Environmental effects on advanced fibre hybrid composites - an acoustic emission study

TL;DRAbstract

Hygrothermal effects on the failure mechanism of neat resin and simple and hybrid (permeable and/or impermeable) fiber composites have been studied using AE techniques. AE cumulative counts as a function of stress have been obtained for both dry and hygrothermally conditioned specimens. The experiments revealed a significant change in the failure process in these composites, in addition to the degradation in strength and stiffness properties.
