Adhesive joint quality assessment via acoustic emission monitoring
The interfacial adhesion properties of adhesive joints were measured using acoustic emission techniques. The techniques used detected acoustic emission activity using a PAC LOCAN-AT instrument during the process of adhesive polymerisation. Three series of specimens were prepared: ideal, partially defective and fully defective. Nine experiments, three for each defect type, were carried out and a complete suite of acoustic emission parameters, as well as the temperature, were recorded during the polymerisation process. The results showed some correlation between the quality of bonding and characteristics of the resulting acoustic emission curves.
