A method of manufacturing a fibre reinforced metal matrix composite article

摘要

A method of manufacturing a fibre reinforced metal matrix composite article (10), the method comprises forming a first metal component (30), forming a second metal component (36) and forming at least one fibre preform (20) comprising at least one metal coated (18) fibre (14). The metal (18) at at least one first portion (70) of the at least one metal coated (18) fibre (14) of the at least one fibre preform (20) is bonded (74) to the metal (18) at at least one second portion (72) of the at least one metal coated (18) fibre (14) of the at least one fibre preform (20) to hold the at least one fibre (14) in position. The at least one fibre preform (20) is placed between the first metal component (30) and the second metal component (36). The second metal component (36) is sealed to the first metal component (30), and heat and pressure is applied such as to consolidate the at least one fibre preform (20) and to diffusion bond (62) the metal (18) on the fibre (14) of the at least one fibre preform (20), the first metal component (30) and the second metal component (36) to form a unitary composite article (10) The bonding (74) comprises ultrasonic welding.
