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 most widely used in aircraft engineering. Other applications include:

Specifications of prepregs made of UMT carbon fibers

Surface fiber density (FAW) Content of binder Type of fiber Glass transition temperature (Tg) Reinforcement
100-600 g / sq. m from 25% carbon fiber, fiberglass and aramid fiber 90-200 °C unidirectional, biaxial and multiaxial fabrics

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.
