An open cell reticulated foam structure having a MAX phase ceramic material infiltrated at least partially into the foam structure to produce the infiltrated product. The open cell reticulated foam structure can be shaped and sized to the final shape and size of the final product prior to infiltrating with the MAX phase ceramic material. Sintering of the MAX phase ceramic material can be done with pressureless sintering. The final infiltrated product can provide heat shielding to temperatures in excess of 2400° C.

In order to provide a thermal transport structure excellent in bendability, heat dissipation property, and lightweight property and also a thermal transport structure having a high reliability against vibrations and an excellent heat transport performance, used is a thermal transport structure (5, 201) including stacked graphite sheets (1, 213). This thermal transport structure (5, 201) includes a fixing portion (10, 202, 301) in which the stacked graphite sheets (1, 213) are fixed to each other;

and a thermally conductive portion (11, 203) in which the stacked graphite sheets (1, 213) are not fixed to each other.

The present disclosure is directed to an engine component for a gas turbine engine, the engine component including a substrate that includes a composite fiber and defines a surface. An energy harvesting fiber is positioned within the substrate.

A carbon-metal/alloy composite material includes a composition represented by (1-a)Sn.sub.1-xM.sup.1.sub.x+aM.sup.2+cC, wherein: M.sup.1 includes one or more transition metals, metals, or metalloids; M.sup.2 includes one or more transition metals, metals, or metalloids; x is 0≦x≦1; a is 0≦a≦1; and c is 0<c≦99. A method of forming the carbon-metal/alloy composite material includes the steps of dissolving one or more precursor materials in a solvent to form a solution; adding an organic carbon forming precursor to the solution to form a mixture; heating the mixture in an autoclave reactor for a prescribed period of time; separating solids formed from the mixture after the heating; washing the separated solids with a washing solvent; and heating the washed solids under a non-oxidizing atmosphere to form the carbon-metal/alloy composite material.
