Abstract: A method of manufacturing a fiber reinforced metal matrix composite article, the method comprises forming a first metal component, forming a second metal component and forming at least one fiber preform comprising at least one metal coated fiber. The metal at least one first portion of the at least one metal coated fiber of the at least one fiber preform is bonded to the metal at least one second portion of the at least one metal coated fiber of the at least one fiber preform to hold the at least one fiber in position. The at least one fiber preform is placed between the first metal component and the second metal component. The second metal component is sealed to the first metal component, and heat and pressure is applied such as to consolidate the at least one fiber preform and to diffusion bond the metal on the fiber of the at least one fiber preform, the first metal component and the second metal component to form a unitary composite article. The bonding comprises ultrasonic welding.
