Application of Fiber Bragg Gratings for Composite Rocket Engine Housings Monitoring

We report on a fiber Bragg gratings application for composite rocket engine housings monitoring. A prototype ring rocket engine housing made of four organoplastic layers with fiber Bragg gratings embedded was produced with wet winding and investigated. Results of the ring housing deformation simultaneous monitoring with fiber sensors and strain gauges with loading it up to 30 kN are demonstrated and compared.
