A method for forming a curved composite charge, the method comprising: positioning a planar composite charge on a processing surface of a pallet and over a cavity of the pallet, wherein: the planar composite charge comprises a hat portion and flange portions, monolithic with and interconnected by the hat portion, and the pallet comprises a plurality of pallet portions, wherein each pallet portion of the plurality of pallet portions is rotatably coupled to at least one other pallet portion of the plurality of pallet portions, the cavity extends through each pallet portion of the plurality of pallet portions, and the planar composite charge is positioned over and contacts, each pallet portion of the plurality of pallet portions; contacting the hat portion of the planar composite charge with a die such that the die is aligned with the cavity, the cavity is defined by a cavity surface; either (i) folding at least the hat portion to conform to the die and inserting the die into the cavity such that the hat portion is positioned between the die and the cavity surface or (ii) inserting the die into the cavity such that the hat portion is positioned between the die and the cavity surface and is folded to conform to each of the die and the cavity surface; and rotating two or more pallet portions of the plurality of pallet portions relative to each other around one or more axes, thereby forming a curved composite charge; wherein the one or more axes comprises a first axis and a second axis, the first axis is perpendicular to the processing surface of the pallet, the second axis is parallel to the processing surface of the pallet; whereby the method further comprises rotating the two or more pallet portions of the plurality of pallet portions relative to each other around the first axis and the second axis. positioning a planar composite charge on a processing surface of a pallet and over a cavity of the pallet, wherein: the planar composite charge comprises a hat portion and flange portions, monolithic with and interconnected by the hat portion, and the pallet comprises a plurality of pallet portions, wherein each pallet portion of the plurality of pallet portions is rotatably coupled to at least one other pallet portion of the plurality of pallet portions, the cavity extends through each pallet portion of the plurality of pallet portions, and the planar composite charge is positioned over and contacts, each pallet portion of the plurality of pallet portions; the planar composite charge comprises a hat portion and flange portions, monolithic with and interconnected by the hat portion, and the pallet comprises a plurality of pallet portions, wherein each pallet portion of the plurality of pallet portions is rotatably coupled to at least one other pallet portion of the plurality of pallet portions, the cavity extends through each pallet portion of the plurality of pallet portions, and the planar composite charge is positioned over and contacts, each pallet portion of the plurality of pallet portions; contacting the hat portion of the planar composite charge with a die such that the die is aligned with the cavity, the cavity is defined by a cavity surface; either (i) folding at least the hat portion to conform to the die and inserting the die into the cavity such that the hat portion is positioned between the die and the cavity surface or (ii) inserting the die into the cavity such that the hat portion is positioned between the die and the cavity surface and is folded to conform to each of the die and the cavity surface; and rotating two or more pallet portions of the plurality of pallet portions relative to each other around one or more axes, thereby forming a curved composite charge; wherein the one or more axes comprises a first axis and a second axis, the first axis is perpendicular to the processing surface of the pallet, the second axis is parallel to the processing surface of the pallet; whereby the method further comprises rotating the two or more pallet portions of the plurality of pallet portions relative to each other around the first axis and the second axis.
