High-strength S-glass fiber composite reinforcement bonds S-glass cloth to a host surface, forming an integral composite-and-host system that raises the bending, shear and expansion-stress capacity of the repair — meeting and exceeding the in-service requirement.
Cross-Section
The S-glass cloth is wrapped around the host pipe, then impregnated with epoxy resin. After full cure, the high-strength glass fiber and the resin form a homogeneous glass-fiber composite layer.
The composite layer exhibits strong elastic modulus, impact resistance and expansion capacity. Together with the host pipe, it carries internal pressure, dispersing stress at the defect into the surrounding composite and host wall.
Why S-Glass
Against standard E-glass, S-glass offers higher tensile strength, higher modulus, better impact resistance, better chemical stability, higher heat tolerance and better fatigue performance. For large-area pipework reinforcement at elevated temperatures, S-glass is the preferred choice — more economical than carbon fiber while still delivering engineering-grade composite performance.
