               吸收动能的能力约为航空铝板的一半;但其抗爆性能显著优于航空铝,在航行任务中更有助于保证飞行器的安全。

               Abstract:  In response to the research demand for the impact resistance of carbon fiber-reinforced polymer (CFRP) laminates
               commonly used in aircraft, spherical fragment penetration and static blast tests were conducted on T800/3200 CFRP laminates,
               with CT scanning technology and damage assessment theories employed for further analysis. The damage characteristics and
               performance of T800/3200 CFRP laminates under two typical loads-fragment penetration and explosive shock waves-were
               investigated  and  compared  with  2024-T3  aluminum,  a  material  widely  used  in  the  aviation  manufacturing  industry.  Two
               control groups were established: tungsten fragments impacting aerospace aluminum plates and tungsten steel fragments striking
               CFRP  laminates.  Impact  velocities  and  residual  velocities  were  precisely  measured  using  high-speed  photography.  During
               fragment penetration tests, relationships among incident velocity, residual velocity, and energy absorption were analyzed based
               on the Recht–Ipson ballistic limit model. The internal damage morphology of CFRP targets was examined in detail using high-
               resolution CT scanning technology to characterize delamination patterns and progressive failure across different depths and
               plies.  In  blast  tests,  the  damage  morphology  and  maximum  deflection  of  target  plates  were  systematically  observed  and
               recorded.  The  blast  resistance  of  CFRP  laminates  and  aluminum  plates  was  quantitatively  compared  using  advanced
