Industrial Corrosion Resistant Biaxial & Multiaxial Fiberglass Fabric for Composite Reinforcement

        Our Biaxial and Multiaxial Fiberglass Fabric is a high-strength E-glass reinforcement designed for wind turbine blades,marine structures,FRP pipes,chemical tanks,automotive components,infrastructure,and other demanding composite applications. Unlike conventional woven fiberglass cloth,the continuous E-glass rovings are laid in controlled directions such as ±45° or 0°/90° and stitched together with polyester yarn without interlacing the structural fibers.This non-crimp fiberglass fabric structure keeps the primary reinforcement fibers relatively straight,providing efficient directional reinforcement,good resin penetration,and stable fiber orientation for structural composite manufacturing.Standard grades include 400–1200 g/m² biaxial fiberglass fabrics,while customized constructions from approximately 200–2000 g/m² and widths from 100–2600 mm can be supplied according to laminate requirements. Compatible with unsaturated polyester,vinyl ester,and epoxy resin systems,the reinforcement is suitable for vacuum infusion,RTM,hand lay-up,and other FRP manufacturing processes.

Key Advantages of Biaxial & Multiaxial Fiberglass Fabric

1. Non-Crimp Fiber Structure

Unlike traditional woven fiberglass fabric,biaxial and multiaxial fabrics arrange continuous glass rovings in controlled directions without weaving the primary reinforcement fibers over and under each other.

The layers are held together with polyester stitching yarn.

This structure reduces fiber crimp and helps the continuous rovings maintain a straighter load path through the composite laminate.

2. Controlled Fiber Orientation

Fiberglass axial fabrics can be engineered with different fiber orientations according to structural requirements.

Common configurations include:

• +45° / -45°

• 0° / 90°

• Customized Multiaxial Orientations

By selecting the appropriate orientation,composite designers can place reinforcement in the directions where mechanical loads are expected.

3. High Directional Strength

Straight continuous fiberglass rovings provide efficient reinforcement along their designed fiber directions.

This makes biaxial fiberglass fabric suitable for structural composite components requiring controlled tensile,shear,and torsional reinforcement.

Actual mechanical performance depends on fiber orientation,fabric weight,resin system,fiber volume,laminate design,and manufacturing quality.

4. Excellent Shear Reinforcement with ±45° Fibers

±45° biaxial fiberglass fabric is particularly useful for composite structures exposed to shear and torsional loads.

The opposing +45° and -45° reinforcement layers distribute loads diagonally across the laminate.

Typical applications include wind turbine blade skins,shear webs,boat hulls,decks,surfboards,and other dynamically loaded composite structures.

5. Balanced 0°/90° Reinforcement

0°/90° biaxial fiberglass fabric provides reinforcement along two perpendicular directions.

This construction is suitable for composite structures requiring balanced longitudinal and transverse strength.

Typical applications include FRP pipes,chemical tanks,transportation components,and structural panels.

6. Good Resin Wettability

The non-crimp structure provides open paths between fiberglass rovings,allowing compatible resin systems to penetrate through the reinforcement.

Good resin wet-out is particularly important for vacuum infusion and RTM applications where resin must travel through the dry reinforcement stack.

Actual resin flow depends on fabric construction,laminate thickness,resin viscosity,vacuum level,and infusion strategy.

7. Optional Chopped Strand Mat Layer

Selected biaxial fiberglass fabrics can be combined with an additional chopped strand mat layer.

The current product range supports optional chopped mat layers from approximately 50–500 g/m².

This creates a multifunctional reinforcement combining directional continuous fibers with randomly distributed chopped fiberglass.

8. Suitable for Corrosion-Resistant FRP Structures

Fiberglass axial fabric can be incorporated into corrosion-resistant FRP pipes,tanks,chemical equipment,and marine structures.

When combined with an appropriate vinyl ester,epoxy,or other corrosion-resistant resin system,the reinforcement can form part of a durable composite laminate for demanding industrial environments.

Corrosion resistance should always be evaluated based on the complete fiberglass-resin laminate system.

9. Wide Customization Range

Biaxial and multiaxial fiberglass reinforcements can be customized according to structural and manufacturing requirements.

