Fiberglass fabric is a woven reinforcement material made from glass fiber yarns, known for its light weight, high strength, heat resistance, and corrosion resistance. Commonly used with resins like epoxy or polyester, it plays a key role in applications such as boat building, construction reinforcement, automotive parts, thermal insulation, and mold making. Thanks to its strong and stable woven structure, fiberglass fabric is ideal for both structural performance and surface finishing in composite materials.
Chopped strand mat, often referred to as fiberglass mat, is a non-woven reinforcement material made from randomly distributed chopped glass fibers, held together by a binder. It offers excellent resin absorption, uniform strength in all directions, and is easy to shape and handle—making it ideal for hand lay-up, spray-up, and molding processes. You’ll find this material commonly used in automotive components, boat hulls, mold backing layers, and a wide range of fiberglass reinforced plastic (FRP) products.

Choosing between fiberglass cloth and mat depends on your project’s needs. If you want high strength and a smooth finish for visible or structural parts, fiberglass cloth is the better choice. For quick resin absorption, easier handling, and cost savings in non-visible layers.
Objet | Tissu de fibre de verre | Tapis en fibre de verre |
|---|---|---|
Typical Applications | Hulls, wind turbine blades, structural parts, high-strength areas | Models, surface layers, filler layers, cost-sensitive areas |
Advantages | High strength and dimensional stability Neat and smooth appearance Ideal for layered structures Reusable in molds | Fast forming process Low cost Easy to handle, suitable for beginners Conforms well to curves and corners Fast resin absorption |
Limitations | Higher cost Less flexible for complex shapes | Lower tensile strength Rougher surface finish |
Fiberglass cloth is widely used in manufacturing fiberglass boat hulls due to its high tensile strength, corrosion resistance, and smooth finish. It is also essential in fiberglass boat repair, helping restore structural integrity and appearance. The cloth’s fine weave is suitable for producing smooth fiberglass sheets used for inner wall panels, consoles, and decks.
Fiberglass mat is commonly used for sub-deck construction and in areas like the fiberglass mat for boat floor. It offers fast laminate build-up and vibration damping. Mat is also often layered beneath fiberglass cloth or fiberglass sheets to add thickness and reinforce internal structures such as bulkheads, lockers, and under-deck panels.
Material Type | Weight (g/m²) | Thickness (mm) | Tensile Strength (warp/weft, MPa) | Resin Content (%) | Remarks |
|---|---|---|---|---|---|
Tissu de fibre de verre | 200–300 | 0.25–0.35 | 2000 / 1900 | 30–40 | High strength, smooth finish, UV resistant |
Tapis en fibre de verre | 450–600 | 1.0–1.5 | 800–1000 (non-directional) | 45–55 | Good vibration damping, thick lamination |
Fiberglass cloth is applied where surface quality and stability are critical—such as EIFS systems, drywall reinforcement, and decorative panels. It is also laminated onto fiberglass sheets for high-end wall claddings and ceiling boards where appearance and performance matter.
Fiberglass mat is favored for waterproof membranes, structural sheathing, and fire-resistant boards. When combined with fiberglass sheets, it enhances crack resistance, insulation, and impact strength in partition walls, wall linings, and utility-grade reinforcements.
Material Type | Weight (g/m²) | Thickness (mm) | Tensile Strength (MPa) | Resin Content (%) | Remarks |
|---|---|---|---|---|---|
Tissu de fibre de verre | 160–280 | 0.2–0.3 | 1700–2100 | 30–40 | Fire retardant, moisture resistant |
Tapis en fibre de verre | 300–550 | 0.8–1.4 | 700–900 (multi-directional) | 40–50 | High resin absorption, crack resistance |
Used in outer layers of wind turbine blades, fiberglass cloth provides superior formability and aerodynamic performance. It also appears in high-strength fiberglass sheets used in solar panel frames and wind tower enclosures.
Mat supports blade cores and inner layers by delivering multidirectional strength and fatigue resistance. It’s frequently used in fiberglass reinforced plastics for sustainable energy structures and laminated with fiberglass sheets to reduce production time while improving mechanical properties.
