THE POSSIBILITIES OF CONTROLLING EXTERNAL MECHANICAL INFLUENCES BY A FIBER-OPTIC DIAGNOSTIC SYSTEM EMBEDDED INTO CARBON FIBER REINFORCED PLASTICS OF DIFFERENT TYPES
(pp. 38-47)

Abstract. The estimation of working capacity and results of the control by the integrated fiber-optic system of diagnostics of CFRP samples on the basis of polymer matrices and reinforcing fillers of different types at shock impact, tests on the residual compressive strength after impact, long-term strength, low cycle and high-cycle fatigue are given. The ability of the sensor system to record the fact, determine the local impact zone and the occurrence of delamination, confirmed by the results of ultrasonic non-destructive testing, to maintain efficiency and confidently record data under static and cyclic loads is confirmed.

Keywords: fiber-optic system of diagnostics, fiber optic sensor, fiber Bragg grating, carbon fiber reinforced plastic, non-destructive testing, shock impact, long-term strength, low-cycle fatigue, high-cycle fatigue.
