Abstract

A first-generation laboratory X-ray tomographic microscope is used to non-destructively 'section' a continuous, aligned-fibre SiC/Al metal-matrix composite (MMC). Damage in the MMC associated with mechanical deformation is the principal focus of the study. Two types of deformation are examined: wedge loading (with and without load) and three-point bending. Quantification of crack opening and fibre fracture detection is found to be practical down to one-tenth of a pixel in the reconstructed sections.
