Abstract
Acoustic emission baseline data was generated on fiberglass-epoxy composite specimens taken from booms of hydraulically operated aerial man-lift equipment. Acoustic emission signals were recorded while notched and notch-free specimens were tested in cyclic bending until failure. The transition to a load regime with no Kaiser effect was observed with an average K value of 0.58 measured for notch-free specimens. Frequency analysis of the stress waves caused by deformation of fiberglass specimens was helpful in determining appropriate frequency ranges for acoustic emission monitoring.Keywords
