Zyvex Technologies (Columbus, OH, US) has launched ZNT-boost, an epoxy-composite toughening system based on carbon nanotubes (CNTs) for carbon and glass fiber composites that brings the benefits of increased toughness without compromising the strength and stiffness of the composite. Zyvex says that ZNT-boost doesn't force the user to compromise on one property to increase another. ZNT-boost reportedly increases the toughness of the composite up to 100% while increasing the stiffness and strength up to 30%. In addition, says Zyvex, ZNT-boost can be used with standard composite processing systems and reportedly is the simplest way to leverage the benefits of carbon nanomaterials. No process changes need to be made and no changes are required in catalysts or curing agents when using ZNT-boost. It is available in two forms: liquid and dry flake (powder) for most epoxy-based composite applications that include prepreg, vacuum-assisted resin transfer molding (VARTM), infusion and hand layup. ZNT-boost works with most epoxies, vinyl esters and polyesters.
