A system and method for forming an integral flange in an end portion of a composite laminate structure, such as an aerospace or other vehicle structure. First and second tool components cooperate to support the structure during a layup process, with the second tool component imparting an initial angle to the end portion. A third tool component includes a male radius positioned at an apex of the initial angle. A heater heats a succession of localized areas along the end portion to lower a viscosity of the resin. A roller applies pressure to the succession of localized areas after each is heated so as to push them around and against the third tool component to form a flange angle and the integral flange. The heater and the roller may make multiple passes along the end portion, with the roller angle increasing with each pass until the flange angle is achieved.
