Abstract When the optical fiber is buried in the composite material, an eye-shaped interface is formed due to the difference in the direction of the lay-up layer with the composite material. The eye-shaped interface is now simplified to a circle by area equivalence, a strain transfer model is established, and the model is evaluated based on finite element analysis.The average strain transfer rate of the two interface models under tensile load is calculated by finite element software and compared with the experiments. The results show that: the average strain transmittance of the two interface models under simulated tensile load is compared with that of the ophthalmic model. The strain transfer rate of the interface model at each point agrees well, and the results of the finite element calculations match with the experiments. The simplified interface model can replace the eye-shaped interface model for strain transfer analysis.

Key words： interface fiber strain transfer tensile composite material
