Carbon-titanium composites
First Claim
1. A method of preparing a carbon-titanium composite comprising the steps of:
- (a) providing a beta titanium alloy having a surface with an area;
(b) coating the surface of the beta titanium alloy with a metal selected from the group consisting of platinum and the functional equivalent of platinum as a coating material, to produce a coated titanium alloy;
(c) heating the coated beta titanium alloy at a temperature for a time to produce an aged coated beta titanium alloy; and
(d) adhering a carbon composite having a strength to modulus of elasticity ratio to the aged coated beta titanium alloy;
wherein the heating step imparts to the coated beta titanium alloy a yield strength to modulus of elasticity ratio that is substantially similar to the strength to modulus of elasticity ratio of the carbon composite.

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.
