Abstract: Embodiments refer generally to systems and methods for manufacturing a cylindrical spar tube of the sort that might be used in a horizontal stabilizer for a helicopter. An exemplary method may comprise laying out onto a flat surface (and possibly stacking) plies of composite material, rolling the material onto a mandrel while applying pressure and curing the rolled material.
