FTL137 rigid woven friction material
FTL137 is a closely woven, semi-flexible friction material. It is based on yarn spun from a blend of glass and synthetic fibres together with a fine copper wire to enhance its strength and heat dissipation properties. The impregnant has been specially developed to give it good frictional properties combined with a good degree of flexibility. It has a high coefficient of friction and performs well in wet and damp environments which makes it particularly suited for marine applications.
Published values are a starting point. Selection depends on the complete application.

FTL137 is a closely woven, semi-flexible friction material. It is based on yarn spun from a blend of glass and synthetic fibres together with a fine copper wire to enhance its strength and heat dissipation properties. The impregnant has been specially developed to give it good frictional properties combined with a good degree of flexibility. It has a high coefficient of friction and performs well in wet and damp environments which makes it particularly suited for marine applications.
To help during fitting to brake shoes and bands it can be softened and made more pliable by warming in a bonding oven to between 150 & 180 °C for sufficient time for the heat to penetrate the fabric.
This material is not suited to operate in oil-immersed conditions
Applications
- Industrial drum and band-brakes.
- Industrial clutches.
- Marine mooring & towing winches.
- Miscellaneous industrial devices.

Engineering capability backed by controlled manufacture and inspection
SDTS approached FTL after the original aircraft brake pad was no longer available. FTL redesigned the pad, established a replacement material route and manufactured a component aligned with the stated aeronautical technical requirements, supporting SDTS's modification-certification process.
“To continue flying our aircraft, we approached FTL to find replacement solutions for our brake pad problem, as the original part was no longer available on the market. The quality of our discussions, from both a technical and commercial standpoint, FTL's responsiveness in redesigning the pad with a material that meets aeronautical technical requirements, and their ability to adapt to our aeronautical environment allowed us to certify a modification applicable to our aircraft. The quality of the manufactured product is remarkable. Thanks to FTL, we can continue to fly, land, and brake safely.”

Bring us the application, drawing or performance problem.
Tell Friction Technology what the component or friction system needs to do. A short initial brief is enough to start. The right technical and commercial people then join the conversation to understand the operating conditions, available information and required next step.
Optional drawing or specification upload. No long technical questionnaire at this stage.
