The combination of polymeric materials used in 3D printing and carbon fibers gives designers new possibilities in the design of light load-bearing structures. Such a reinforced material can be found in thin-walled structures. A good example is the wheel of a Mars rover, the structure of which is expected to be low in weight, with adequate strength and durability as well as deformations within the assumed range - ensuring vibration damping in the rigid suspension of a special vehicle. The paper presents the process of designing such a wheel within the limits of the Europen Rover Challenge competition regulations and the technological possibilities of a low-budget project. The conducted experiment confirmed the correctness of the assumptions and indicated potential directions for further work.
