Stronger, Lighter
Interior and exterior aerospace brackets withstand extreme temperatures, repetitive use, and more. Greene Tweed components are uniquely equipped to tackle the extreme conditions of aerospace applications:
- Aerospace-grade carbon fiber pre-preg tape (AS4/PEEK, PEKK, PEI)
- Application weight savings of 35-50%
- OEM and Tier 1 supplier approvals (incl. GE, Rolls Royce, Pratt & Whitney, Collins Aerospace, Safran)
- Excellent impact performance thermal stability, chemical and environmental resistance
High Performance, Low Friction
Simplify installation and extend the service life of critical components with Greene Tweed’s low-friction, ultra-durable rod and piston seals:
- Actuators, flight controls, and landing gear
- Improved gland stability
- Reduced friction, efficient lubrication leading to longer seal life
- Retrofits existing glands
- Reduced seal roll and spiral failure
Versatile Sealing and Scraping that Meets the Demands of Aerospace
When equipment failure is not an option, Greene Tweed MSE® metal spring energized seals provide superior sealing in even the most volatile conditions:
- High pressure or low pressure requirements, from vacuum up to 30,000 psi (2,070 bar) plus
- Large temperature variation, cryogenic to 550°F (288°C)
- Critical friction requirements
- Critical wear and life requirements
Proven Performance at 40,000 Feet
When it comes to critical aerospace applications, resistance to the elements is a must. Greene Tweed molded composite parts deliver enhanced mechanics and performance in even the harshest environmental conditions:
- Hail impact, erosion, bird-strike, and FST (fire, smoke, toxicity
- Typically 35-50% lighter than metallic parts
- Proprietary compression molding for increased part complexity and performance
- Resistance to extreme chemicals, temperature, and impact
