Abstract: The present invention is directed to SiC whisker and/or fiber reinforced glass-ceramic matrix composite articles wherein an alkaline earth aluminosilicate constitutes the predominant crystal phase. More particularly, the composite articles will consist essentially of 10-60% by weight SiC whiskers and/or 15-70% by volume ceramic fibers and the glass-ceramic matrix will consist essentially, by weight on the oxide basis, ofThe preferred predominant crystal phase is selected from the group of anorthite and its pseudo-binaries, with mullite, cordierite, barium osumilite, and albite solid solution.

Abstract: The present invention is directed to the production of SiC whisker- and/or fiber-reinforced, internally-nucleated glass-ceramic matrix composite articles consisting essentially of 0.5-60% by weight SiC whiskers and/or 15-70% by volume ceramic fibers substantially uniformly distributed in a glass-ceramic matrix consisting essentially, in weight percent on the oxide basis, of 16-20% CaO, 38.5-46% Al2O3, 35-42% SiO2, and up to 10% total of at least one nucleating agent in the indicated proportion selected from the group consisting of 0.1-3% CR2O3, 0.25-3% HfO2, 2-5% MoO3, 0.25-3% Nb2O5, 0.25-3% Ta2O5, 0.25-3% WO3, and 1-10% ZrO2, wherein Al2O3 is present in an amount which is at least 5 mole percent and up to 50 mole percent in excess of that present in stoichiometric triclinic anorthite, and wherein the predominant crystal phases in the glass-ceramic are triclinic anorthite and mullite and/or alpha -Al2O3. Up to 1.5% As2O3 may advantageously be included in the composition.

Abstract: This invention relates to the production of laminated structures consisting essentially of a light weight interior member prepared from a glass, glass-ceramic, or ceramic, an exterior member prepared from a glass, glass-ceramic, or ceramic, and a bonding member prepared from a glass, glass-ceramic, or ceramic. The light weight interior member may be composed of a porous body, a corrugated body, or a honeycomb body. In a preferred embodiment, at least one of said members is reinforced through the entrainment of ceramic fibers and/or whiskers. In the most preferred embodiment, each exterior and interior member is reinforced through the entrainment of ceramic fibers and/or whiskers and the bonding member is reinforced through the entrainment of ceramic whiskers.
