Composites and syntactic foam

BMTI is specialised in composite materials and structures dedicated to deep-water applications.

The company offers protective parts (radomes), the structure of which has been optimised to resist water pressure (up to -1,000 m) and repeated shocks from "heavy sea".

It also offers a wide range of syntactic foam offering excellent buoyancy in depths of up to more than 8,000 m. These materials are available in blocks and in the form of standard buoys.

The “composite” activity harnesses all key aspects of the technology available to it and has a considerable array of R & D and production resources.

  • Mechanical studies:
    - 3D computer aided design (Solid Works)
    - Finite element calculations
    - Isotropic and anisotropic materials (composites)
    - Non-linear calculation, damped structures
    - Shock and vibration design
  • Development of chemical formulations:
    - Epoxy & polyurethane bases
    - Exothermic control, adaptation of the cure cycle, control of glass transition temperature (Tg)
  • Test and control:
    - Differential scanning calorimetry
    - Complete "laboratory" range (mixers, etc.)
    - 600 bar pressure test chamber (automatic cycling)
  • Manufacture of models and moulds
  • Casting and machining
  • Plastic film deposition and finishing
