Abstract
Ceramic matrix composite articles comprising a ceramic, glass-ceramic or glass matrix and a fiber reinforcement phase disposed within the matrix consisting of amorphous or cyrstalline inorganic fibers, wherein there is provided, on or in close proximity to the surfaces of the inorganic fibers, a layer of sheet silicate crystals constituting a sheet silicate interface between the inorganic fibers and the ceramic, glass, or glass-ceramic matrix. Optionally, the composition of the matrix may be the same as the sheet silicate interface so that the matrix provides the sheet silicate layer.
Claims11
A ceramic matrix composite article comprising (i) a matrix phase consisting essentially of a ceramic material selected from the group consisting of crystalline ceramics, glass-ceramics and glasses, and (ii) a fiber reinforcement phase consisting essentially of a multiplicity of amorphous or crystalline inorganic fibers disposed within the matrix phase, characterized in that
- a layer of sheet silicate crystals is provided on or in close proximity to the surfaces of the inorganic fibers, said layer constituting a sheet silicate interface between the inorganic fibers and the matrix phase.
A ceramic matrix composite article comprising (i) a matrix phase consisting essentially of a ceramic material selected from the group consisting of aluminosilicate glasses, lithium aluminosilicate glass-ceramics, and alkaline earth aluminosilicate glass-ceramics, and (ii) a fiber reinforcement phase consisting essentially of a multiplicity of amorphous or crystalline inorganic fibers disposed within the matrix phase, characterized in that
- a layer of sheet silicate crystals is provided on or in close proximity to the surfaces of the inorganic fibers, said layer constituting a sheet silicate interface between the inorganic fibers and the matrix phase.
