In the book chapter, the authors review results regarding the mitigating of the impacts of space small debris on composite overwrapped pressure vessels (COPV) by using fibre sensors monitoring and self-repairing materials. The small debris impact dynamic was detected and monitored with fibre Bragg gratings (FBG) sensors at very fast acquisition frequencies, up to 500 MHz (2 ns), measuring the variation of the total reflected signal by the FBG. The acquisition system was based on commercially available products.
