配橡胶内衬的复合材料板壳可以模拟真实纤维缠绕压力容器。本文通过比较复合材料被撞击的时间历程和频域曲线,检测了复合材料缠绕层与内衬之间、内衬与内衬之间的损伤区,并对某型火箭发动机壳体的缩小比例试件进行了实际检测。
Rubber-lined composite sheet shells simulate true fiber wound pressure vessels. In this paper, by comparing the impact time history of composite material and the frequency-domain curve, the damage zone between the inner layer and the lining and between the lining and the inner lining of the composite material was tested. The pieces were actually tested.
