Polymers and Composites

Our teams support your R&D department in obtaining polymers and composites that are resistant, lighter, of higher quality and eco-designed. We combine our expertise in heat transfer, mechanics and materials and develop custom test benches.

Our laboratory and on-site analyses and tests provide detailed understanding of your materials: thermosetting polymers, thermoplastics, semi-crystalline, fiberglass and carbon fiber composites.

Advanced characterization of polymers and composites

Detailed understanding of the structure and properties of polymers, thermoplastics, and composites to optimize your final products or explain their failures

  • Structural analysis: microscopy, rate of polymerization, crystallinity, molecular orientation of polymer chains
  • Chemical analyses: nature and proportion of components (EDX, DRX, DSC, TGA, etc.) and surfaces (XPS, FTIR, etc.)
  • Thermal analyses: phase changes, degradation, oxidation, dilatation, pyrolysis
  • Mechanical analyses: hardness, density, fatigue, aging
  • Assessments: failure analysis, aging, reverse engineering, non-destructive testing

Thermal analysis of materials and manufacturing processes

Analyzing the thermal properties of your solid and liquid materials in the laboratory or on site, under conditions closest to the process

  • Volume and thermal expansion: PVT measurements for thermosetting polymers and thermoplastics, chemical shrinkage, evolution of a resin’s thermomechanical properties
  • Kinetic models: identifying parameters, polymerization, crystallization, vulcanization, kinetic reactions of glues
  • Conductivity, effusivity, diffusivity: thermal resistance, thermal conductivity of anisotropic composite materials
  • Rheology: viscosity of reactive systems, rheograms, measurements on complex fluids

Concrete on Cruise Ships

On each ship deck designed by Chantiers de l’Atlantique, layers of concrete are poured before the flooring is fitted. The contractors who apply these layers use different cementitious materials that have different properties – which can pose problems during application. To improve this stage of shipbuilding, the shipyard commissioned experts in geomaterials and civil engineering structures from Capacités to conduct a comparative study of sev…
