At the German Aerospace Center in Augsburg, a solid rocket motor case in full-scale dimensions (Diameter: 3.5m, Length 6m) is built of dry carbon fiber semi-finished products. An automatically preforming approach is chosen to build on one hand the pressure vessel by the Dry-Fiber-Winding process and on the other hand two skirts by the Dry-Fiber-Placement process. This article describes the preforming processes of both carbon-fiber-reinforced-plastic components of the motor case. The goal is the verification of the process for industrialisation.
