导弹发射箱用平板型复合材料多瓣薄膜盖的研制
Development of a Flat Multiple Composite Film Cover for Missile Launcher
摘 要
设计了一种平板型复合材料多瓣薄膜盖，其环向和径向设计了带V型凹槽的薄弱区，薄弱区主要由ER3600环氧树脂进行胶接，在树脂层上用玻璃纤维毡增强环氧树脂进行了加强处理，非薄弱区均采用玻璃纤维毡增强环氧树脂材料；采用有限元方法和冲破试验对薄膜盖性能进行了验证。结果表明：有限元方法预测得到薄膜盖的破坏压力在0.15 MPa左右，试验测得的破坏压力约为0.135 MPa，模拟和试验结果相近；且薄膜盖均沿薄弱区破裂成四瓣，环向齐根断裂，非薄弱区均保持完整，说明设计的薄膜盖满足技术指标要求。

Abstract
A flat multiple composite film cover was designed. The film cover had weak areas with V-shaped grooves along circumference and radial direction. The weak areas were bonded with ER3600 epoxy resin, and the resin layer was enhanced with the glass fiber mat reinforced epoxy resin on it. Non-weak areas were all made up of the glass fiber mat reinforced epoxy resin. The property of the film cover was verified by finite element method and bursting test. The results show that the failure pressure of the film cover predicted by the finite element method was about 0.15 MPa, and that by test was about 0.135 MPa. The simulation and test results are close. The film cover broke up into four parts along the weak areas, the circumferential root fracture occurred, and non-weak areas kept intact. It was indicated that the designed film cover meets the technical requirements.
