Abstract Scope |
The Markforged Mark Two 3D printer is capable of printing various orientations of continuous fiber reinforcement. An initial study of how the orientation of the fiber influences the strength characteristics (tensile and flexural properties) was conducted. Four combinations of carbon fiber reinforcement orientations were tested, specifically unidirectional, isotropic, concentric and a combination of isotropic and concentric, with onyx as the matrix material. The results will aid in designing a wing with the optimum fiber configuration, that will give the desired mechanical properties based on the forces acting on the wing. Design for Additive Manufacturing (DfAM) concepts and tools will be used to design and manufacture a large UAV wing. The design methodology will be a product-process co-design optimization method. A structural optimization technique will be used to determine the optimum layout of the carbon fiber material, and design for multiscale structures will be considered for the remaining interior regions. |
