A ceramic fibre reinforced metal rotor (10) is manufactured from a first metal ring (30), a second metal ring (32) and a plurality of fibre preforms (20). Each fibre preform (20) comprises a metal coated (18) ceramic fibre (14) arranged in a spiral. An annular groove (32) is formed in an axial face (34) of the first metal ring (30) and the fibre preforms (20) are arranged in the annular groove (32). An annular projection (38) is formed on an axial face (40) of the second metal ring (36) and two annular grooves (42,44) are formed on opposite radial sides of the annular projection (38). The second metal ring (36) is arranged such that the annular projection (38) is aligned with the annular groove (32) of the first metal ring (30). Heat and pressure is applied to axially consolidate the fibre preforms (20) and to bond the first metal ring (30), the second metal ring (36) and the fibre preforms (20) to form a unitary composite component. The grooves (42,44) allow axial movement of the projection (38) and control consolidation. <IMAGE> |
