The GdR FIBMAT (CNRS GdR 2139) focuses on fibrous materials made from synthetic, natural, or recycled fibers. While not exhaustive, the targeted applications include textiles, soft, intelligent, and functional structures, biomaterials, as well as reinforcements for composites and biological tissues.

In this context, the aim of this GdR is to bring together the various mechanics communities working on these materials, with the goal of understanding and identifying their mechanical behavior, optimizing their architectures, considering the origin of the fibers, and mastering the manufacturing processes of materials based on these fibrous structures—all while taking into account the inherent couplings related to the intended applications.

The GdR’s work will rely on the expertise of the network's partners, through experimental, theoretical, and numerical approaches, at the various scales of these architectured materials. The GDR Fibmat is carried by Pierre Dumont (Lamcos), Damien Soulat (Gemtex) and Peng Wang (LPMT) and is structured around four thematic axes.

Thematic axes and animators:

• Axis 1: Mechanics of ordered or disordered fibrous media and intelligent, multifunctional soft materials.

  Animators: Samir Allaoui (ITheMM), Federica Daghia (LMPS), Nahiene Hamila (IRDL), Peng Wang (LPMT)

• Axis 2: Thermo-hygro-mechanical couplings and flows in fibrous media.

  Animators : Monica Pucci (LMGC), Chung Hae-Park (CERI MP), Pierre Dumont (LaMCoS), Steven Le Corre (LTEN).

• Axis 3: Structure and mechanics of bio-based and recycled natural fibers.

  Animateurs: Alain Bourmaud (IRDL), Nicolas Le Moigne (C2MA), Florina Martoïa (LaMCoS), Vincent Placet (FEMTO), Damien Soulat (GEMTEX).

• Axis 4: Mechanics of soft biological tissues and fibrous materials for biomedical applications.

  Animateurs: Nadia Bahlouli (ICube), Lucie Bailly (3SR), Pauline Lecomte (LaMcube), Frédéric Heim (LPMT).

   

A GdR week, bringing together all the members of the GdR FIBMAT, is organized each year to promote exchanges and discussions and to take stock, as well as prospects, actions carried out during the previous year.

The GdD FIBMAT Week 2025 is organized by the ITheMM (UR 7548), research unit of the University of Reims Champagne-Ardenne (URCA), in the premises of EiSINe in Charleville Mézières.
