ABSTRACT:
A beta titanium-fiber reinforced composite laminate comprising at least one layer of beta titanium alloy and at least one layer of fiber reinforced composite, wherein the layer of beta titanium alloy has a yield strength to modulus of elasticity ratio that is substantially similar to the strength to modulus of elasticity ratio of the first layer of fiber reinforced composite. Also, a method of preparing a beta titanium-fiber reinforced composite laminate comprising the steps of, first, providing a beta titanium alloy having a first yield strength to modulus of elasticity ratio; then, heating the beta titanium alloy at a first preselected temperature for a first preselected time to produce a beta titanium alloy having a second yield strength to modulus of elasticity ratio; and then, adhering a fiber reinforced composite having a strength to modulus of elasticity ratio to the beta titanium alloy to produce a beta titanium-fiber reinforced composite laminate; wherein the first preselected temperature and the first preselected time are preselected such that the second yield strength to modulus of elasticity ratio of the beta titanium alloy is substantially similar to the strength to modulus of elasticity ratio of the fiber reinforced composite.
