Filling type protective structure

The invention relates to the technical field of spacecraft protection, in particular to a filling type protection structure. The device is located between a buffer screen and a cabin wall of a spacecraft and comprises a filling layer and a porous supporting frame, the filling layer is arranged at the end, facing the buffer screen, of the porous supporting frame, the filling layer comprises ceramic fiber cloth layers and aramid fiber cloth layers which are alternately arranged, the ceramic fiber cloth layers are arranged in front, the aramid fiber cloth layers are arranged behind, and the adjacent fiber cloth layers are naturally attached in a suspended mode. The interface effect of the fiber cloth layer in the filling layer is better enhanced, the interface contact and action time is prolonged, the pull-up deformation constraint is reduced, and a better fragment cloud dissipation function is achieved. The filling layer is combined with the porous supporting frame, pulling and deformation of the filling layer
