Test Overview
Nantong Drayson Composite Materials Co., Ltd. has recently completed a comparative load test on its pultruded FRP heavy deck (601×72×12.3×14.7 mm) using two resin systems: Isophthalic Polyester (ISO) and Epoxy Resin. The goal was to evaluate the decks' ultimate strength, stiffness, and failure behavior under identical test conditions. The results clearly demonstrate the superior mechanical performance of the epoxy-based pultruded deck in structural applications.

Key Findings
• Superior Strength: The epoxy pultruded deck achieved 69% higher ultimate load capacity.
• Greater Stiffness: Deflection decreased by about 20%, improving structural rigidity.
• Enhanced Ductility: Epoxy exhibited a progressive and safer failure mode.
• Improved Energy Absorption: The epoxy deck absorbed nearly 1.8× more energy before failure, ensuring better long-term safety margins.
Conclusion
Drayson's Epoxy Pultruded FRP Deck sets a new benchmark in mechanical strength and structural safety. Its high stiffness, enhanced toughness, and superior fatigue performance make it ideal for marine, bridge, and industrial decking applications - especially where safety and load reliability are critical.
