Viper-Skin™Carbon Fiber Composite Reinforcement System
The first biaxially, hybrid carbon and glass fiber polyurethane prepreg system that blends the
unsurpassed strength and stiffness of carbon with the ease of use of a moisture-cured prepreg.
PRODUCT INFORMATION
Viper-Skin™ is the first biaxially, hybrid carbon and glass fiber polyurethane prepreg system that blends the unsurpassed strength and stiffness of carbon with the ease of use of a moisture-cured prepreg. This carbon
fiber reinforcement composite system uses a factory-controlled, wet-out process. As a result, nearly perfect resin content and maximum, repeatable strength properties are attainable. The time and cost associated with field wetting of the composite is removed from the equation altogether and the moisture-curing properties allow for underwater and wet environment applications. The Viper-Skin solution conforms to all shapes, welds, and irregular geometries, and one size can be used on a variety of pipe diameters.
The Viper-Skin system provides a cost-effective solution by:
- Eliminating field mixing and wetting of the composite system to ensure proper fiber-to-resin content ratios that are crucial to reliable performance.
- Combining simplicity with flexibility to permit application to irregular shapes and geometries, thereby reducing parts inventory.
- Incorporating proprietary load transfer and bonding technology results in a high-tensile wrap capable of repairing pipes and pipelines beyond their original bursting strength.
