Method for fabricating a hat stiffener

A method for fabricating a hat stiffener 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. 一种用于制造帽形加固件的方法，包括将两个以上增强纤维层定位在心轴周围的步骤。该方法进一步包括切开两个以上增强纤维层的步骤，形成两个以上增强纤维层的第一端部的第一堆叠和两个以上增强纤维层的第二端部的第二堆叠，其中，第一堆叠和第二堆叠处于相对于心轴的重叠关系。另外，该方法进一步包括，使两个以上增强纤维层的第一端部的第一堆叠和第二端部的第二堆叠从相对于心轴的重叠关系移出。
