Nondestructive, Thermal, and Mechanical Properties Evaluations of Composite Heatshield Materials

Abstract

This program involves material property characterization of both Advanced Heatshield Concept Assessment (AHCA) and Advanced Heatshield Program (AHP) materials. The first phase of this work involves nondestructive testing (NDT) CHARACTERIZATION AND EVALUATIONS OF TENSILE, COMPRESSIVE, THERMAL EXPANSION AND THERMAL CONDUCTIVITY PROPERTIES OF ARCS AND PLATES OF VARIOUS AHP composite heatshield materials after simulated nuclear encounter by flyer plate impact. Physical and mechancial properties are presented as a function of the level of impact. A detailed discussion of the distribution of structure- change within the arcs is presented for all materials. The second phase of this work includes quality control NDT of rings, arcs, and discs of various AHCA composite heatshield materials and a more extensive NDT characterization of selected rings and arcs from the quality control group. The results of the quality control inspections are also used to select certain rings for application to underground testing.
