Measurement of strain and temperature by fiber-optic sensors embedded into samples manufactured by additive technology

Le résumé fourni par la source

The paper demonstrates the possibility of using embedded point and distributed fiber-optic sensors to register data on the mechanical state of structures made by fused deposition modeling from thermoplastic materials. The performance of two types of fiber-optic sensors was demonstrated at the stage of sample fabrication. Uniform strength beam was taken as a sample. Temperature and strain were continuously recorded using the embedded fiber-optic sensors during the sample fabrication. Based on the readings of point and distributed fiber-optic sensors, graphs and surfaces of strain and temperature distributions along the length of the sample over time are presented. These parameters allow further evaluation of the inhomogeneity of strain and temperature distribution along the sample. Comparison of the experimental data obtained from two types of fiber-optic sensors during the sample fabrication was carried out.
