Plasan Group

Since 2004, AMEFO works together with the PLASAN group, world leader in protection and survivability systems (land and airborne vehicles, vessels, individual protections)

This technological partnership has led to the integration of AMEFO into the PLASAN group in 2012

AMEFO/PLASAN offer innovative solutions to solve survivability issues faced by their clients

AMEFO and PLASAN create and maintain close relationships with their key innovation partners as research institutes and university laboratories specialized in creating new stronger and lighter materials.

AMEFO/PLASAN combine their simulation and testing resources to develop new products and guarantee their quality against any type of threat (IED, mines, EFP, ammunitions etc.).




Enhanced by 70 years of experience, AMEFO has developed skills in various complementary tasks and built its reputation in France and abroad:

  • Conception and industrialization (CAD Tools: Catia, Solid Edge, Ansys)
  • Cutting and bending

  • Special steels welding

  • Machining

  • Assembling and mounting

  • Paints and coatings

  • Composite and ceramic parts manufacturing

Organizational skills

Tailor made quality services are ensured by efficient and recognized work organization methods. AMEFO interacts with its partners at each stage of the project and provides full transparency of its operations:

  • Project mode

  • Simultaneous engineering

  • Study/validation/prototype

  • In-house production

  • On-site maintenance

Ballistic research & development

AMEFO’s R&D team independently develops steel and composite based armor solutions complying with the “Special France” requirements and NATO classifications. Lighter and leaner, those solutions optimize its production level and can be more easily integrated inside the vehicle.

AMEFO relies on its research discoveries that are evaluated in European testing centers such as the national test facility of Saint Etienne, TNO testing facilities in Hollande etc.

AMEFO uses PLASAN’s computing and testing resources if necessary:

Ballistic test facilities:

  • 2 shooting tunnels, 30m long

  • Testing capacities from 9mm to 30mm calibers

  • Slow motion cameras with X ray imaging system

  • Environmental test chambers

Mines and IED blast testing:

  • Reduced scale tests on specific parts or entire vehicles
  • Vehicles test’s instrumentation: accelerometer, anthropomorphic mannequin

Materials characterization and their method of assembly:

  • Static tests: bending, traction, compression, cutting
  • Dynamic tests: planar impact test, split Hopkinson pressure
  • Physicochemical characterization: Differential Scanning Calorimetry (DSC), infrared spectroscopy


  • LS Dyna: Materials and vehicles behavior modeling to study ballistic impacts or mine/IED blast blowing effect

  • Condat: vehicle area protection coverage

Etudes de mécanisme de pénétration balistique / Ballistic penetration mechanism simulations
Etudes de dispersion des projectiles avec Liner anti-éclat / Ballistic projection dispersion with anti-spall liner simulations
Test de protection contre les mines et IED / IED and mine blast protection simulation
