Abstract: A ceramic matrix composite (CMC) material component is provided that includes a CMC material and an environmental barrier coating (EBC). The CMC material includes first fibers, a matrix, and at least one coefficient of thermal expansion (CTE) increasing additive. The first fibers include a first material having a first CTE value. The matrix includes a second material having a second CTE value. The at least one CTE increasing additive has a third CTE value. The EBC is disposed on at least one exposed surface of the CMC material and has a fourth CTE value. The third CTE value is greater than the first CTE value and the second CTE value, and the at least one CTE increasing additive is present within the CMC material in an amount that elevates a CTE value of the CMC material above the first CTE value or the second CTE value.

Abstract: An article includes a ceramic-based substrate and a barrier layer on the ceramic-based substrate. The barrier layer includes a matrix phase and a network of gettering particles in the matrix phase. The gettering particles have an average maximum dimension between about 30 and 70 microns. The gettering particles have maximum dimensions that range from about 1 to 100 microns, and a dispersion of barium-magnesium alumino-silicate particles in the matrix phase. A composite material and a method of applying a barrier layer to a substrate are also disclosed.

Abstract: An article includes a ceramic-based substrate and a barrier layer on the ceramic-based substrate. The barrier layer includes a matrix of SiO2 and a dispersion of silicon oxycarbide particles in the matrix. The silicon oxycarbide particles have Si, O, and C in a covalently bonded network, and a dispersion of barium-magnesium alumino-silicate particles in the matrix. The barium-magnesium alumino-silicate particles have an average maximum dimension that is between about 10-40% of an average maximum dimension of the silicon oxycarbide particles. A composite material and a method of applying a barrier layer to a substrate are also disclosed.

Abstract: A method of producing an enhanced ceramic matrix composite includes applying a tackifier compound to a fiber preform. The tackifier compound includes inorganic filler particles. The method further includes modifying the tackifier compound such that the inorganic filler particles remain interspersed throughout the fiber preform, and occupy pores of fiber preform.

Abstract: A process for densification of a ceramic matrix composite comprises forming a reinforcing ceramic continuous fiber stack having a central zone bounded by an outer zone adjacent; locating first particles within the central zone; coating the first particles and the ceramic fibers with silicon carbide through chemical vapor infiltration; locating second particles within the outer zone; coating the second particles and the ceramic fibers with silicon carbide through chemical vapor infiltration; forming the stack into a predetermined three dimensional shape; and densifying the stack.
