Composite materials have gradually replaced metallic materials for the construction of offshore structures because they make it possible to lighten structures with comparable performance. However, their resistance in harsh environments such as the marine environment has yet to be demonstrated.


The ageing of composite materials in the marine environment is still unknown. The life duration and performance of composite materials must therefore be studied and characterized in order to develop their use for marine and EMR applications.


The ECOSAM² project aims at studying and at characterising the mechanisms of ageing of composite materials in marine and sub-sea environment in order to better estimate their lifetimes and performances for Shipbuilding and Marine Renewable Energy applications
