Keywords: conceptual design, optimization, high aspect ratio, uav wing, composite material

The applicability of an optimization routine included in the Ansys® software applied to fiber reinforced structures was analyzed via a practical example. A laminated wing was modeled and optimization parameters were defined such as weight, fiber orientation angle and failure criteria. Two optimization methods were used. Results are analyzed and the method restrictions are discussed and other methods are proposed.
