Lightweight components

Sandwich panels have been used in modern aircrafts and transportation solutions for many years already. High rigidity and low weight, as well as a high degree of integration are essential and indispensable properties of 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
