Damage Location in Thick Composite Material Based on Acoustic Emission and Wireless Nodes

Abstract : This investigation is studying the behaviour of a bespoke wireless impact locator design for monitoring structures against any kinds of impacts. The device performance was evaluated against its location repeatability, its ability to last the required service life, its power consumption and its wireless range. The main variables in this investigation were the sensor sensitivity, the wireless node data repeatability and the power supply output voltage. The investigation identified which power source to be used, what is the strategy to determine the remaining power life, as well as the feasibility to use such technology for impact location.
