Rigidity, mechanical behavior and weight are critical for any material used in aerospace and aircraft applications.

Composites are used in:

- primary structural parts (flaps and aerosoils, propellers and air brakes)
- small plane fuselages
- helicopter shells and rotor blades
- aircraft secondary structural parts (floors, doors, seats, air conditioners, secondary tanks)
- airplane motor parts

Composites are also used in a variety of civil and military security applications:
- mine sweeper hulls
- helmets
- radomes
- rocket nozzles
- rescue stretchers
