Kompozit Malzemelerde Üretim Süreçlerinin Gözetimi için Fiber Optik Tabanı Sensör Sistemi Tasarım ve Analizi

Abstract

It is essential to monitor the behavior of composite materials during manufacturing process to ensure the high quality of manufactured materials. For this purpose, the use of optical fiber sensing, particularly the embedding of fiber Bragg grating (FRG) sensors into composite materials has been gaining growing popularity. In this context, we design a FBG-based alternative sensor interrogation system and completed the theoretical analysis for the prospect of providing the residual stresses appearing during fabrication process of composite materials. It has been also realized, in this paper, the preliminary experimental trials by monitoring FRG sensors embedded into fiber reinforced thermo-set composites for the purpose of process monitoring.
