Abstract

A method comprises wrapping a mandrel (300) with a composite tape (310) to form a composite tube (315). This wrapping operation allows forming composite tubular structures with any cross-sectional profiles defined by the mandrel. The wrapping is also used to control the fiber orientations in the composite tubular structures. The composite tube is then cut into composite tubular structures (110). In some examples, the composite tube is partially cured prior to the cutting, which allows removal of the mandrel while preserving the shape of the composite tube. This cutting operation allows forming composite tubular structures with different lengths, shapes, and orientations of the ends. The composite tubular structures are disposed on a support structure (320) and are bonded to each other. In some examples, this bonding operation also involves final curing of the composite tubular structures.
