An X-Ray Micro Computed-Tomography System for 3-Dimensional Microstructure Characterization of Multifunctional Composites

Abstract : An X-ray micro computed-tomography system (Skyscan 1172) has been installed and operated successfully at UCLA. The system is used for non-destructive characterization of 3-D microstructures of multifunctional composites for advanced aerospace systems and is found to be a very powerful instrument for various composites. The composites and devices under study include graphite nanoplatelet (GNP) and carbon nanotube (CNT) composites, energy harvesting/storage composites, ink jet printed electrodes, and thin film batteries. The tomographic images can show agglomeration of nanoparticles such as GNPs and CNTs as well as microvoids. They can also show internal damages in thin-film solar cells and batteries.
