Filament Winding for Prototyping Composite Structures
Filament winding is an alternative process for creating the axisymmetric composites used in a variety of applications. Most appreciated for its ability to produce high-pressure gas storage tanks, it can also be used for structural rocket body tubes. A donated Composites Machine Company filament winding machine was overhauled for the purpose of creating prototype composite pressure vessels and airframes for high-power rocket applications. The winding mandrel is 6.35cm diameter and 2.7m long. The winding angle of the filament relative to the mandrel has a range of 0° to 90°, where 0° is along the axis of rotation and 90° is perpendicular to the axis of rotation. The machine is set for wet layup with a variable winding pattern that can repeat multiple times when traversing in one direction. The winding path model and code generation was accomplished with CADWIND V9. A composite overwrapped pressure vessel to hold 5.00 MPa and several 6.35 cm body tubes were successfully created for a hybrid rocket body and oxidizer storage tank.
