Monitoring the curing process of epoxy adhesive using ultrasound and Lamb wave dispersion curves

Monitoring the stiffness of adhesives is a crucial issue when considering the durability and strength of adhesive joints. While there are many studies conducted on specimens made only from adhesive, the problem of curing of an adhesive film in real joints is moderately considered. This paper presents the monitoring of stiffening of epoxy adhesive using ultrasound. Ultrasonic pulse velocity method was firstly applied for monitoring of adhesive...
