About us

Our company

Composites et Technologies is a design office located in Châteaudun (28), Eure-et-Loire.

Our name represent our know-how :

Composites, because we wind carbon composite tubes. Their weight and strength allow us to use them as a basis in applications with high stresses. These include drive shafts resistant to torque-induced torsion, fluid tanks for laboratory use that are resistant to high pressures and temperatures, and hollow tubes resistant to crushing.

Technologies, because we design machines that meet specific needs. Based on the study of the request and the specifications, we develop a solution to solve the customer's problem.

We handle every step of your project :

  • Study.
  • Design.
  • The choice of the products needed.
  • Assembly.
  • Wiring
  • Programmation
  • Validation by acceptance test report, through testing of each subsystem.
  • Commissioning, to ensure that the proposed solution functions properly.

Our vision

Innovation is what drives us. Motivated by the challenges of new projects, we gain expertise and refine our methods to maintain a versatility that allows us to expand our areas of expertise.

We therefore address our clients' needs with a broad perspective, unrestricted by our areas of expertise alone.

We are constantly studying to improve ourselves, because we believe that mastery is the key to success.
