Lightweight fiberglass cloth (typically 18–150 g/m²) is revolutionizing industries where weight reduction, corrosion resistance, and electrical insulation are critical. Below is a technical breakdown of its applications, material innovations, and supplier landscape:
As the Chinese biggest manufacturer who is the expert in the Ultra-thin & lightweight fiberglass fabric, Changzhou Xingao Insulation Materials Co.,Ltd. is founded in 2000 year,the main product is Ultra light fiberglass cloth.
Key Properties Driving Adoption
Property | Range | Advantage vs. Alternatives |
Weight | 18–150 g/m² | 50–70% lighter than steel equivalents |
Thickness | 0.025–0.25 mm | Enables thin-section composites |
Tensile Strength | 1,500–3,500 MPa | Higher strength-to-weight than aluminum |
Corrosion Resistance | Chemically inert | Lifetime 3–5× longer than metals in harsh environments |
Dielectric Strength | 15–25 kV/mm | Critical for electrical insulation |
High-Growth Applications
1. Electric Vehicles & Batteries
Use Cases:
Battery Enclosures: 1.2–1.8 mm laminates (fiberglass + epoxy) replace steel (40% weight savings).
Motor Insulation: Slot liners (50–80 g/m² cloth) withstand 20,000+ rpm.
Material: Silane-treated E-glass (Jushi ECW300-100) with flame-retardant resin.
2. Aerospace & Drones
Use Cases:
Interior Panels: 80 g/m² cloth + phenolic resin (FST-compliant per FAR 25.853).
Drone Arms: 0.1 mm unidirectional tape (axial strength >1,800 MPa).
Material: High-silica glass (AGY Aerowave®) for radar transparency.
3. Wind Energy
Use Cases:
Blade Spar Caps: 100–150 g/m² biaxial fabrics (fatigue life >20 years).
Lightning Protection: Copper-coated glass mesh (1–5 Ω/sq surface resistivity).
Material: Corrosion-resistant AR-glass (Owens Corning Advantex®).
4. Electronics
Use Cases:
5G PCB Substrates: 30–50 g/m² ultra-low Dk/Df fabrics (Dk<4.2 @ 10 GHz).
Flex Circuits: 0.03 mm glass fabric + polyimide hybrids.
Material: NE-glass (near-zero alkali) for signal integrity.
5. Marine
Use Cases:
Sailboat Hulls: 120 g/m² cloth + vinyl ester resin (saltwater resistance).
Sonar Domes: Acoustic-transparent composites (loss <0.5 dB @ 100 kHz).
Material: C-glass (chemically resistant).
Technical Trade-Offs
Weight vs. Strength:
<50 g/m²: Ideal for electronics but limited structural use.
100–150 g/m²: Optimal for load-bearing composites (e.g., automotive).
Resin Compatibility:
Epoxy: Highest strength (use with amino-silane treated glass).
Polyester: Low cost but 30% weaker bond.
Surface Finish:
Volan finish: Best for marine corrosion resistance.
Chrome complex: Superior electrical insulation.
Changzhou Xingao is the key supplier of the above industries in China, Lightweight E-glass glass fabric is becoming the most important substrate in the composition.
