E-Fibreglass Reinforcements

ATL Composites supplies a comprehensive range of DNV-certified E-Fibreglass reinforcements engineered for high-quality composite laminates across marine, transportation, automotive and industrial applications. As the global standard reinforcement, E-glass delivers an ideal balance of strength, drapability, and cost-efficiency—making it the backbone of both conventional and advanced composite construction.

ATL’s engineered E-Glass range includes double bias, quadraxial, triaxial and unidirectional fabrics, manufactured to deliver predictable, repeatable mechanical properties and excellent wet-out with Kinetix® epoxies, polyester, vinyl ester and polyurethane systems. These non-woven fabrics provide:

Excellent drapability and conformability over complex geometry
Predictable mechanical performance for consistent laminate quality
High tensile and compressive strength
Cost-effective solutions for marine and industrial structures
DNV-approved reinforcement options for commercial, defence and offshore applications

With exceptional versatility and processing reliability, ATL’s E-Fibreglass is trusted by boatbuilders, fabricators and OEMs requiring proven performance and certification-ready materials.

Fabric Orientations

Woven

Available in 200 g/m² and 290 g/m², plain weaves are ideal for:

Composite laminate construction
Skin layers
Cosmetic surfaces
Fibreglass repairs

They offer stable handling and a clean surface finish.

Unidirectional

Designed for single-direction strength, available in multiple weights.
Best for:

Beam caps
Spars
Stiffeners
Local reinforcements

Provides outstanding tensile and compressive performance along the fibre axis.

Double Bias (+45/-45°)

Available in multiple weight combinations, 0°/90° biaxial fabrics are ideal for:

Structural laminates
Panel reinforcement
Hulls and decks
Flat or lightly contoured surfaces

They deliver excellent strength in two primary directions with efficient fibre alignment for high stiffness and load-bearing performance.

Biaxial (0/90°)

Available in multiple weights, ±45° double bias fabrics are ideal for:

Torsional strength
Shear load distribution
Curved and complex shapes
Impact-resistant laminates

They conform easily to contours and provide balanced strength across off-axis loads, making them ideal for structural and secondary reinforcement.

Weft Triaxial (90/+45/–45°)

Optimised for laterally loaded laminates, providing:

Multi-direction reinforcement
Balanced stiffness and strength
Fewer layers for weight savings

Ideal for decks, panels and structural skins.

Quadraxial (0/+45/–45/90°)

Reinforcement in all major load directions.
Used when:

Load paths vary
High-performance laminates are required
Maximum mechanical efficiency is needed

Quadraxials reduce build-ups and improve structural uniformity.

Reinforcement Tapes

Available in:

Double Bias (+/–45°)
Weft Triaxial (90/+45/–45°)

Used for tabbing, bonding, stiffening and structural join reinforcement.

Designed for ATL’s Composite Ecosystem

E-Fibreglass reinforcements integrate seamlessly with ATL’s resin systems and composite products, ensuring optimal wet-out, superior mechanical properties and reliable, long-term structural performance.

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.
