目的 以某型发射箱复合材料箱体为对象， 探讨复合材料箱体的纤维增强材料铺层设计方法。方法 以箱体质量为控制为目标， 运用复合材料层合板力学理论结合有限元分析方法进行纤维增强材料铺层计算。结果 将纤维的体积分数控制在43.6%， 箱体玻璃纤维布铺层总数量为10层， 可实现箱体的质量控制目标为 （23±1） kg。结论 获得的纤维增强材料铺层方式可有效保证箱体的质量一致性和尺寸控制要求。

The aim of this work was to explore the method of overlay design of fiber-reinforced material for a type of launch box. With the goal of controlling the weight of the box, the composite laminates mechanical theory combining with the method of finite element analysis were used to calculate the overlay design of fiber-reinforced material. When the fiber volume content was controlled in 43.6% and the total number of glass fiber cloth laminate layers was 10, the goal of box weight control in range of (23 ± 1) kg was achieved. The method of overlay design of fiber-reinforced material could effectively ensure the weight consistency and size control requirements.
