3. Reinforcement of UD-tapes and fabrics
Especially designed High Performance Polymers
for applications in Composites
made from epoxi-resins and
- Carbon fibers
- Mineral fibers (Glass, Basalt)
- Polymer fibers (Kevlar, Aramide)
- Natural fibers

4. Properties
Stabilising of unidirectional filaments
multiply, woven and knitted fabrics
nonwovens
⇒ Better and easier handling
⇒ Antifray
⇒ Gluing of multiple layers to one component
⇒ Production of preforms without additional auxiliaries
