High-Performance Glass Fibre

Product Overview

HiPer‑tex® is 3B’s flagship high-performance glass fibre, offering a step change in composite reinforcement through advanced glass formulation and sizing technology. It achieves higher strength, stiffness, and fatigue resistance while remaining cost-effective compared to other high-performance fibres.

Key Benefits

• ~25–30% Higher Tensile Strength
  Delivering tensile strengths of 2,700–3,200 MPa, compared with 2,000–2,600 MPa for standard E‑CR glass

• ~17% Higher Modulus
  Demonstrates a modulus of 86–91 GPa, versus 74–83 GPa for traditional E-glass 

• ~45% More Strain Energy & 10× Improved Fatigue Performance
  Exhibits superior energy absorption and durability under cyclic loading 

• High Corrosion & Thermal Resistance
  Produced without boron or fluorides—softening point ~925 °C, CTE ~30% lower than E-glass, and excellent chemical and acid resistance

• Outstanding Impact Resistance
  V50 tests show higher resistance compared to E-glass, approaching S2-Glass levels

Technical Highlights

• Softening Point: 925 °C (vs 886–904 °C E‑glass) 

• Density: ~2.58 g/cm³, similar to E‑CR glass 

• CLTE (0–300 °C): ~4.1×10⁻⁶ K⁻¹ (E‑glass: 5.4–6) 

• Tensile Strength: 2,700–3,200 MPa 

• Modulus: 86–91 GPa 

• Strain at Break: 3.1–3.3% 

• Sizing: Epoxy-compatible (e.g. W2020), as well as polyester and vinyl ester grades (W3030)

Variants & Applications

• W2020 Roving: Tuned for epoxy thermosets; certified by DNV GL for wind turbine blades; offers superior shear and fatigue performance

• W3030 Roving: Tailored for polyester, vinyl ester, and epoxy—optimised for prepreg, NCF, filament-winding, and pultrusion 

• H2020 Roving: Used in high-pressure composite cylinders (e.g., CNG bottles), achieving ~50% weight savings over steel; certified to ECE R110

Key Applications

• Aerospace & Defense: Impact/ballistic protection, armour panels, V0-rated phenolic laminates.

• Wind Energy: High-modulus blades with enhanced service life and corrosion resistance; certified by DNV GL.

• High-Pressure Cylinders: Poletech CNG bottles, lightweight gas storage with 40–50% weight savings.

• Sport & Leisure: Lighter skis (5–10% savings), high-strength sporting goods.

• General Structural Composites: Ideal for pultrusion, filament-winding, prepreg, and NCF production. Strong thermo-mechanical performance across applications
