Fiberglass Fabric 101: Types, Applications, and Selection

Fiberglass fabric is a reinforcement textile made from glass filaments, woven or stitched into fabric form and combined with resin to produce composite laminates. It is used in marine, wind energy, transportation, UAV, sports, industrial, and tooling applications where high strength-to-weight ratio and corrosion resistance are required. This reference guide explains the two fiberglass fabric families manufactured by Guangdong Cinon New Material Technology Co., Ltd. (CINON)—Light Weight Fiberglass Cloth and Multiaxial Fiberglass Fabrics—and provides a step-by-step framework for selecting the right reinforcement.

CINON is a manufacturer of fiberglass reinforcements and lightweight core materials based in Guangzhou, China. Established in 2022, the company operates a 40,000 m² manufacturing facility with an annual production capacity of 1,200,000 m², an R&D team of 25 engineers, and approximately 20 staff. CINON exports 100% of its production to Europe, North America, and Asia-Pacific markets.

Why Fiberglass Fabric Selection Matters

Composite parts fail or exceed budget when fiberglass fabric is selected by price or habit instead of engineering requirements. Four variables must be matched to the application:

• Areal weight (g/m²) controls laminate thickness and resin uptake per ply.
• Fabric architecture controls directional strength, stiffness, and drape.
• Glass type controls chemical resistance and long-term durability.
• Process compatibility determines whether the fabric wets out reliably in hand layup, vacuum infusion, RTM, or VARTM.

When these variables are mismatched, laminates can become resin-rich and overweight, fibers can distort and reduce strength, or infusion can stall and create dry spots. A documented selection process reduces these risks.

Fiberglass Fabric Industry Background

The global fiberglass fabric market was valued at USD 14.01 billion in 2024 and is projected to grow to USD 25.65 billion by 2033 (Grand View Research). Woven fiberglass fabrics accounted for 48.62% of market revenue in 2025, supported by their critical role in yacht hulls and automotive panels (Mordor Intelligence). Asia Pacific contributed 41.61% of global revenue in 2024, driven by infrastructure and renewable energy projects (Grand View Research).

Among application segments, the wind energy segment is expected to grow at a CAGR of 8.5% from 2025 to 2033, the highest among all fiberglass fabric application segments (Grand View Research). Wind turbine blades account for approximately 42.5% of total fiberglass usage within the wind energy sector (Dataintelo). In the marine sector, the fiberglass resin market is projected to reach USD 4.23 billion by 2033, indicating steady demand for fiberglass fabric reinforcements for ship hulls and decks (Market Research Future).

Key global players in the fiberglass fabric market include Owens Corning (US), China Jushi Co. (China), Saint-Gobain (France), and Taishan Fiberglass (China) (MarketsandMarkets).

Two Fiberglass Fabric Families from CINON

1. Light Weight Fiberglass Cloth — E-Glass, Plain Woven

Light Weight Fiberglass Cloth is a fiberglass fabric classified as E-Glass Fabric and made of E glass fiber. It features a plain woven weave type, with a weight range of 25–400 g/m² and widths of 1000 mm or 1010 mm. The plain weave provides conformability and a smooth surface finish, with good resin absorption and easy lamination.

Light Weight Fiberglass Cloth is intended for use in Marine & Yacht Building, Surfboard Manufacturing, UAV & Drone Manufacturing, Sports Equipment, Industrial Composites, Composite Tooling, Wind Energy, and Transportation. The fabric is used for lightweight composite reinforcement, marine composite reinforcement, vacuum infusion reinforcement, and surface finish fabric.

2. Multiaxial Fiberglass Fabrics — Non-Crimp, Structural

Multiaxial Fiberglass Fabrics are structural composite reinforcements classified as Non-Crimp Fiberglass Fabric, made of alkali free glass fiber. They are available in unidirectional (0° or 90°), biaxial (0°/90° or +45°/−45°), triaxial (+45°/0°/−45° or +45°/90°/−45°), and quadriaxial (0°/90°/−45°/+45°) orientations.

The weight range is 400–1500 g/m², with moisture content less than 0.2% and combustible matter content between 2.0% and 8.0%. Because the fibers are stitched rather than woven, they remain straight, which reduces fiber crimp and improves load distribution. These fabrics are designed for use in vacuum, hand layup, extrusion, RTM, and other formed products, including ship hulls, wind turbine blades, automotive components, sports equipment, and large containers.

Multiaxial Fiberglass Fabrics are intended for Marine & Yacht Building, Wind Energy, Transportation, Industrial Composites, Infrastructure, Sports Equipment, and Defense Applications.

Step-by-Step: How to Choose the Right Fiberglass Fabric

Step 1 — Define the application and loading direction. A boat hull experiences multi-directional loads; a UAV wing is loaded primarily in one direction; a wind blade shell faces long-term cyclic loading. The load case determines whether a plain woven fabric or a multiaxial non-crimp fabric is appropriate.

Step 2 — Select the fabric architecture. Plain woven E-glass cloth (25–400 g/m²) provides drape, smooth surface finish, and suitability for lightweight laminates, surfboards, UAV structures, composite molds, and surface finish layers. Multiaxial non-crimp fabrics (400–1500 g/m²) provide straight fiber alignment and improved load distribution for structural laminates in ship hulls, wind turbine blades, automotive components, and large containers.

Step 3 — Match areal weight to the laminate schedule. Lighter fabrics (25–150 g/m²) add surface quality and low weight; heavier fabrics (200–1500 g/m²) build laminate thickness efficiently. Multiaxial fabrics from 400 to 1500 g/m² are used in vacuum, hand layup, extrusion, and RTM processes.

Step 4 — Confirm process compatibility. For vacuum infusion, resin infusion, and VARTM, Multiaxial Fiberglass Fabrics have moisture content below 0.2% and combustible matter between 2.0% and 8.0%, supporting stable resin flow. Light Weight Fiberglass Cloth is also used as a vacuum infusion reinforcement and surface finish fabric. In marine manufacturing, vacuum infusion and resin infusion are standard operation modes for boat hulls and marine panels.

Step 5 — Verify supplier capability. Confirm the supplier's manufacturing capacity, R&D resources, and export experience. CINON operates a 40,000 m² facility with an annual production capacity of 1,200,000 m² and an R&D team of 25 engineers, serving Europe, North America, and Asia-Pacific markets.

FAQ

Conclusion

Fiberglass fabric is an engineered reinforcement, not a commodity. Matching areal weight, fabric architecture, glass type, and process compatibility to the application is the difference between a reliable laminate and a costly rework. CINON covers the two most common fiberglass fabric requirements: Light Weight Fiberglass Cloth (plain woven E-glass, 25–400 g/m²) for lightweight laminates and surface finish, and Multiaxial Fiberglass Fabrics (non-crimp, 400–1500 g/m²) for structural reinforcement in vacuum infusion, RTM, and hand layup.
