Abstract
The SAE Brazil Aerodesign competition is aimed at engineering students who wish to enhance their knowledge in the field of aerodesign by undertaking the theoretical and practical design of a radio-controlled aircraft. Therefore, as in various other areas, it is crucial that materials are selected appropriately in Aerodesign, making the project as optimized as possible. The method developed by Michael F. Ashby was used in conjunction with simulations using the finite element method in the Ansys software to validate the application of composite materials made from natural fibers (such as jute and Curauá fibers) to construct the aircraft’s landing gear by the team. Evaluating aspects such as mechanical strength and the weight-to-strength ratio of the tested materials compared to the same parameters offered by higher-cost materials, such as carbon fiber or glass fiber, used by the team in previous projects. With the applied methodology, it was found that the selected materials were able to meet the mechanical demands imposed by the project, as well as provided cost savings in the final product, validating their applicability in the design.
