A method of forming a part includes forming a glass-ceramic matrix composite material to form a pre-consolidated feedstock sheet with a pre-determined shape. The pre-consolidated feedstock sheet is sectioned into a first piece of pre-consolidated feedstock sheet and a second piece of pre-consolidated feedstock sheet. The first piece of pre-consolidated feedstock sheet and a second piece of pre-consolidated feedstock sheet are assembled with a second piece of pre-consolidated feedstock sheet to form a composite layup. The first piece of pre-consolidated feedstock sheet and the second piece of pre-consolidated feedstock sheet are joined by compressing the composite layup to form a glass-ceramic matrix composite part.

A reactor furnace for coating fiber tow includes an elongate reactor having a fiber tow inlet and a fiber tow outlet; a thermo-chemical reactor section positioned along the elongate reactor; a first microwave source for directing microwave energy along the reactor from a first end of the reactor toward a second end of the reactor; a second microwave source for directing microwave energy along the reactor from the second end of the reactor toward the first end of the reactor; a gas inlet upstream of the thermo-chemical reactor; and a gas outlet downstream of the thermo-chemical reactor.

An end effector for welding composite components includes an end effector housing and a welding member mounted to the end effector housing. The end effector further includes a leading roller mounted to the end effector housing forward of the welding member and at least one follower roller mounted to the end effector housing aft of the welding member. The end effector further includes at least one first cooling air jet positioned to direct a first stream of cooling air toward the at least one follower roller.

An acoustic liner includes a first face sheet, a second face sheet spaced from the first face sheet, and a plurality of sidewalls extending between the first face sheet and the second face sheet. The plurality of sidewalls defines a plurality of cells. Each cell of the plurality of cells defines a cavity between the first face sheet and the second face sheet. A bulk absorber is disposed within at least one cell of the plurality of cells. The bulk absorber further defines the cavity of the at least one cell of the plurality of cells. The first face sheet defines a plurality of apertures extending through a thickness of the first face sheet. Each aperture of the plurality of apertures is aligned with a respective cell of the plurality of cells.

A sensor array system includes a skin. The sensor array system includes a lattice network coupled to a portion of the skin. The lattice network includes a plurality of interconnects and a plurality of nodes. The plurality of nodes are respectively defined by an intersection of two or more interconnects of the plurality of interconnects. The sensor array system includes a first sensor electrically connected to the lattice network at a first node of the plurality of nodes.

A method of fabricating a glass matrix composite includes providing a fiber preform in a cavity of a die tooling, the fiber preform circumscribing an interior region; providing a parison of glass matrix material in the interior region, the glass matrix material having a first viscosity; introducing pressurized inert gas into the parison to outwardly inflate the parison against the fiber preform; and while under pressure from the pressurized inert gas, decreasing the first viscosity of the glass matrix material to a second viscosity. The pressure and the second viscosity cause the glass matrix material to flow and infiltrate into the fiber preform to thereby form a consolidated workpiece. The consolidated workpiece is then cooled to form a glass matrix composite.
