NORPLY™
NORPLY™ is a cured epoxy composite material based on a unique non-woven, parallel filament construction. This type of construction minimizes filament stress abrasion that can shorten fatigue life in conventional reinforced plastics. NORPLY™ uses type E continuous filament fiberglass. It is supplied as cured flat panels or cut to size shapes.
Features and benefits:
- High impact strength
- High strength-to-weight performance
- Low notch sensitivity
- Resistant to cleaning fluids and solvents
- Weight reduction
- Chemical and corrosion resistance
- Excellent fatigue life and high strain capability
- Less downtime in harsh environnements
- Greater capacity to store energy thant 1060 spring steel
NORPLY™ is available in unidirectional, cross-ply or isotropic fiber orientation, each offering a different balance of physical propterties.
