Applications

Weaving on Dornier works

Reinforcement of carbon composite plates  

 > Defense & Security

• Individual protective clothing, pilot aircraft and tanks shields.
• Advanced fuel tanks.

 >  Aerospace

• Stiffening of panels under compressive loads.

 > Sailing

• Large rigid and wrench-proof unfurlable sails.

 > Civil Engineering

• Anti seismic protection of buildings, bridges and roads.
• Awnings with acoustic improvement

 >  Textiles

• Adaptive clothes variable shape and tightening capabilities.

Keywords

• Nitinol, Textiles, Panels, Shape control, Damping, Ballistic protection.

Advantages

• Materials by design: Properties mainly governed by alloy composition.
• High force and strain capabilities.
• Life time enhancement of conventional composite structures.
• Damping and energy absorption capabilities.

Testing

• At various temperature from LN₂ cryogenic temperature to 300°C:
  • Conventional mechanical tests – Tensile & bending…, in static, dynamic, fatigue
  • Unconventional specific tests - Tear, vibration, impact, perforation, explosion

• Facilities:

  • Specimen instrumented with adapted sensors.
  • Fast data acquisition systems.
  • Tensile static and dynamic machines.
  • High speed actuators.
  • Crash tower.
  • Bullet ballistic installation.
  • Compressed air gun.

Expertise

• Over 3 years of experience in collaboration with ENSAIT Roubaix and industrial partners from Club Tex in the below areas with accompanied characterisation and evaluation tests:
• Present weaving capability of numerous hybrid products
• Further development of various 2D and 3D texture
