Abstract
A method of manufacturing a fibre reinforced metal matrix composite article () comprises forming an annular groove () in the first metal component (), forming a second metal component () and forming a number of fibre preforms (). The fibre preforms () are placed in an annular channel () in a cassette (). The cassette () and the first metal component () are arranged such that the annular channel () in the cassette () is coaxial with and faces the annular groove () in the first metal component (). The fibre preforms () are moved from the annular channel () in the cassette () to the annular groove () in the first metal component (). The second metal component () is placed on the first metal component () such that the fibre preforms () are arranged between the first metal component () and the second metal component (). The second metal component () is sealed to the first metal component (). Heat and pressure is applied such as to consolidate the fibre preforms () and to diffusion bond the filler metal, the first metal component () and the second metal component () to form a unitary composite component.
