Abstract: The flexible deceleration brush de-rotation method is an existing contact active de-rotation technique for free tumbling targets in space. According to the technical requirements of the flexible brush tool for a certain type of deceleration brush de-rotation device, a kind of flexible thin rod of carbon fiber composites was designed. By carrying out finite element simulation analysis, the rationality of the structural design scheme was verified. Thin rod samples were prepared by rubbing-winding process. Randomly selected samples were tested for validation. The test results show that, both the bundling stiffness of 24 composite flexible thin rods and the maximum bending deflection of a single composite flexible thin rod meet the basic design requirements. The results of the simulation analysis are in accordance with the experimental results. This research work has laid the foundation for subsequent research into the application of the component on the deceleration brush de-rotation device.
