Abstract

This article describes research on the creation of a SMART Layer that makes it possible to solve problems concerning the incorporation, protection, and determination of the actual site of fiber-optic sensors with Bragg gratings. Various configurations are considered for the creation and utilization of SMART Layers based on polyurethane, polyamide, and a reinforced polymer grid. We demonstrate the possibility and correctness of the decryption of the information obtained from fiber-optic sensors incorporated in a SMART Layer when samples with such layers undergo uniaxial stretching. We discuss how the actual site of various configurations of embedded SMART Layers can be determined by radiation methods of non-destructive testing. It is established that the prototypes of SMART Layers developed here make it possible to solve questions associated with variation of the placement of fiber sensors after structures are formed from polymeric composite materials. The advantages and disadvantages of various configurations of SMART Layers are described, along with the possibility of using them for various monitoring tasks.
