Composite components
High rigidity and low weight, as well as a high degree of integration are essential and indispensable properties of lightweight components.
Benefits of lightweight components at a glance:
- High strength and stiffness of combined with minimized weight
- Fire resistance and low flammability
- Low smoke emission and toxicity
- Resistance to environmental factors such as humidity, vibration, sand and liquids
At sea, on rail or in the air. Wherever. EFW composites
