Abstract

A composite jet engine compressor ring is made by casting a tape reinforced with ceramic fibers, winding the cast tape around a mandrel to form an unconsolidated ring, heating the ring to drive off binder, and pressing at a high temperature to form a unitary composite ring. Compression of the ring in an axial direction during hot pressing results in a desired axial spacing between adjacent fibers. The tape is preferably cast from a mixture of titanium base metal particles and a polyisobutylene binder dissolved in an organic solvent.
