A method for manufacturing a layered tile comprising a mutually connected ceramic tile and a concrete body, the method comprising the steps of applying an organic primer to a first surface of the ceramic tile, optionally positioning the ceramic tile in a mold, exposing the first surface, applying a concrete mixture on top of the tile's first surface, pre-hardening the concrete mixture for obtaining a green product, removing the product from the mold, and fully hardening the concrete for obtaining the layered tile.

A structured multi-phase composite which include a metal phase, and a low stiffness, high thermal conductivity phase or encapsulated phase change material, that are arranged to create a composite having high thermal conductivity, having reduced/controlled stiffness, and a low CTE to reduce thermal stresses in the composite when exposed to cyclic thermal loads. The structured multi-phase composite is useful for use in structures such as, but not limited to, high speed engine ducts, exhaust-impinged structures, heat exchangers, electrical boxes, heat sinks, and heat spreaders.

A method for manufacturing a sensor element that includes: a pair of electrodes; a ceramic layer having a hollow space that is to be an air introduction hole; and a first layer and a second layer stacked at both surfaces of the ceramic layer, One of the electrodes is in communication with the hollow space, The method includes: preparing an unsintered ceramic sheet, and a burn-out material sheet having a thickness different from that of the unsintered ceramic sheet, the burn-out material sheet having, in a plane orthogonal to the direction of an axial line O, a cross-sectional area substantially identical to a cross-sectional area of the pre-sintering hollow space; placing the burn-out material sheet in the pre-sintering hollow space; pressing the sheets so as to have an identical thickness; and burning out the burn-out material sheet.

The invention relates to a copper/ceramic composite comprisinga ceramic substrate which contains aluminum oxide, a coating which lies on the ceramic substrate and which is made of copper or a copper alloy, wherein the copper or the copper alloy has a particle size number distribution with a median value d.sub.50, an arithmetic mean value d.sub.arith, and a symmetry value S(Cu)=d.sub.50/d.sub.arith; the aluminum oxide has a particle size number distribution with a median value d.sub.50, an arithmetic mean value d.sub.arith, and a symmetry value S(Al.sub.2O.sub.3)=d.sub.50/d.sub.arith; and S(Al.sub.2O.sub.3) and S(Cu) satisfy the following condition: 0.7<S(Al.sub.2O.sub.3)/S(Cu)1.4.

A turbine engine component may comprise a Ceramic Matrix Composite (CMC) structure including a plurality of nominally dense plies, wherein each of the plurality of the nominally dense plies are bonded by at least one of a Field Assisted Sintering Technique (FAST), a Spark Plasma Sintering (SPS), or a localized heating at a bonding interface. The turbine engine component may include an airfoil extending between a first platform and a second platform, wherein the airfoil, the first platform, and the second platform define the CMC structure.

A method for fabricating a composite component for horology or jewellery including making a base from a first material, with a first visible apparent surface, and a first support surface; a structure from a second ceramic, or sapphire or at least partially amorphous material, with a second apparent surface and a second support surface, including a through bore machined over the entire thickness thereof; at least one insert made of a third material, for each through bore, and arranged to fit together in a complementary manner with this through bore; bonding this base and each structure to each other, with each first support surface and each second complementary support surface bearing against one another; securing each insert with its respective through bore.

A densified ceramic matrix composite (CMC) material densified CMC exhibits superior strength and toughness, relative to prior CMCs The material can be made by a process that includes impregnating a set of ceramic fibers with a non-fibrous ceramic material, resulting in a precursor matrix, stabilizing the precursor matrix, resulting in a stabilized matrix, and densifying the stabilized matrix using a frequency assisted sintering technology (FAST) process, resulting in the densified CMC material.
