Abstract

Thoria and magnesia bodies were developed for use in metal-ceramic composites. Good thermal shock resistance was imparted to these bodies through control of particle size distribution. Magnesia was sintered at 2200F and thoria at 2800F. Plasma and oxyacetylene torch tests developed to evaluate these materials and similar zirconia composites showed that magnesia and zirconia can be used to 4600F and thoria to 5400F. A magnesia foam backing was developed for use with composites to reduce heat transfer to the substructure with a minimum gain in overall weight. Platinum and Inconel honeycomb were selected for use as a metal reinforcement for these bodies to produce material systems suitable for use in high heat flux applications such as the nose cap of a glide re-entry vehicle. Leading-edge configuration samples prepared from magnesia with Inconel honeycomb reinforcements were fabricated.