Available variables can include:

• Total grammage

• Individual layer grammage

• Fiber orientation

• Fabric width

• Chopped strand mat backing

• Roll length

• Resin compatibility

• Application-specific reinforcement structure

Biaxial & Multiaxial Fiberglass Fabric Applications

1. Wind Turbine Blades

Biaxial fiberglass fabric is widely used in wind energy composite structures.

Different fabric weights and reinforcement orientations can be combined according to blade size,structural design,and vacuum infusion requirements.

2. Boat Hulls & Marine Structures

±45° biaxial fiberglass fabric is suitable for boat hulls,decks,bulkheads,and other marine composite structures.

The diagonal fiber orientation provides reinforcement for complex loading conditions commonly experienced by marine structures.

Biaxial fiberglass reinforcement is particularly suitable for vacuum-infused marine laminates.

3. FRP Pipes & Pipe Linings

0°/90° fiberglass fabric can be used in FRP pipes and selected pipe lining systems.

The orthogonal fiber structure provides reinforcement along both longitudinal and transverse directions.

The exact fiber orientation should be selected according to pipe diameter,internal pressure,external loads,and laminate design.

4. Chemical Storage Tanks

Biaxial and multiaxial fiberglass fabrics can be incorporated into corrosion-resistant FRP chemical tanks and process equipment.

Vinyl ester or another appropriate corrosion-resistant resin system should be selected according to chemical type,concentration,temperature,and service environment.

8. Industrial Composite Components

Multiaxial fiberglass reinforcement can be customized for industrial equipment,machinery covers,structural laminates,large molded components,and other FRP products requiring engineered fiber orientation.

±45° Biaxial Fiberglass Fabric

±45° biaxial fabric consists of two continuous fiberglass roving layers positioned at approximately +45° and -45°.

The layers are stitched together using polyester yarn without weaving the primary structural fibers.

This construction is especially useful for:

• Shear reinforcement

• Torsional loading

• Complex structural laminates

• Wind turbine blade skins

• Wind blade shear webs

• Marine hulls

• Deck structures

• Chemical tanks

• Structural panels

• Transportation components

• Automotive parts

• Infrastructure composites

• Industrial FRP equipment

Technical Specifications by Grade

The listed values should be used to compare individual product grades within the current range. Final reinforcement selection should also consider laminate design,resin system,fiber volume,and finished composite mechanical requirements.

Biaxial Fiberglass Fabric with Chopped Strand Mat

Selected fiberglass axial fabrics can be manufactured with an integrated chopped strand mat layer.

For example,EBX800/225 combines:

• +45° Fiberglass Layer – 400 g/m²

• -45° Fiberglass Layer – 400 g/m²

• Chopped Strand Mat – 225 g/m²

• Total Nominal Weight – 1025 g/m²

This hybrid structure combines directional biaxial reinforcement with randomly distributed chopped fibers in a single reinforcement material.

It can be useful for complex molds and multilayer FRP structures where both directional and random reinforcement are required.

Resin Compatibility

Not every product grade has the same listed resin compatibility. Resin selection should therefore be confirmed according to the specific axial fabric model and manufacturing process.

Biaxial Fiberglass Fabric for Vacuum Infusion

Biaxial fiberglass fabric is particularly suitable for vacuum infusion applications because the non-crimp reinforcement structure combines controlled fiber orientation with efficient resin penetration.

During vacuum infusion,dry fiberglass reinforcement is positioned inside the mold and sealed under a vacuum bag. Resin is then drawn through the laminate using vacuum pressure.

For successful infusion,manufacturers should consider:

• Fabric grammage

• Number of reinforcement layers

• Fiber orientation

• Resin viscosity

• Resin inlet position

• Vacuum level

• Flow media

• Laminate thickness

• Mold geometry

• Target fiber volume

The reinforcement structure should be selected as part of the complete infusion system rather than independently.

How to Choose the Right Fiberglass Axial Fabric

For shear or torsional reinforcement,±45° biaxial fabric is generally the more relevant starting point.

For balanced longitudinal and transverse reinforcement,0°/90° biaxial fabric can be considered.

More complex loading conditions may require customized multiaxial reinforcement structures.
