Hexcel HexForce Fiberglass S-Glass Plain Weave 3.6oz/123gsm Style 4522 F81 Finish

Hexcel HexForce Fiberglass S-Glass Plain Weave 3.6oz/123gsm – Style 4522 F81 Finish

Hexcel HexForce Style 4522 is a premium S-glass plain weave fiberglass fabric designed for demanding composite applications where higher strength and durability are required without sacrificing low weight. At approximately 3.6oz (≈123gsm), this cloth offers excellent stiffness, impact resistance, and fatigue performance compared to standard E-glass, making it ideal for advanced, weight-conscious structures.

The balanced plain weave construction provides uniform mechanical properties in both the warp and fill directions, a smooth surface, and predictable drapability for clean, stable layups. The proven F81 finish delivers reliable compatibility with epoxy, vinyl ester, and polyester resin systems, ensuring fast wet-out and strong fiber-to-resin bonding in high-performance laminates.
