A method for fabricating a hat stiffener which includes a step of positioning two or more reinforcement fiber layers about a mandrel. The method further includes a step of cutting through the two or more reinforcement fiber layers forming a first stack of first end portions of the two or more reinforcement fiber layers and a second stack of second end portions of the two or more reinforcement fiber layers wherein the first and second stacks are in overlying relationship with respect to the mandrel. In addition, the method further includes moving the first stack of the first end portions and the second stack of the second end portions of the two or more reinforcement fiber layers out of overlying relationship with respect to the mandrel.
