There is described a method comprising: (a) assembling a flat composite charge (100) to a thickness in a predetermined orientation; (b) forming a cut line (114) on the flat composite charge having opposing 45 degree beveled edges angled outward from the cut line; (c) positioning the flat composite charge centered about a tooling plunger (132) such that the tooling plunger is aligned with the cut line; and (d) activating the tooling plunger to move downward and fold the flat composite charge at the cut line into a cavity (134) of a forming mandrel (126, 128). At completion of movement of the tooling plunger and resulting folding of the flat composite charge, the opposing 45 degree beveled edges form a flat surface perpendicular to the cut line and form a first flange (136) and a second flange (138) connected to the flat surface.
