We studied the influence of the stressed state of a flat polymer composite material (PCM) sample with an integrated fiber-optic sensor (FOS) on the shape and frequency representation of the recorded AE signals. Fiberglass samples were subjected to loading by static stepwise tension with a loading step of 2500 N. Acoustic emission was recorded by two types of sensors: a local piezoceramic AE transducer and the arm of a Mach–Zehnder interferometer, represented by an optical fiber glued into the surface of the sample. At each stage of exposure, AE signals were generated by a Hsu–Nielsen source. The influence of the stressed state of the sample on its characteristic of AE signal propagation and the influence of the deformed state of the water supply on its frequency response have been established.
