摘　　要：选用的“离位”增韧原理通过模压的方式制备碳纤维织物(CF)和芳纶蜂窝(AF)夹芯军用方舱架构;依次以CF型号、CF克重、CF方向为影响因素,采用单因素分析进行工艺优化,并对其增韧效果和耐撞击性能进行测试。试验表明:CF-AF蜂窝夹芯架构增韧效果明显,且在CF(T700,600 g/m^(2)±45°)、上下蒙皮均为2层时耐撞击性能最优,符合GJB2093A-2012军用方舱通用试验方法。The selected“off-position”toughening principle was used to prepare the military shelter structure of car-bon fiber fabric(CF)and aramid honeycomb(AF).With the model,the weight and the direction of CF as the influencing factors,the process was optimized by single factor analysis,and its impact resistance and toughening effect were tested.The results show that the toughening effect of CF-AF honeycomb sandwich is obvious,and the impact resistance is the best when CF(T700,600 g/m^(2)±45°)and the upper and lower skins are both 2 layers,which conforms to GJB2093A-2012.
