(A) In a composite material comprising reinforcing fibres uniformly distributed in a metal or cermet matrix, the novelty is that the fibres are ceramic fibres which are sepd. or in cloth form and which are covered with a thin protective coating of material selected from carbon, boron and transition metal carbides, nitrides, borides, carbonitrides and oxides. (B) Prodn. of the composite material comprises coating the fibres with a protective coating, mixing the fibres with matrix powder, homogenising the mxit. in a liq. medium, shaping and sintering. |
