A notched Nextel 720/alumina (N720/A) +/-45 degree woven composite sample x-rayed during fracture testing. The surface in red corresponds to an evolving crack, while the blue streaks correspond to naturally occurring shrinkage cracks that form during the manufacturing process. This is a “model” material studied at Air Force Research Lab (AFRL) and was not manufactured by GE. (Photo credit: Michael Czabaj, Utah Composites Laboratory, University of Utah)
GE Aviation Delves Into Advanced Materials at the ALS
Scientific Achievement
GE Aviation is using ALS tomography capabilities to test ceramic matrix composite (CMC) materials, gain insights, and enhance engineering of their CMC-based jet engine components in commercial production.Significance and ImpactCMC-based components allow engines to run hotter, offering the economic and environmental advantages of higher fuel efficiency.Research DetailsThrough a collaborative ALS user program, GE Aviation is conducting synchrotron radiation micro-tomography experiments to study CMCs.GE uses mechanical testing to view CMCs at the sub-micron scale, gaining a better understanding of their features and the interaction between microstructure and damage evolution.
