Coriolis Composites

Coriolis Composites is a company that designs, develops and manufactures innovative equipment and software for the production of composite material structures, in particular for the aerospace market. The technology and its derivatives, protected by patents, apply to the manufacturing of aircraft fuselage made of composite materials. Coriolis Composites proven technology is qualified by major aerospace OEM for industrial production: Airbus, Safran, Premium Aerotech, Stelia and Bombardier.

Profile Description

At Coriolis Composites, we are passionate about industry and innovation. We started from scratch 20 years ago! That’s why, today, we stand as strong relays of the French Fab* and the European industry as a whole. Thanks to our history, we embrace a culture of no limits: we have carried out ambitious projects despite all the difficulties, without ever failing. Today, we master a unique combination in composite materials: machine, software & expertise. This allows us to support our customers from the beginning of their project with defining their needs and designing of the part itself, all the way to the implementation and optimization of AFP machines.


The idea of ​​Coriolis Composites was born in 1996, well before its founders, Clémentine Gallet and Alexandre Hamlyn, graduated from the engineering school. It is a real entrepreneurial adventure that has gone through all stages of development, including mountains to climb, arbitrations, phased deployment and finally, a genuine growth to become the flagship of the French composite industry.

With their sidekick Yvan Hardy, the two students, without having earned their first Euro, were convinced that their idea could revolutionize a nautical industry, which was reliant on the lightness of the composites, but the manual processes of which, left room for their ingenuity. Their project was appealing, and they soon benefitted from various grants, including the ANVAR support, material loans, access to laboratories in France and Germany allowing them to make the first prototypes and file for their first patents. They finally seduced the French Ministry of Research who consequently validated their market research study. Following a number of fund-raising attempts, their project was finally brought to life thanks to the support of the regional development fund of Brittany (France). The Coriolis Composites was created and registered in Lorient in 2000 and is still today a privately-owned company.

Creating a company means also knowing how to reorient a business model. This is what they refer as their second mountain to climb. They had the patents, the robots, but not their first client. Ultimately, it was their ability to adapt, as well as their persuasiveness, that enabled the sale of their first AFP machine to Airbus, which also meant changing their offer.

After Coriolis Composites had sold its first machine, it had to produce more in order to reassure its customers in a sector where certifications are complex and extremely demanding. It was no longer a question of conducting research but flying a plane!

The company also had to ensure recurring revenues to enable its sustainability. In 2010, Coriolis AFP cells manufactured the first nacelles for Safran. And in 2014, it produced the first structural parts for Airbus. Now, carbon can fly in constrained parts. This helped to convince the US market. The initial passion was turned into an industrial innovation with the development of a catalogue of standard and modular fiber placement robotic cells.

Having successfully climbed the three mountains, Coriolis Composites is now looking into the future and concentrates on growing as a business. As a pioneer in the adoption of robotics for materials and processes, Coriolis Composites is now emerging in new industrial markets such as the automotive industry, and new export markets in the United States and China. It is also preparing for the industry of the future by mastering additive technologies, recyclable thermoplastic materials and the connected factory software.

The story of Coriolis Composites is built on a passion shared by the founders with all employees who have gradually joined the ranks of this industrial adventure. These highly qualified, multidisciplinary and multilingual experts are a major asset of the company and are all committed to delivering exceptional customer satisfaction.
