Our experts offer a complete range of engineering, development and characterisation of materials.
The skills of our teams are combined with the expertise and exceptional technical resources of research laboratories from Université de Nantes (France). We use a broad range of measurement and testing equipments including almost 220 devices. This enables us to offer a wide variety of tests and analyses dealing with the different properties of materials: physical-chemical, structural, mechanical, optical, thermal, etc.
This engineering and characterisation offer applies to all types of materials: metallic, polymer and composite, organic, cement and ceramic. Thus, we provide a global, reactive and local offer in response to your technical issues and innovation projects regarding materials and their performance.
The forming processes and conditions of use of metallic materials and alloys are interdependent on their properties. Our materials engineers develop and perform the pertinent tests to determine the properties of your materials or the cause of their failure in order to optimise the choice of materials or manufacturing processes.
Expertise – Failure
From the reliability of surface preparation processes to the inspection of welded, bonded or coated assemblies, our experts will help you to control and improve your current processes. Understanding the phenomena at the interfaces is essential to address industrial issues related to assembly of materials and perfomance of coatings.
Functional materials and surface treatments
Surface texturing and functionalisation expertise
Process qualification : cleaning / degreasing / bonding / painting
Polymer metallisation – substitution of Chromium(VI)
Characterisation of coated surfaces and assemblies
We identify the structure and properties of your polymers and thermoplastics. The aim: to optimise your manufacturing processes, improve your finished products or explain their failures. To do this, we carry out physico-chemical analyses and assess your products at the various stages of their shaping or use.
Thermal instrumentation and multiphysics modelling
Durability and aging of composite materials
Reuse and recycling
Advanced characterisation for additive manufacturing
With the support of IMN researchers, our materials experts identify and characterise solid and powdered ceramic materials and determine their physical, chemical and structural properties. Our engineers have the necessary experience to carry out investigations in order to understand the possible failures of ceramic materials.
Chemical and microstructural analysis
Expertise – Failure
Whether you are in the pre-certification phase or during the construction phase, our tests determine the mechanical and physico-chemical properties of your materials, in the laboratory or on site. Our equipment enables us to characterise a wide range of properties: strength, thermal insulation, permeability, etc.
Characterisation of concrete
Formulation of resistant concretes in the marine environment
Development of low-impact concretes
Durability of concrete structures
Mechanical testing of concrete
Concrete pathology expertise
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…
A leading aeronautical equipment manufacturer turned to the experts at Capacités to assist in completing the final stages in the development of their novel composite material.
A key player in the aeronautics sector called on Capacités’s specialists to determine the thermal conductivity properties of a composite material reinforced with short fibers during the injection process.
As part of its R&D activities, Liebherr Aerospace sought to measure, up to 400°C, the thermal conductivity of a thermal barrier coating, deposited in a thin layer on an aluminium substrate.
