Application of acoustic emission to detect damage mechanisms of particulate filled thermoset polymeric coatings in four point bend tests

Significance of output:

Although acoustic emission (AE) technology has been extensively applied to the study of failure mechanisms in polymeric composite materials and metallic coatings few studies have been dedicated to polymeric coatings and no reports of AE of particulate filled polymeric coating materials were found in a literature survey conducted using ISI Web of KnowledgeSM. Thus four point bend tests were carried out on particulate filled polymeric coated samples, the acoustic emission technique being employed to examine in-situ cracking during the tests. The different failure modes of the coating material were correlated with the loading conditions and AE signals.
