Paper Abstract

SHM of composite structures is an emerging technology due to several benefits in terms of higher safety and security of human life, better material understanding, save money. Fiber-optic sensing technologies (FOS) are already proved to be reliable in the family of non-destructive testing (NDT) methods. The most frequently used are fiber-optic Bragg grating (FBG) sensors. However, several drawbacks of FBG cause a permanent improvement in the field of FOS. Within this paper the authors will confront the fiber-optic low-coherence interferometric (LCI) against FBG sensor taking into account experimental results simultaneously obtained by investigation of polyetheretherketon (PEEK) probe on stress by applying the three-point loading test.
