PROBLEM TO BE SOLVED: To provide a method for enhancing productivity by reducing the number of components of a stringer used for improving stiffness in a vehicle such as an aircraft.SOLUTION: A stringer 100 includes a base flange 104, a web 102, and a noodle 114. The noodle includes a unidirectional fiber top portion 210 and a stacked laminate bottom portion coupled to the top portion. The bottom portion includes a predetermined number of stacks 220, each stack including three plies having three corresponding fiber orientations within an acreage region of the stringer. In a transition region 204 of the stringer, the stacked laminate bottom portion includes a predetermined number of stacks, each stack including the first and third plies of the acreage region.SELECTED DRAWING: Figure 2
