An Airbus A350 wing panel is designed to withstand decades of pressure cycles, temperature changes and aerodynamic forces. Its carbon-fibre composite structure is light, stiff and durable. But the same qualities that make it valuable in flight become obstacles when the aircraft reaches the end of its working life.

Unlike aluminium or titanium, a conventional carbon-fibre composite cannot simply be melted and recast. Its reinforcing fibres are locked inside a cured polymer matrix specifically designed not to come apart.

Fairmat, a French deep-tech company founded in 2020, is developing an alternative to burning away that resin or grinding the material into lower-value fibres. It cuts composite waste into reusable chips, characterises them digitally and robotically assembles them into new laminates.

A research contract disclosed by Fairmat in March 2026 will see the company and Airbus investigate the disassembly and recovery of composite panels from aeronautical structures, including wing and keel-beam elements used in long-haul aircraft such as the A350. Composites account for approximately 53% of the A350’s structure by weight.

No Fairmat material has been announced as qualified for a certified flying component. The project will instead examine whether material recovered from aircraft structures can meet the performance, consistency and traceability requirements of demanding industrial applications—including, potentially, aerospace itself.

That is a considerably harder problem than keeping factory waste out of landfill.

 

Preserving the composite rather than extracting the fibre

 

Most carbon-fibre composites contain reinforcing fibres embedded in thermoset resin. Once cured, the resin cannot be reheated and reshaped like a thermoplastic.

Established recycling routes therefore tend to attack either the resin or the structure. Pyrolysis typically uses temperatures between 400°C and 700°C to decompose the polymer and recover the fibres. Solvolysis uses solvents or reactive fluids to break down the resin. Mechanical recycling usually cuts or grinds the composite, often producing shorter fibres or powders for less demanding applications.

Each method involves trade-offs in energy use, chemical consumption, fibre quality and cost. A technical review by the UK’s National Physical Laboratory notes that thermal processing is the most widely researched and commercially used route, but also identifies continuing difficulties around the quality, consistency and reuse of recovered fibres.

Fairmat’s established process takes a different approach. It produces cured, single-ply composite elements known as Fairmat Chips from suitable carbon-fibre reinforced polymer waste. Depending on the incoming material, these preserve the original fibre length and orientation together with the existing resin system, rather than reducing the waste to loose short fibres.

The chips can then be assembled into FairPly, a sheet or roll designed to fit into composite-manufacturing processes. Fairmat describes this first-generation chip-making method as mechanical. Its newer closed-loop system adds a separate cold-plasma stage.

The distinction is important: Fairmat is not initially trying to return every piece of waste to bare fibre. It is preserving larger parts of an engineered structure and rearranging them into another one.

 

Making variable waste behave consistently

 

That approach protects more of the material’s value, but creates a manufacturing problem. Waste is inherently variable.

Composite offcuts may differ in fibre direction, thickness, resin chemistry and physical condition. Material removed from an old aircraft adds further uncertainties involving coatings, contamination, repairs, environmental exposure and service history.

Fairmat says its factories use physical measurements and computer vision to inspect the geometry, edges and properties of incoming pieces. Machine-learning models classify the chips before robots arrange them in overlapping layers. A proprietary data system records information throughout production and supports adjustments to the manufacturing process.

Artificial intelligence has a specific role here: managing variation. The objective is to group and position heterogeneous pieces so the finished laminate delivers repeatable properties.

That capability will be central to the Airbus project. Aerospace qualification requires much more than a strong laboratory sample. Manufacturers need evidence covering batch variation, fatigue, damage tolerance, environmental exposure and long-term durability. They must also be able to trace the material’s origins and processing history.

A recycled composite can perform well in a tennis racquet or orthotic device and still be far from approval for an aircraft structure.

 

Hexcel and Syensqo supply the starting material

 

Fairmat’s relationships with Hexcel and Syensqo help it address the feedstock problem. Production offcuts from major composite manufacturers are generally cleaner and better documented than components recovered after decades in service.

