Description
Hexcel® HexForce® S2-Glass — 8-Harness Satin (8HS) · 8.92oz (≈302gsm) · Style 6781 · F81 Finish · 50" Width
Build lighter parts without giving up toughness. Hexcel® HexForce® Style 6781 is a premium S2-glass reinforcement in an 8-Harness Satin (8HS) weave. Compared with standard E-glass, S2-glass delivers significantly higher tensile strength, compressive strength, impact resistance, and temperature capability—ideal for advanced, high-performance laminates. The 8HS construction provides outstanding drape over complex shapes and creates a tight, smooth cosmetic face. The F81 silane finish promotes fast wet-out and durable adhesion with common thermoset resin systems.
Key advantages
- S2-Glass performance: higher strength and toughness than E-glass for demanding applications.
- 8HS drape & surface: conforms easily to tight radii and leaves a smooth, paint/clear-coat-ready finish.
- Versatile areal weight:8.92oz (≈302gsm) works well as a skin, intermediate ply, or as the final cosmetic layer.
- F81 silane finish: engineered for excellent bond with epoxy and compatible with polyester & vinyl-ester systems.
- Hexcel quality: consistent fiber alignment and weave uniformity for predictable processing and results.
Typical uses
High-performance skins and panels, racing & powersports components, marine parts, UAV/airframe skins, protective hybrid layups with carbon fiber (for improved impact toughness), and any laminate requiring a premium glass outer ply.

How We Sell
We sell this fabric by the linear yard. You will receive a continuous piece of fabric at the width listed.
For example, if the fabric is 50" wide, a quantity of 1 (linear yard) equals a continuous piece measuring 50" wide × 36" long. A quantity of 5 (linear yards) equals a continuous piece measuring 50" wide × 180" long.
