A method of manufacturing a fibre reinforced metal matrix composite article ( 10 ) comprises forming an annular groove ( 32 ) in the first metal component ( 30 ), forming a second metal component ( 36 ) and forming a number of fibre preforms ( 20 ). The fibre preforms ( 20 ) are placed in an annular channel ( 80 ) in a cassette ( 70 ). The cassette ( 70 ) and the first metal component ( 30 ) are arranged such that the annular channel ( 80 ) in the cassette ( 70 ) is coaxial with and faces the annular groove ( 32 ) in the first metal component ( 30 ). The fibre preforms ( 20 ) are moved from the annular channel ( 80 ) in the cassette ( 70 ) to the annular groove ( 32 ) in the first metal component ( 30 ). The second metal component ( 36 ) is placed on the first metal component ( 30 ) such that the fibre preforms ( 20 ) are arranged 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 ). Heat and pressure is applied such as to consolidate the fibre preforms ( 20 ) and to diffusion bond the filler metal, the first metal component ( 30 ) and the second metal component ( 36 ) to form a unitary composite component.