Hexcel, which produces carbon fibre, reinforcements and prepregs, began working with Fairmat in Europe in 2021. In 2024, the companies signed a ten-year agreement covering composite waste from Hexcel’s Salt Lake City operation. Hexcel has said that almost all prepreg offcuts from its European production are being diverted from landfill and processed for commercial reuse.

Syensqo signed a similar agreement in June 2025, initially covering prepreg waste from its UK operations. The partnership was extended in 2026 to include its composites facility in Östringen, Germany.

“We see in Fairmat a mature partner that offers a reliable and sustainable business model,” said Gabriel Molina, sustainable development director at Syensqo Composite Materials.

These agreements give Fairmat relatively well-characterised inputs in predictable volumes. The Airbus project presents the next test: whether its automated system can accommodate more complicated material recovered from end-of-life structures.

 

Designing a composite to come apart

 

Fairmat’s more ambitious circularity claim rests on Infinity Recycling, its patented cold atmospheric-plasma process.

Fairmat laminates are built from overlapping composite chips separated by narrow gaps containing newly added resin. At the end of the product’s next life, plasma is used to remove this connecting resin. A six-axis robotic arm can then extract the preserved chips for another lay-up.

The process does not strip all resin from any conventional carbon-fibre component. It is designed to recover building blocks from material previously manufactured according to Fairmat’s own architecture.

In effect, the company is incorporating predetermined disassembly points into the composite.

Fairmat says the approach can recover up to 90% of the material, permit repeated recycling and emit up to ten times less carbon dioxide than its first-generation chips. It does not use liquid solvents or high-temperature combustion. Those figures remain company claims: Fairmat has not publicly released sufficiently detailed data to establish how many complete cycles have been demonstrated, how performance changes after each cycle or how much energy the plasma stage consumes per kilogram.

The company says its environmental calculations are based on lifecycle assessments reviewed by independent specialists. However, a public assessment detailing the methodology, system boundaries and reviewers could not be identified. The emissions claims should therefore not be treated as independently reproducible evidence until that documentation is available.

 

Institutional scrutiny, but not aerospace validation

 

Fairmat has nevertheless passed several forms of external scrutiny. In 2025, the European Investment Bank provided a €25 million venture-debt loan to support its industrial expansion. The EIB’s project assessment described Fairmat’s technology as an “innovative, efficient and sustainable” system and said the investment would support development of materials, automation, robotics and production capacity between 2025 and 2028.

The financing indicates that the bank conducted technical, financial and environmental due diligence before committing capital. It does not amount to independent validation of every performance claim or prove that the material meets aerospace certification requirements.

Fairmat has also been a certified B Corporation since 2024, with a published B Impact score of 106. B Corp certification independently assesses a company’s wider governance, workforce, community and environmental practices. It is supporting evidence of corporate impact standards, not a technical certification of Infinity Recycling.

 

Factory waste is the easier test

 

Fairmat already supplies materials for sports equipment, construction, mobility, electronics and orthotic care. The Airbus contract moves it towards a more difficult category of waste.

Fresh manufacturing offcuts come from a controlled environment. An aircraft panel may be decades old, joined to other materials and affected by repairs, coatings and accumulated damage. Recovering it is only the first step; proving what it can safely become is the harder one.

Neither Airbus nor Fairmat has disclosed the project’s expected volumes, performance thresholds or qualification pathway.

“By combining Fairmat’s technology with the standards of a leading aircraft manufacturer, we aim to transform end-of-life aircraft structures into high-performance materials for reintegration into aerospace applications,” said Fairmat founder and chief executive Benjamin Saada.

For now, “aim” remains the operative word.

Fairmat’s deeper proposition is not merely that carbon-fibre waste can be made useful. It is that waste can be measured, classified and rebuilt precisely enough to become a material that engineers can specify.

If that model succeeds, the company’s robots will not simply recycle carbon fibre. They will turn yesterday’s engineered structures into controlled raw material—and design that material so it can be taken apart again.
