... Abstract The necessity of developing the lightest-weight structures with sufficient strength was the driving factor for the development of filament-wound composite pressure vessels. This chapter presents a brief history of the development of rocket motor cases (RMCs), followed by a comparison...

... is that of fiber bridging, where winding onto a concave shape is attempted and, as a result, the fibers do not remain in contact with the surface. Axisymmetric shapes have the advantage that, in the circumferential direction, there is always positive curvature; this can be seen in the rocket casing shown in Fig...
