Abstract

An optical fiber grating multi parameter sensor for temperature and strain real time monitoring has been proposed. Based on a polyimide fiber Bragg grating (PFBG), the system can be used for high temperature (100 300 ℃℃) monitoring, except for common temperature ( 20~100 ℃℃) and strain monitoring in composites curing process simultaneously. The PFBG is embedded into composites for VARI (Vacuum Assisted Resin Infusion) curing process. The temperature and strain are calculated according to the central wavelength. Different materials and structures are u sed in this paper. The results provide references for curing process optimization and technological process improvement of composites curing process..
