FIELD: nonwoven materials.
SUBSTANCE: nonwoven reinforced with chopped glass fiber material includes a mixture of glass fibers and synthetic fibers. Nonwoven material is obtained using a binder composition which contains a resin-based binder, a cross-linking agent and a corrosion inhibitor. Non-woven material is corrosion-resistant and resistant to volatile unsaturated monomers, such as styrene, but still remains completely compatible with solvent-containing polyester resins, which can be used in various products obtained by pultrusion.
EFFECT: disclosed is corrosion-resistant non-woven material for pipeline and applications in pultrusion.
