Hardened Composites, Refractories, and Transpiration Cooling II (RESEP II). Volume II, Part A. Task 10.3, Refractories Study.
Abstract
This report summarizes technical accomplishments during the RESEP II, Task 10.3 (Task 4) Refractories Study. During the program, a heat treatment study was conducted resulting in the selection of 2900 C as the optimum heat treatment for Poco AXF grade graphite. This material was characterized by mechanical, physical ablation and plate slap properties. A plug nose tip design using this material was generated and evaluated both analytically and experimentally. Design criteria and evaluation covered all re-entry environments both benign and hostile. Biaxial testing was conducted at room and elevated temperatures to determine both failure envelopes and stress-strain relationships. A study of an experiment to thermostructurally fail graphite by a well understood and controlled technique was conducted. Three-dimensionally reinforced carbon-carbon composite material was processed and characterized. (Author)
