Acoustic Emission of Graphite and Boron Fiber-Reinforced Aluminum Composites during Deformation and Fracture.
Abstract
Experimental acoustic emission techniques of sound detection and analyses of pulse rate and pulse count as a means of evaluating fiber-reinforced composites are discussed. Since the stress-strain relationship for the composite, before fracture, was also obtained using conventional mechanical tension test equipment, it was possible to detect that region (strain) where significant fiber fracture began for a particular composite specimen. The composite materials of interest included graphite fiber-reinforced aluminum alloy 7000, boron fiber-reinforced aluminum alloy 6061, and boron fiber-reinforced aluminum alloy 2024. (Author)
