Abstract
This research explores the potential of using carbon plastic composite materials to optimize the structure of unmanned aerial vehicles (UAVs). The main issue addressed is reducing the weight of drones while increasing their strength and aerodynamic stability. The study found that the specific strength of carbon composites is 1500 MPa/g/cm³, which is three times higher than that of conventional materials. Additionally, the structural vibration resistance increased by 25-30%, and the weight was reduced by 25%. These results are explained by the low density of the material (1.55 - 1.65 g/cm³) and optimal distribution of stresses in the structure. A key feature of the research is the use of a method based on actual CAD modeling and numerical simulations, and the assessment of the efficiency of 3D printing and Out-of-Autoclave technologies, which supports its industrial potential. The findings can be applied in the construction of lightweight, reliable, and energy-efficient drones. Practical applications of these materials include military, agricultural, and emergency rescue systems, with usage conditions in environments with moderate temperatures and vibrational loads.
