为探究碳纤维复合材料在便携式武器中的应用，开展了发射筒结构性能与复合材料铺层方法的技术研究。通过试验获取某型发射筒的工作压力，并应用有限元数值仿真方法建立不同的碳纤维复合材料铺层模型，进而对发射筒在工作载荷下的力学性能进行研究。研究结果表明，碳纤维铺层方式对发射筒的刚度及损伤失效有较大影响。发射筒在相同工作压力、相同铺层层数和总厚度的条件下，铺层方式Ⅰ的发射筒结构最大变形为2.41 mm，方式Ⅱ最大变形为7.66 mm，后者是前者的3倍多。根据Hashin失效准则，方式Ⅰ的碳纤维筒体未出现损伤，方式Ⅱ的筒体除中间第6 ~ 12层纤维层未出现损伤外，其余各层均萌生了较大范围的起始损伤点。研究结果可为发射筒的结构设计和碳纤维复合材料铺层方案提供参考。

In order to explore the application of carbon fiber composite in portable weapons, the technical research on the structural properties of the launcher and the method of composite laminating was carried out. The working pressure of a certain type of launcher was obtained through experiments, and different carbon fiber composite layering models were established by using finite element numerical simulation method. Then the mechanical properties of the launcher under working load were studied. The results show that the layering method of carbon fiber has a great influence on the stiffness and damage failure of the launcher. Under the condition of the same working pressure, the same number of layers and the total thickness, the maximum deformation of the launcher structure is 2.41 mm in the layering mode Ⅰ. The maximun deformation of mode Ⅱ is 7.66 mm, and the latter is more than 3 times of the former. According to the Hashin failure criterion, there is no damage in the carbon fiber cylinder of the mode Ⅰ, except for the 6th to 12th fiber layers in the middle of the cylinder according to the mode Ⅱ, a large range of initial damage points are found in other layers. The research results can provide reference for the stucture design of the launcher and the carbon fiber composite layering scheme.
