Abstract
The Scanning Laser Acoustic Microscope (SLAM) has been used to detect and identify the geometrical configuration of void irregularity in epoxy resin bonded joints to ensure the integrity of such joints and to relate these defects to the joint strength. Practical problems were encountered in accurately defining the size and depth of voids resulting from imperfections during the bonding process. Aluminum and plastic samples with drilled holes of various geometries and shapes were tested using the SLAM. The data obtained from the SLAM are in the form of colored photos showing discrepancies in the samples, velocity pattern variation, and readings of the sonometer. Data obtained from various samples were analyzed to extract information regarding size, depth, shape, and position of the simulated defects in the samples.
In this paper, the experimental results obtained using the SLAM will be presented. A comparison between theoretical and experimental results is given. Practical problems encountered in the use of the SLAM are discussed.
