Abstract
The 10 MW Neutral Beam Injection Test Stand of the Institute of Plasma Physics of Nagoya University was used to subject fine grain graphites (13 types), and 2-d (6 types) and 4-d (2 types) carbon/carbon composites to heat fluxes of 16–106 MW/m 2 for pulse durations of 50–950 ms. Graphites with a low coefficient of thermal expansion and a coarse microstructure had good resistance to crack initiation but worse erosion compared to fine microstructure graphites. The 2-d carbon/carbon materials suffered extensive erosion under heat fluxes incident perpendicular to their weave orientation, while moderate erosion was detected when the heat flux was incident parallel to the weave orientation. The 4-d carbon/carbon materials showed little erosion in any orientation. After testing, no fatal cracks or fractures were observed in any of the carbon/carbon composites.
