Abstract
A ceramic fibre reinforced metal rotor is manufactured from a first metal ring, a second metal ring and a plurality of fibre preforms. Each fibre preform includes a metal coated ceramic fibre arranged in a spiral. An annular groove is formed in an axial face of the first metal ring and the fibre preforms are arranged in the annular groove. An annular projection is formed on an axial face of the second metal ring and two annular grooves are formed on opposite radial sides of the annular projection. The second metal ring is arranged such that the annular projection is aligned with the annular groove of the first metal ring. Heat and pressure is applied to axially consolidate the fibre preforms and to bond the first metal ring, the second metal ring and the fibre preforms to form a unitary composite component. The grooves allow axial movement of the projection and control consolidation.
