Space-Age Ceramics Get Their Toughest Test Print
Tuesday, 11 December 2012 14:52

 

Advanced ceramic composites can withstand the ultrahigh operational temperatures projected for hypersonic jet and next generation gas turbine engines, but real-time analysis of the mechanical properties of these space-age materials at ultrahigh temperatures has been a challenge – until now. Berkeley Lab and UC Berkeley researchers have developed the first testing facility at ALS Beamline 8.3.2 that enables CT-scanning of ceramic composites under controlled loads at ultrahigh temperatures and in real-time.
