Abstract

Traditional metal materials and fiber reinforced composites are unable to meet the requirements of lightweight and impact resistance of aerospace components and the advent of fiber metal laminates has solved this problem. Most of the existing researches on FMLs focus on the improvement of material system and impact properties, while little attention has been paid to the changes of stress and strain during the forming process. Moreover, most of the existing monitoring methods are not suitable for non-destructive monitoring of strain during the whole forming process. In this paper, a strain monitoring method based on Fiber Bragg Grating (FBG) and Thermocouple (TC) is proposed, which can be applied to the forming process of autoclave without destroying the original stress distributions and component shapes of the parts. The strain variation process during the curing of FMLs was monitored and analyzed by using FBG+TC, so as to establish theoretical model of forming process, propose strain monitoring method based on Strain Definition (SD) and analyze comprehensively the characteristics and applicability of the three methods.
