Der A350 ist zum größten Teil aus Carbonfaser gebaut, etwa 70 Prozent. Metall kommt aber auch zum Einsatz:
The Airbus A350, while predominantly constructed from advanced composite materials, does incorporate metal components in several key areas. These metal parts are used where their specific properties, like strength, flexibility, or heat resistance, are advantageous. Here are some of the primary metal components in the A350:
1. Aluminum and Aluminum Alloys:
- Parts of the Wing Structure: Aluminum is used in certain areas of the wing where flexibility and fatigue resistance are important.
- Flight Control Surfaces: Elements like ailerons and flaps often use aluminum due to its balance of strength and lightness.
- Some Areas of the Fuselage: Aluminum alloys may be used in certain sections of the fuselage, particularly in areas that require more structural flexibility.
2. Titanium and Titanium Alloys:
- Engine Pylons: Titanium is used for its high strength and heat resistance, making it suitable for engine mounts.
- Landing Gear Components: Due to its strength and corrosion resistance, titanium is often used in landing gear components.
- Critical Fasteners and Fittings: Certain high-stress or high-heat areas may use titanium fasteners and fittings.
3. Steel and Steel Alloys:
- Landing Gear: The main structure of the landing gear is often made of steel for its high strength and ability to withstand the stress of takeoffs and landings.
- Hydraulic Systems: Steel is used in various components of the hydraulic systems due to its durability and resistance to high pressures.
- Certain Engine Components: Some parts within the engine that require high strength and temperature resistance may be made of steel alloys.
4. Other Metals and Alloys:
- Electrical Systems: Various metals, including copper, are used in the aircraft's electrical systems.
- Interior Fittings: Metals are sometimes used in cabin fittings and other interior components.
It's important to note that the use of these metals is carefully balanced with the advanced composite materials to optimize the aircraft's overall performance, weight, fuel efficiency, and maintenance requirements. The exact distribution and types of materials can vary depending on the specific model and configuration of the A350.
