UMATEX Group makes prepregs by impregnating UMT carbon fibers or UMT-based fabrics with thermoset binder.



Prepregs made of UMT carbon fibers and binding polymer feature high strength and reduce the weight of end products.

UMT carbon fiber is a strong, elastic, and lightweight high-tech material made of polyacrylonitrile fiber.

Prepregs are differentiated by purpose: aircraft, construction, decorative, tooling, fast curing.

Physical and chemical properties of prepregs are determined by both source fiber properties and bonding matrix properties.

UMATEX Group uses different types of bonding matrices for making of prepregs to produce materials with the optimal performance depending on the purpose.
