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.

Abstract: A sports bat such as used to play baseball or softball, comprising a shell which includes a first layer of titanium alloy-fiber reinforced composite laminate, a second layer of titanium alloy-fiber reinforced composite laminate and a core layer between the first layer and the second layer. Further, a method of making a bat comprising a shell which includes a first layer of titanium alloy-fiber reinforced composite laminate, a second layer of titanium alloy-fiber reinforced composite laminate and a core layer between the first layer and the second layer.

Abstract: A method of combining a beta titanium alloy with advanced carbon composites, the combination having a matched yield strength and modules of elasticity ratio. When the combination is adhesively bonded both parts will approach maximum yield strength and fail at a similar amount of total strain. The titanium and carbon composites are combined by first abrading the titanium to be bonded, coating the titanium with platinum, aging the titanium, spraying primer on the coated titanium, applying adhesive to the primer side of the titanium and then applying the carbon to the adhesive. This allows the carbon composite to bond securely to the titanium. This composite uses the best properties of each component, the combination having a better set of properties than either part.

Abstract: 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.

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.
