Hexcel HexForce Fiberglass S-Glass Plain Weave 5.6oz/190 gsm Style 4533 F81 Finish

Hexcel HexForce Fiberglass S-Glass Plain Weave 5.6oz/190gsm – Style 4533 F81 Finish

Hexcel HexForce Style 4533 is a premium S-glass plain weave fiberglass fabric engineered for applications where maximum strength and fatigue resistance are required without adding unnecessary weight. At approximately 5.6oz (≈190gsm), this cloth delivers significantly higher tensile and flexural performance than standard E-glass, while maintaining excellent handling and drapability.

The balanced plain weave construction provides uniform properties in both directions and a smooth surface suitable for structural and cosmetic laminates. The proven F81 finish is designed for outstanding compatibility with epoxy, vinyl ester, and polyester resin systems, ensuring reliable wet-out and strong fiber-to-resin bonding in demanding environments.

Key Features

• High-performance S-glass – typically 25–30% stronger than comparable E-glass fabrics.
• 5.6oz (≈190gsm) weight for excellent strength-to-weight efficiency.
• Plain weave for stable handling, consistent fiber distribution, and clean layups.
• F81 finish optimized for epoxy, vinyl ester, and polyester resins.
• Improved impact, fatigue, and tensile performance for critical composite structures.
• Manufactured by Hexcel for tight quality control and repeatable results.
• Standard width of 30 inches for efficient coverage in high-performance builds.

Typical Applications

• High-performance marine structures, sailing hardware, and performance hull laminates
• Masts, spars, and components requiring superior stiffness-to-weight
• Aerospace and UAV structures where durability and low weight are critical
• Motorsport panels, impact zones, and energy-absorbing structures
• Sporting goods (paddles, sticks, boards, frames) needing elevated mechanical properties
• Localized reinforcement or hybrid layups with carbon or aramid fibers
