Acoustic Emission Monitoring and Destructive Testing of Glass Fibre Reinforced Plastic Bucket Truck Booms


The objectives of this study were to develop a larger data base on which to select acoustic emission (AE) criteria for predicting the serviceability of glass fibre reinforced plastic (GFRP) bucket truck booms and to determine the structural significance of visually detectable in-situ service defects such as cuts, cracks and impact damage. Six different GFRP booms which had been removed from service were mounted in cantilever and incrementally loaded to failure and periodically subjected to an ASTM F914 type test procedure. Data generated from the continuous monitoring of AE sensors mounted along the boom length included signal events, counts and amplitude. Felicity ratio and boom compliance were evaluated in order to obtain additional damage growth information.
