High-Performance Plastics and Machined Metal Components in Commercial Airlines
The aerospace industry demands materials and components that can withstand extreme conditions while delivering reliability, efficiency, and safety. Commercial aircraft operate under high stress, from fluctuating pressures and temperatures to continuous mechanical loads, and every component plays a role in ensuring safe and efficient flight.
At Fluorocarbon, we bring together decades of experience in both high-performance plastics and precision machined metal parts, supporting aircraft manufacturers and Tier 1 suppliers with materials and solutions designed for long service life in critical aerospace applications.
Why Use High-Performance Plastics in Commercial Aircraft?
Weight reduction is a constant priority in aerospace. Replacing metal components with lightweight, durable polymers allows airlines to save fuel, reduce emissions, and improve efficiency without sacrificing performance. High-performance plastics offer:
- Excellent strength-to-weight ratio
- Outstanding chemical and wear resistance
- Dimensional stability under thermal stress
- Reduced maintenance requirements
Examples of Plastics in Commercial Aircraft
- PTFE/Teflon (Polytetrafluoroethylene): Used in seals, gaskets, and wire insulation thanks to its low friction and high chemical resistance.
- PCTFE (Polychlorotrifluoroethylene): Excellent for oxygen service components due to its gas barrier properties and stability at low temperatures.
- PEEK (Polyether ether ketone): Common in brackets, clamps, and cable insulation; valued for its high mechanical strength and flame resistance.
- PI (Polyimide): Used in bushings and bearings where high-temperature stability and low wear are critical.
Typical Plastic Components
- Seals and gaskets for hydraulic and fuel systems
- Bearings and bushings in landing gear and control surfaces
- Insulation and cable guides in electrical systems
- Interior fittings where weight reduction enhances efficiency
The Role of Precision Machined Metals in Aviation
While advanced polymers replace metals in many non-structural areas, metal components remain essential in commercial aircraft for applications requiring exceptional load-bearing capacity, conductivity, or extreme durability.
At Fluorocarbon, our machined metal parts are manufactured to tight tolerances, ensuring safety-critical reliability in aerospace systems.
Common Aerospace Metals We Machine
- Aluminium alloys: Lightweight and corrosion-resistant, widely used in structural parts.
- Titanium alloys: Exceptional strength-to-weight ratio and resistance to fatigue and heat.
- Stainless steels: Used where strength, toughness, and wear resistance are needed.
Typical Metal Components
- Actuator housings for flight control systems
- Hydraulic fittings and manifolds
- Engine and turbine components
- Landing gear parts and precision fasteners
Complementary Expertise: Plastics and Metals Working Together
The strength of modern aerospace engineering lies in combining the right material for the right application. For example:
- Hybrid assemblies may include PEEK bearings within titanium housings, balancing low-friction movement with high structural strength.
- PTFE-based seals are used alongside precision-machined metal fittings to ensure leak-free performance in hydraulic and fuel systems.
- Cabin interior brackets use lightweight plastics, while load-bearing elements remain metallic, optimising performance and safety.
By offering both polymer solutions and metal machining expertise, Fluorocarbon supports customers in developing components that meet stringent aerospace standards while maximising efficiency and longevity.
