The increased demand in production quantities in the aviation, transportation, and defense
industries has led to the significant prominence of composite materials in the sector due to their
technical capabilities. The effects of changes in production methods of preferred composite
materials due to their mechanical properties will be examined in the manufacturing of aircraft
components. In this context, optimal technical capabilities and cost analyses will be investigated
for the production routes to be used during the project initiation, prototype, and transition to
mass production phases in aviation. The study includes thermoset matrix carbon fibers and glass
fibers used in the manufacturing of unmanned aerial vehicle wing shells, incorporating
autoclaves and oven devices. In the production process, 18 samples were produced using the
lay-up method of dry and prepreg fabrics, and their mechanical tests were conducted under
pressurized and normal atmospheric conditions. It is anticipated that the mechanical properties
of the samples produced with carbon fiber prepreg fabric and cured under pressure will yield
results at least 20% higher compared to other sample types. In the cost analysis, it was
calculated that the sample produced with the same experimental type is 28% cheaper than the
sample produced with dry carbon fiber fabric using the wet lay-up method. Considering the
technical requirements of product in the transition from prototype manufacturing to mass
production of composite materials used in UAV systems, it was determined that in the prototype
process, Sample 6 (GFW8 WUD) achieves the optimal benefit/cost ratio, while in the mass
production process, taking into account payload, flight time, and loads during flight, Sample 1
(CAP8 WUD) will be used despite the increase in costs.
