The first step experimental researches about embedded fiber Bragg grating (FBG) sensors network for health monitor of solid rocket motors (SRM) were presented in this thesis. In the experiment, the FBG sensors networks were embedded in composites plane with simulative delamination and scale SRM models. The results of the plane bend test indicated that damage could be identified by detecting concentration strain field, and the results of the scale SRM shells internal hydraulic pressure test indicated that the complex strain and deformation could be monitored by the sensors network, leading to the possibility to develop FBG sensors network systems for composites SRM health monitor. These researches will extend missile weapons reliability and safety in serving lifetime, enhance maintenance procedures to maximize serving time and improve reliability.
