RESEARCH OF THE INTEGRATED FIBER-OPTIC SYSTEM FOR THE DIAGNOSIS OF CARBON FIBER REINFORCED PLASTIC AFTER THE IMPACT OF TECHNOLOGICAL MOLDING MODES
(pp. 42-49)

Abstract. This article describes results of studies on the preparation of fiber-optic sensors based on Bragg gratings for integration into carbon fiber reinforced plastics for the creation of a built-in non-destructive testing system. It was found that to increase the temperature resistance of sensors intended for integration into carbon plastic, it is advisable to subject the unstable part of the induced refractive index of the sensitive element to the controlled thermal action. It has been experimentally shown that the built-in fiber-optic diagnostics system remains fully operational after the impact of the technological molding modes of CFRP and can use as an effective tool the built-in control of the technical state of composite structures.

Keywords: built-in non-destructive testing, fiber-optic system for the diagnosis, fiber Bragg grating, carbon fiber reinforced plastic, technological molding mode.
