Abstract: Forming systems and methods for forming an elongate charge of composite material are disclosed herein. The forming systems include an elongate forming tool having an elongate forming surface with a forming surface shape that corresponds to a predetermined material shape for the elongate charge of composite material. The forming systems also include an elongate end effector, which is configured to tension the elongate charge of composite material across the forming surface. The elongate end effector includes an elongate vacuum distribution manifold, a porous elongate vacuum region, and an elongate friction surface. The methods include methods of tensioning an elongate charge of composite material across an elongate forming surface of an elongate forming tool utilizing an elongate end effector.
