Summary

Fracture mechanisms of discontinuous carbon fiber reinforced glass-matrix composites were experimentally studied for specimens with and without thermal-shock induced damage. Matrix cracking due to thermal shock was observed using both optical and scanning acoustic microscopes (SAM). Tensile stress-strain behavior and acoustic emission (AE) properties during tensile tests were measured for specimens with and without thermal shock. Matrix cracking during tensile tests was microscopically observed using both replica and in-situ SAM technique to reveal the damage progress. Difference in fracture process between virgin and thermally-shocked specimens was identified, based on AE measurement, replica technique and in-situ SAM observation.
