We offer the whole range of textile reinforcing materials made from high-quality carbon, glass, and aramid fibers, impregnated with different resin systems.
Our SIGRAPREG woven, non-woven, unidirectional, and multiaxial fabric prepregs are state-of-the-art reinforcing materials. They are fatigue- and corrosion-resistant and have excellent mechanical properties that make it possible to produce stiff, strong yet ultra-lightweight fiber-reinforced composites. We can tailor the prepregs perfectly to your requirements, since we formulate our own state-of-the-art resin systems and are equipped with many different production and processing options for reinforcing materials. Additionally, we offer compatible adhesive films which are used e.g. for aerospace and industrial applications.
- Excellent mechanical properties
- Low density
- Low thermal expansion
- Good electrical conductivity
- Own resin formulation for individual resin systems
- Low laminate thickness tolerances possible
Our SIGRAPREG TowPregs are pre-impregnated fiber bundles made from carbon or glass. With TowPregs, better results for challenging processes can be achieved. Our material not only gives components very good mechanical properties. They also have excellent winding behavior that permits far more uniform placement to the highest accuracy, provides constant width and therefore excellent processing behavior.
- Constant resin content, tack level, and tow width
- Easy processing saving time and cost
- High winding accuracy for better mechanical properties
- Environmental and health friendly
- Stabile storage at room temperature
