strain. Further, a structure such as an airplane part including a beta titanium-composite laminate according to the present invention.
