Characterization of acoustic emission signals from particulate filled thermoset and thermoplastic polymeric coatings in four point bend tests

Characterization of acoustic emission signals from particulate filled thermoset and thermoplastic polymeric coatings in four point bend tests
Characterization of acoustic emission signals from particulate filled thermoset and thermoplastic polymeric coatings in four point bend tests
Four point bend tests were conducted on two previously characterized particulate filled thermoplastic and
thermoset polymeric coatings, the acoustic emission (AE) method being utilized to monitor the damage
progress during the tests. Different damage mechanisms operating in the polymeric coatings can be
recognized by the different amplitude range of the AE signals emitted. AE can be used to assess the relative
strength of particle/matrix bonds in particulate filled polymeric coatings.

Highlights

* Damage mechanisms in the particulate filled polymeric coatings can be distinguished from the AE signals.
* AE can be used to assess the relative strength of particle/matrix bonds in particulate filled polymeric coatings.
* No sudden load drop is associated with the formation of cracks in the coating during the elastic deformation of the steel substrate.

Abstract

Four point bend tests were conducted on two previously characterized particulate filled thermoplastic and
thermoset polymeric coatings, the acoustic emission (AE) method being utilized to monitor the damage
progress during the tests. Different damage mechanisms operating in the polymeric coatings can be
recognized by the different amplitude range of the AE signals emitted. AE can be used to assess the relative
strength of particle/matrix bonds in particulate filled polymeric coatings.

Highlights

* Damage mechanisms in the particulate filled polymeric coatings can be distinguished from the AE signals.
* AE can be used to assess the relative strength of particle/matrix bonds in particulate filled polymeric coatings.
* No sudden load drop is associated with the formation of cracks in the coating during the elastic deformation of the steel substrate.
