The present invention describes various methods for manufacturing gel composite sheets using segmented fiber or foam reinforcements and gel precursors. Additionally, rigid panels manufactured from the resulting gel composites are also described. The gel composites are relatively flexible enough to be wound and when unwound, can be stretched flat and made into rigid panels using adhesives.

A method of manufacturing a ceramic matrix composite component includes placing a first impregnated fiber layer on a surface, aligning a second impregnated fiber layer with the first impregnated fiber layer, and joining the first impregnated fiber layer with the second impregnated fiber layer at a plurality of discrete joining regions. The joining of the first and second impregnated fiber layers comprises transferring energy from at least one tool into the first and second impregnated fiber layers at the plurality of discrete joining regions.

A material for 3D printing is described. The material comprises a polymeric composition comprising a thermoplastic polymer; and from 50 to 99 wt. % ceramic particles comprising a metal, wherein at least 50% by weight of the particles have a diameter in a range from 10 to 100 μm; wherein the material has a dielectric strength of at least 5 kV/mm and/or a dielectric constant of at least 5.

A method of infiltrating a fiber preform comprises positioning an assembly in a process chamber, where the assembly includes a tool comprising through-holes, a fiber preform constrained within the tool, and a sacrificial preform disposed between the fiber preform and the tool. The sacrificial preform is gas permeable. The process chamber is heated, and gaseous reactants are delivered into the process chamber during the heating. The gaseous reactants penetrate the through-holes of the tool and infiltrate the sacrificial preform and the fiber preform. Deposition of reaction products occurs on exposed surfaces of the fiber preform and the sacrificial preform, and a coating is formed thereon. In addition, the sacrificial preform accumulates excess coating material formed from increased reactions at short diffusion depths. Accordingly, the coating formed on the fiber preform exhibits a thickness variation of about 10% or less throughout a volume of the fiber preform.

A method for injecting a loaded suspension into a fibrous texture having a three-dimensional or multilayer weaving includes the injection of a suspension containing a powder of solid particles into the volume of the fibrous texture. The injection of the loaded suspension is carried out by at least one hollow needle in communication with a loaded suspension supply device, each needle being movable in at least one direction extending between a first face and a second opposite face of the fibrous texture so as to inject the loaded suspension at one or more determined depths in the fibrous texture.

An electronic device housing, and an electronic device including the same are provided. The electronic device housing includes a substrate including glass, an insert portion which is bonded to the substrate at a surface of the insert portion, and at which a functional component of an electronic device having the electronic device housing is disposed, and an elastic layer which is between the substrate and the insert portion and extends along the surface of the insert portion.

A method for forming a ceramic matrix composite (CMC) component with an internal cooling channel includes partially densifying a first fiber preform to form a portion of a final ceramic matrix volume, machining a first channel into a surface of the partially densified first fiber preform, covering the first channel with a fibrous member to form a near net shape fiber preform with an internal passage formed by the first channel and the fibrous member, and densifying the near net shape fiber preform.

A hybrid sandwich ceramic matrix composite (CMC) may comprise a first facesheet, a second facesheet, and a core between and bonded to both of the first facesheet and the second facesheet. The first facesheet and the second facesheet may each include filaments in a ceramic matrix. The hybrid sandwich CMC may be configured for exposure to a thermal gradient in which the first facesheet is exposed to a higher temperature environment than the second facesheet. The first facesheet and the second facesheet may have at least closely matching coefficients of thermal expansion, and the first facesheet may have a higher compressive strength than the second facesheet.

A method of fabricating a ceramic component includes hot pressing a composite component with a glass powder / filler cover mixture to form a consolidated glass-based coating on the composite component.

The gas turbine combustor liner can delimit a combustion chamber, and have at least one monolithic ceramic block having a first face exposed to the combustion chamber and a second face opposite the first face, and a 3D fabric of ceramic fibers partially embedded inside the monolithic ceramic block, and partially extending outside the second face of the monolithic ceramic block, away from the combustion chamber.
