Abstract
Optical fiber sensor is a kind of passive optical fiber device, which has the advantages of small size, high precision, strong anti-electromagnetic interference ability, easy wavelength division multiplexing, good compatibility with the structure to be measured, etc. It can measure various physical quantities such as strain and temperature, and it is easy to realize distributed measurement. With the development of solid rocket motor shell materials from metal materials to composite materials, it is also possible to embed optical fiber sensors for measurement. In this paper, the method and technology of embedding the optical fiber sensor into the composite solid rocket motor shell are designed, and the physical experiment is carried out. It shows that the method of embedding the optical fiber sensor into the composite solid rocket motor shell for strain testing is feasible, which can provide technical support for smart rockets and smart weapons.
