- Аннотация: This article describes the results of studies of the impact of the integration of fiber optic sensors (FOS) on the elastic-strength properties of polymer composite materials (PCM), produced by autoclave processing and vacuum infusion. Tensile tests were carried out on PCM specimens based on a unidirectional carbon tape and an epoxy polymer matrix with a unidirectional and quasi-isotropic installation of reinforcing filler. The obtained values of the variation coefficients of tensile strength for unidirectional laying without FOS were 6 %, with FOS - 7 %, for the case of quasi-isotropic stacking - without FOS - 9%, with FOS - 8 %. Tests for tensile and compression of carbon fiber specimens based on equal strength carbon fabric and epoxy polymer matrix were carried out. The experimental values of the coefficients of variation of the tensile strength of specimens without FOS were 5 %, with FOS - 6 %, for the case of compression without FOS - 9 %, with FOS - 8 %. Thus, it has been experimentally confirmed that the introduction of FOS does not lead to a decrease in the mechanical properties of carbon-reinforced plastics, which is explained by the low volumetric content of FOS in the material, as well as by the high adhesive properties of the FOS-PCM system, which ensure the combined work of the FOS with the material components.
