使用缠绕方法制作复合材料层板,将光纤布拉格光栅传感器埋入到缠绕复合材料层板中、铝板和缠绕复合材料板之间,监测整个固化历程,包括固化过程的温度变化,升温过程和降温过程的应变变化,比较不同部位的差异。结果表明：由于热力学性能不同,复合材料内部与界面之间在固化过程中存在着差异,使得两种不同的材料在固化后期存在分离现象,并释放了一部分应力。%The composite plate was prepared by filament wound method, and then the experimental data was provided for different materials in common use by FBG seusor-based monitoring common cure of composites and aluminum plate and deformation process under temperature load. FBG sensors were embedded to monitor the cure of filament wound tmidirectional laminate and the strain between composite and aluminum plate. The results show that there exist differences between the inner of composite and the interface of composite-aluminum plate during the curing course due to their different thermodynamic properties, accordingly, the two different materials will be detached during the final curing process and release certain stress.
