Fiberoptic sensors (FOS), can be either placed on material surface or then can be embedded into the material structure. Network of fiberoptic sensors within composite materials provides real-time information about any deformation in material during manufacturing process or material exploitation. Main advantages of fiberoptic sensors are their shape and structure which result in easy embedding, preserving at the same time composite material mechanical properties, which in turn makes them a reliable automatic system for long-term structure health monitoring. In order to increase material damage resistance during ballistic loading, thermoplastic reinforced composite materials were made. This article describes procedure of embedding fiberoptic sensors in laminar thermoplastic composite material, as well as damage investigation after ballistic loading. Damage inside the composite material was detected by observing intensity drop of light signal transmitted through the optical fiber network. Experimental testing was carried out in order to observe and analyze response of material under various load conditions.
