Reducing costs and emissions through material expertise

Challenged to deliver a safe and sustainable aircraft material that was both simple and high-performing, our industry experts helped improve an aircraft wing flap system.


Duratron® PAI case study summary

We worked alongside a major Aerospace manufacturer to help reduce friction and wear within their aircraft wings. A simplified, self-lubricating plastic solution replaced the need for complex, labor-intensive parts. This resulted in a lighter plane, with a lower risk of failure, reduced maintenance requirements, and a more sustainable carbon footprint.

Our unique self-lubricating PAI solution has been adopted by other manufacturers, further improving sustainability across the entire Aerospace industry.

Industry: Aerospace, Commercial Aviation

Solution: Development of integral, self-lubricating wear strips for wing flaps

Product: Duratron® T4301 PAI

Results: A lighter plane with a lower risk of failure and reduced maintenance requirements


Maintaining structural integrity while increasing material flexibility

While developing a new aircraft with the goal of reducing fuel consumption and CO₂ emissions, a major Aerospace manufacturer selected flexible and lightweight composite materials with an aluminum structure for the wings.

However, ensuring continual wing flexibility, structural integrity and passenger safety meant these parts would require regular monitoring, lubrication, and maintenance.

The proposed solution required a highly complex control mechanism to ensure all roller bearings continued to function properly, even across the wide range of temperatures associated with changing altitudes, and extended exposure to various chemicals used around wing structures.


Removing friction and complexity

Instead of simply finding suitable engineering materials for a complex roller-based mechanism, we explored the possibilities and developed an alternative integral solution.

We recommended integrating a single self-lubricating plastic wear strip between between mating surfaces in the wing flaps, which would not only prevent friction, but also simplify the part and reduce maintenance requirements.

Working in conjunction with fabrication partners and the manufacturer’s engineers, we ran extensive tests to ensure the self-lubricating plastic material (Duratron® T4301 PAI) met every client and industry requirement and was authorized for use in aircraft.

Partners in possibility

A key part of this project’s success was our commitment to look beyond the brief and see what’s truly possible. While initially tasked with finding a suitable material to deliver to our customer's engineering requirements, we utilized our specialist knowledge and vast network of experts to propose an alternative integral solution that enhanced the entire industry.


Integrated solutions for safe and sustainable aircraft 

Thanks to its simplified design, the single self-lubricating plastic wear strip not only delivered to our customer’s needs but also resulted in a lighter plane with a lower risk of failure and reduced maintenance requirements. Additionally, it delivered better fuel efficiency and reduced CO₂ emissions, creating a more sustainable aircraft.

  • Lighter aircraft
  • Lower risk of failure
  • Lower cost of maintenance
  • Better fuel efficiency
  • Reduced CO2 emissions
  • More sustainable aircraft
