Heat transfer of polymers and composites
Vincent Sobotka
Professor at the University of Nantes, member of the LTeN team for “Thermal Transfers in Materials and at Interfaces,” Scientific manager at Capacités.
His research activities focus on the thermal science of polymer and composite forming and concern three complementary areas:
Heat Transfer and Energy Laboratory at Nantes (LTeN)
LTeN is a heat transfer research unit that is recognized nationally and internationally, as well as in the industrial sector. The laboratory has two research areas: transfers in fluids and energy systems and thermal transfers in materials and at interfaces.
The Thermal Transfers in Materials and at Interfaces Team
The main objective of the team’s research is to understand and control heat transfers occurring inside materials and during their development or forming processes.
Scientific publications
More than 220 pieces of industry-specific equipment
Our team has a rich and varied fleet of machines at its disposal. We make sure to utilize the most suitable technical means for each project. To do so, we design specialized test benches that are tailored to polymers, resins or composites representative of each process.
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.
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.
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.
Capacités teams inspire, harness and couple numerous cutting-edge skills covering a wide range of applications and expertise to meet all of your innovation needs with passion and commitment!
