Frequently asked questions

Flax offers exceptional vibration damping : its loss coefficient (1.47%) is approximately 10 times greater than that of carbon (0.18%) or glass (0.15%). For the user, this means absorption of unwanted vibrations while maintaining control and feel of the equipment. Furthermore, its ductile and gradual breakage increases user safety compared to the brittle and sharp breakage of carbon.

With a density of 1.45 g/cm³ , flax is significantly lighter than E-fiberglass (2.55 g/cm³). Its specific modulus (stiffness relative to weight) is 30% higher than that of glass, allowing for the design of lighter structures with the same stiffness. In sports engineering, this advantage reduces equipment inertia (swing weight), improving maneuverability and performance.

It is primarily used to reinforce strategic areas: 

• Winter sports: Integration into ski stiffeners and snowboard decks to stabilize contact on hard snow.
• Racket sports: Use in frames and handles to filter frequencies harmful to the arm.
• Boating: Construction of surfboards, kitesurfing boards for a smoother "ride" in choppy water.

It is primarily an advanced engineering solution for resolving complex vibration dynamics problems. Its environmental aspect is an additional benefit: its production requires five times less energy than glass and it has a negative carbon footprint (CO₂ sink). Finally, it improves manufacturing comfort because it is non-irritating to operators.

While flax is naturally hydrophilic, proper resin selection and UV protection ensure excellent weather and UV resistance.

Absolutely. UD, woven, and mat formats provide reproducible performance for both small specialized runs and medium industrial volumes.

Using thermoplastic resins, components can be shredded and reintegrated via our Recytal process, supporting a true circular economy. Using thermoset resins, flax is naturally flammable which improves the energy recovery by thermal treatment.
