Abstract: |
This study introduces the failure modes and factors of carbon fiber composited shell in solid rocket motor. Then it analyses the forming of stress convergence areas in vessel domes and the influences on the stress transferring, which due to the different toughness by different kinds of materials. Finally, the paper concludes the present situation and the research progress of compensation technology in domestic universities and institutes. |
