The Study of the Internal Curing Technology of Filament Wound Composite Based on Fiber Bragg Grating Detection

摘要

At present,only the temperature of external surface of the filament wound composite and the core mode can be detected in the curing process which is developed by experiencing many times,and the change of the internal parameters is not available. Based on the glass fiber pipe production line as the experimental platform,the paper suggests that the fiber grating sensors be embedded fiber composite materials at different levels when winding and the multipoint detection be performed in the internal curing process. The comparison analysis of the plotted curves for data collected from different points shows that the method is reliable to improve production efficiency and promote the automation of intelligent control.
