Embodiments refer generally to systems and methods for manufacturing a cylindrical spar tube (120) of the sort that might be used in a horizontal stabilizer (108) for a helicopter (100). An exemplary method may comprise laying out onto a flat surface (220, 420) (and possibly stacking) plies (201, 202, 203, 301, 302, 303, P001-P004) of composite material, rolling the material (424, 624, 852) onto a mandrel while applying pressure and curing the rolled material. |
