Low fracture resistance is one of the most serious limitations of ceramic materials. The new SiC fiber‐bonded ceramic presented here was developed to address this problem. The thermally conductive material is a candidate for such demanding applications as gas turbine engine hot section components, where its high‐temperature capability, high thermal conductivity, and low density make it very attractive for replacement of heavy metal super alloy components. Synthesized by hot‐pressing the material with the commercial name Sintered Tyrannohex consists of hexagonal columnar SiC fibers with a thin interfacial carbon layer between them.
