* Aluminium, titanium, and advanced composite materials are the primary materials used in the construction of fighter jets.
* Aluminium:
- The most common material used in the construction of fighter jets.
- Provides a good combination of strength, weight, and affordability.
- Used for the fuselage, wings, and other structural components.
* Titanium:
- Strong, lightweight, and resistant to high temperatures.
- Used for components that must withstand high stress, such as the engine mounts, landing gear, and wing spars.
* Advanced composite materials:
- such as carbon fiber, glass fiber, and Kevlar, offer high strength and low weight.
- Used for components such as the wing skins, tail surfaces, and radar domes.
Secondary Structures
* Plastics, rubbers, and metals are used to construct secondary structures, such as the canopy, fuel tanks, and seats.
* Transparent plastics, such as polycarbonate, are used for the canopy to provide clear visibility for the pilot.
* Synthetic rubbers are used to make fuel tanks and other components that must be resistant to fuel and hydraulic fluids.
* Metals such as aluminium and titanium are used to make seats and other structural components that must be strong and lightweight.
Coatings and Finishes
* Paints and coatings are used to protect the fighter jet from the elements and to reduce its radar signature.
* Special coatings are used to reduce friction and improve the jet's aerodynamic performance.
* Anti-radar coatings are used to reduce the jet's radar signature and make it more difficult to detect.
