Abstract: Roof frames and methods of making the same are disclosed. Roof frames may comprise at least a first, second, third, and fourth structures. One or more of the structures may comprise a first surface formed from a first continuous fiber composite comprising a multidirectional laminate. At least one of the first, second, third, and fourth structures may comprise a second surface formed from a second continuous fiber composite comprising a unidirectional laminate, wherein the first surface and the second surface are selected to be formed from the first continuous fiber composite and the second continuous fiber composite, respectively, based at least upon a stress analysis for the respective surface, wherein the first surface exhibits a higher stress profile as compared to the second surface.
