Flax Fibre Reinforcements

ATL Composites offers a modern range of Flax Fibre reinforcements designed for lightweight, high-performance composite laminates with a substantially reduced environmental footprint. Manufactured from renewable, bio-based flax fibres, these reinforcements deliver excellent stiffness, vibration damping and acoustic performance, making them ideal for marine, architectural, lifestyle and sporting applications where sustainability and aesthetics matter.

Flax composites combine natural fibre appeal with impressive mechanical performance, providing a warm, organic appearance and smooth drape characteristics that suit both visible and structural laminates.

Key Benefits

Renewable, sustainable reinforcement with low embodied energy
High specific stiffness, especially in sandwich and panel applications
Superior vibration & acoustic damping for comfort and noise control
Attractive natural aesthetic suitable for visible laminates
Reduced environmental impact through bio-based fibre content
Good drapability and handling, especially over curved surfaces
Compatible with hybrid lay-ups (carbon/flax or glass/flax)

* A variety of weight and orientations are available on request.

Perfect Match for KINETIX® R135 Bio-Based Surfboard Epoxy

Flax fibre reinforcements pair exceptionally well with KINETIX® R135 – the ultra-clear, UV-stable, bio-based surfboard laminating & filler epoxy system.
Together they create a premium, environmentally conscious composite system for surf, lifestyle and performance laminates.

Why Flax + R135 is an ideal combination

Natural Aesthetic + Ultra-Clear Resin
Flax’s warm, organic texture shows beautifully under R135’s crystal-clear, bloom-free finish.
Environmentally Driven Pairing
R135 contains 26% bio-based carbon (verified to ASTM D6866-16), complementing flax’s renewable fibre origin.
UV-Stable Clarity
R135 maintains its appearance in sunlight, preventing yellowing and allowing flax’s natural colour to remain vibrant.
Superior Fibre Wet-Out
R135’s fast wet-out makes flax laminations clean, consistent and visually premium.
High Strength & Durability
Flax offers excellent toughness and vibration damping, while R135 provides epoxy-grade mechanical performance.
Sustainable Performance for Modern Surfcraft
The combination is ideal for surfboards, paddleboards, watercraft components, and lifestyle products where sustainability and aesthetics matter.

R135 is compatible with:

Flax
E-glass
Carbon
Hybrid fibre systems
Timber, EPS and PU foam blanks

Together, Flax and R135 deliver eco-driven, performance-proven composite solutions for surfboard builders and modern composite designers.

Typical Applications

Surfboards, paddleboards & lifestyle watercraft
Interior joinery, furniture & panel systems
Visible laminates with natural fibre aesthetics
Architectural acoustic panels
Sporting goods and eco-conscious consumer products
Hybrid laminates for balanced stiffness and damping

Designed for ATL’s Composite Ecosystem

Flax reinforcements integrate seamlessly with:

KINETIX® laminating epoxies (R135, R246TX, R118, R260 etc.)
Techniglue® structural adhesives
DuFLEX® and Featherlight® panel systems
Polyester, vinyl ester and PU resins

Ensuring reliable curing, excellent fibre wet-out and consistent long-term performance across sustainable, structural and decorative composite applications.

frequently asked questions

How does ATL tailor composite systems for different industries?

Every industry has distinct performance, compliance, and manufacturing requirements. ATL’s in-house chemists and engineers develop and refine epoxy systems, adhesives, and core materials to meet the specific demands of marine, defence, aerospace, automotive, industrial, civil, architectural, and sporting applications — ensuring every product delivers optimal strength, efficiency, and durability.

Can ATL customise materials for my project or process?

Yes. ATL offers custom formulation and process engineering support to align material performance with your production requirements — whether infusion, hand lay-up, lamination, bonding, or CNC-routed panel construction. Our technical team collaborates closely with customers to deliver precision-matched resin systems and structural solutions for unique applications.

Are ATL’s composite systems certified for high-performance applications?

Absolutely. ATL operates under an ISO 9001:2015-certified quality management system, with selected materials approved by DNV for use in structural and high-load applications. Every ATL system is manufactured to exacting standards of performance, consistency, and traceability to meet the demands of defence, industrial, and advanced engineering environments.

What makes ATL’s materials suitable for large-scale or structural builds?

ATL’s epoxy systems, structural panels, and composite cores are engineered for high strength-to-weight performance, dimensional stability, and fatigue resistance. These attributes make ATL materials ideal for large composite assemblies, modular structures, and precision-engineered components where long-term strength, weight reduction, and reliability are essential.

Does ATL offer sustainable or bio-based composite options?

Yes. ATL is committed to advancing sustainable composite technology, offering USDA-Certified Bio-Based epoxy systems and environmentally conscious materials that reduce waste, extend service life, and minimise environmental impact. Our ongoing R&D focuses on improving sustainability without compromising structural integrity or mechanical performance.

How can I select the right ATL system for my application?

Choosing the ideal composite system depends on your structure’s design, load requirements, manufacturing process, and environmental exposure. ATL’s in-house engineers and chemists provide tailored advice to ensure the correct combination of resin, core, adhesive, and surface technology for your project.
To discuss your application or request technical guidance, contact ATL’s Technical Team — we’ll help you identify the most effective and efficient composite solution for your build.
