Non-destructive evaluation of adhesive bond strength in laminated wood beams

Research output: Contribution to journalArticlepeer-review

Abstract

Acousto-Ultrasonic (AU) non-destructive evaluation of laminated wood beams has been conducted to evaluate the adhesive bond strength between two layers using the stress wave factor (SWF) measurement technique. Wood beam specimens with different levels of adhesive bond strength were manufactured and tested using the acousto-ultrasonic stress wave factor approach. The strength of the laminated wood beam specimens was then evaluated using the commonly used destructive shear strength test method. It was observed that higher values of the SWF measurements correspond to higher values of the shear strength test data. Therefore, these results show that the acousto-ultrasonic approach has the potential of being used in quality assurance of the adhesive bond strength during the manufacturing process.
