Summary: The high-performance microcombustion of CWs/AP/CL-20 composite is achieved by utilizing a multi-channeled hierarchical porous structure of CWs for loading AP and CL-20. CL-20 serves as a heat/pressure loss compensate agent due to its high-energy density, fast energy release rate, and large amounts of gas release during combustion. Enhanced heat and mass transfer from the hierarchical porous structure and synergistic reactions between components at nanoscale result in promising micro thruster performance.
