Decarbonization and innovation: how composite materials are transforming aeronautics.
On Friday, October 17, Pierre-Jean Leduc, President of DEMGY Group, was Raphaëlle Duchemin's guest on the program Les composites au cœur des enjeux (Composites at the heart of the issues) on BFM Business.
During the interview, he shared the group's vision, its commitment to a more sustainable industry, and the innovations that place DEMGY at the heart of technological transformations. This is a wonderful recognition of French expertise in composite materials and smart polymers.
A strong strategy to respond to the climate challenge
In a rapidly changing industrial context, we are affirming our ambition: to sustainably reduce the carbon footprint of our activities and support our customers in finding ever more responsible solutions.
"We are aware that the industry must take action", says Pierre-Jean LEDUC, President of DEMGY.
This commitment is part of a broader strategy: innovating in materials, rethinking our manufacturing processes to increase automation and robotization, and actively contributing to the decarbonization of strategic sectors such as aerospace.
Composites, a major driver of decarbonization
One of the key aspects of this transformation is the use of high-performance composite materials, which can replace traditional metals in many applications.
"These materials offer significant weight savings, making aircraft more fuel-efficient" explains Pierre-Jean LEDUC.
This weight diminution directly contributes to reducing greenhouse gas emissions, a key issue for the aerospace industry.
Today, the giants of the sector have understood this well: nearly two-thirds of the mass of Airbus A350 and Boeing 787 aircraft is made up of composite materials.
These achievements demonstrate the key role of these technologies in the design of lighter, more efficient, and more sustainable aircraft.
The aircraft of the future: intelligent hybridization of materials
For DEMGY Group, the future of aeronautics lies in the controlled hybridization of materials.
“The aircraft of the future will be hybrid: composites will be used where they add the most value, alongside other materials used where they perform best,” explains Pierre-Jean LEDUC.
This pragmatic approach, focused on overall efficiency, illustrates our vision: combining technical performance, environmental responsibility, and continuous innovation.
See you at JEC World 2026
In line with this dynamic, DEMGY Group will be participating in JEC World 2026 from March 10 to 12, the global event for composites.
This will be an opportunity to showcase our latest innovations and reaffirm our leading role in the sustainable transformation of the industry.
