Abstract

We have previously reported a novel Fiber Optic Acoustic Emission Sensor (FOAES), which was specially processed based on fused-tapered optical fiber coupler. The FOAES was packed with silica capillary tube so that it could be embedded in damage monitoring of composite materials. But the linear damage location of acoustic emission using double sensors had not been tried. In this paper, linear damage location experiments with double sensors were tested on aluminium plate and composite plate. The test results showed that linear damage position was identified within ±6.25 mm on aluminium plate and ±4.84 mm on composite plate.
