Aramid fiber , F-12 Aramid fibre-made structural part of unmanned aerial vehicle (UAV)
Featuring light weight and good impact resistance, structural part made of F-12 aramid fibre is applied in the drone field.
These advantages of aramid fiber over metals are important in UAVs:
- low weight;
- excellent corrosion resistance;
- high resistance to fatigue;
- reduced machining;
- the ability to fabricate tapered sections and intricate contoured parts;
- the ability to orient reinforcement fibres in the direction of maximum stiffness and strength;
- the reduced number of assemblies and fasteners needed when using co-cure or co-consolidation composite manufacturing processes;
- a very low thermal expansion reducing operational problems in high altitude flight.
However, composites also have disadvantages compared to metals:
- higher cost;
- relative lack of established design criteria;
