A lightweight, high compression strength ultra high temperature ceramic corrugated panel with potential for thermal protection system applications

ZrB2-SiC-graphite ultra high temperature ceramic (UHTC) corrugated panel was firstly proposed and fabricated with potential application for sandwich structured thermal protection system. The compression properties of the as-prepared ultra high temperature ceramic corrugated panel were evaluated at 1600 degrees C in air. The compression modulus and strength of this ultra high temperature ceramic corrugate panel were 312 MPa and 17 MPa respectively. The design of corrugated panel exhibited an excellent combination of lightweight and excellent compression properties. This study would provide a novel concept of ultra high temperature ceramic corrugated panel for the design of ultra high temperature thermal protection system applications. (C) 2014 Elsevier Ltd.
