Conference | Biobased Composites in Marine Environment

22/ avr.

organised by University of South Brittany


Registration Open - 22-23 april 2021, on line

Due to the ongoing health situation, the Biobased Composites in Marine Environment Conference will be 100% online. The Organisation Committee is currently working on finding the best virtual platform to ensure as much interactions as possible between the participants. More information will come soon. 

After two previous editions organised by the partners INRAE Nantes and University of Portsmouth, University of South Brittany is the third partner of the FLOWER project to host this “Biobased Composites in Marine Environment Conference” that will highlight scientific work and industrial initiatives on the integration of biocomposite materials in maritime sectors.


This third event on 22-23 April 2021 will be dedicated to the use of biobased materials and composites in the marine environment. These research areas are directly linked to the scientific axes of the CNRS IRDL institute, organiser of this event (see organisers section for more details). It is also in strong relation with the topics studied in the FLOWER project; in particular through the development of a foiler boat, fully flax fibres reinforced as well as biobased and compostable advertising panels are developed.

In Lorient, this topic takes on its full meaning, as the city has always been related to the oceans.  Founded in 1666 to be the national headquarters of the Compagnie des Indes, Lorient is entirely focused on maritime activities by hosting one of the main French military arsenals, as well as the largest French fishing port in terms of value. Lorient has also been able to diversify by becoming France's leading centre for competitive sailing and ocean racing. All this has earned it the nickname of "city of 5 ports".



During the two days of the conference, the following topics will be discussed:

  • Plant fibres and preforms for biobased composite materials: Degradation of plant fibres in the marine or water environment; Hygroscopic behaviour of plant fibres and reinforcements; Influence of the nature and specificity of the plant fibres; Innovative preforms; Ageing of plant fibres and associated reinforcements.
  • Matrices and interfaces: Ageing; Durability; Evolution of interfaces; Behaviour and degradation of matrices in immersion, relative humidity or marine environment; Biobased matrices; Behaviour in a marine environment, degradation and biodegradation; Modelling and prediction of service life.
  • Biobased composites in the marine environment, in-use properties: Water ageing of biodegradable or biobased composites; Mechanical, vibratory and fatigue behaviour; Extreme stresses; Submerged structures; Biodegradation of parts; Controlled biodegradation; Biobased composite applications for Renewable Marine Energies.
  • Deconstruction, end of life, recycling and environmental assessment of biobased composites: Recycling of matrices; Recovery; Deconstruction; Life Cycle Analysis; Eco-design; Recycling of parts at the end of life; Deconstruction / separation of components.


Biobased Composites in Marine Environment Conference, organised by University of South Brittany (IRDL Laboratory), is the third to be held within the framework of the FLOWER project (co-financed by the Interreg VA France (Channel) England Programme); following two editions organised by the INRAE in Nantes in 2019 and the University of Portsmouth in 2020. Both were dedicated to the structure and properties of plant fibres and the performance and properties of the associated composites. During the webinar organised by the University of Portsmouth, an important place was also given to industrial applications.
