A composite fiber structure (10) has fiber inserts with different materials or structures (13 through 17) and a ceramic matrix. The fiber structure comprising the fibers inserts is impregnated with the matrix material by liquid phase or gas phase infiltration, optionally after a prior treatment of the composite with a liquid polymer material. The fiber inserts may be of carbon, silicon carbide or alumina fibers, e.g. in fabric form, and the matrix may be of silicon carbide, alumina or mullite. The manufacture of components for a jet engine air intake, pumps and an injection molding machine, as well as brake discs, is described. <IMAGE> |
