Post-process interface development for metal-matrix composites

A composite component includes a reinforcement bonded to a base component by a bond formed by, or reinforced with, a localized coupling in the base component. The bond may be formed by ultrasonic additive manufacturing. The localized coupling may include a compression of the base component, a weld in the base component, or a heat affected zone of the weld. Where the bond is formed by the localized coupling, the localized coupling encompasses the reinforcement. Where the bond is reinforced with the localized coupling, the localized coupling may encompass the reinforcement, or be arranged at an inside radius of a turn in the reinforcement. The reinforcement results in the composite component having enhanced properties such as lower density, increased strength, stiffness, or energy absorption capabilities.
