After 46 months of R&D, the ACDC project (Advanced Composites for Acoustic and vibration Damping Control) has reached its goal: developing innovative composite materials and structures to reduce noise and vibrations in aircraft nacelles and cabins. These innovations aim to enhance passenger comfort, ensure compliance with acoustic standards, and pave the way for a more sustainable aviation industry.

The project has delivered its results: partially bio-based thermoplastic panels, 3D vibration filters, and acoustic structures—all tested and validated to minimize noise and vibration levels.

This project was conducted in collaboration with Airbus, Metacoustic, Porcher Industries, Bysco, Groupe SDTech, Continental Tech, Institut Clément Ader (ICA) CNRS UMR 5312/ISAE, ONERA – The French Aerospace Lab, and the Graduate School of Acoustics.

Key Results:

✔️ 1 patent pending: A unique innovation in acoustic composites for nacelles and cabins.

✔️ 2 scientific publications: Sharing breakthroughs in 3D “absolute filter” structures.

✔️ Over 10 matured innovations: Next-generation sandwich panels, vibration filters, and insulating materials.

These innovations are clearing the path for a quieter, more comfortable, and more sustainable future for flight.
