An aerospace vehicle (100) includes a plurality of composite stiffeners (220). Each stiffener of the plurality has a stack of plies of reinforcing fibers. To increase stiffness without increased weight, at least some of the plies in the stack have reinforcing fibers oriented at ±± with respect to an axis of primary loading, where ± is between 2 and 12 degrees. At least some of the plies in the stack have reinforcing fibers oriented at ±² with respect to the axis of primary loading, where ² is between 50 and 85 degrees.
