Nondestructive Evaluations of Composite Heatshield Materials before and after an Underground Nuclear Exposure
Abstract
Nondestructive evaluations were performed on various composite heatshield materials before and after underground nuclear exposure. Quality control nondestructive evaluations were used to select representative rings from a larger sample. Additional nondestructive testing and nondestructive mechanical (NDM) evaluations were used to characterize the selected rings before and after exposure. Improved methods of characterizing rings after exposure were developed and will be implemented in Carbon-Carbon Design Program. The materials evaluated included an angled, tape-wrapped carbon-phenolic (R6300); 3D carbon/quartz-phenolic 3DC/QP); 3D carbon-phenolic (3DCP); 3D carbon-carbon (3DCC); and felt carbon-carbon (felt CC). All materials were evaluated before underground exposure. After exposure the R6300, 3DCC, and felt CC were evaluated. In the follow-on program the two CC materials will receive further evaluations.
