Marine Aging of Polymers, 28th-29th August 2019, Brest, France
The overall objective of this colloquium is to establish the state of the art in both the knowledge and prediction of the mechanical response of polymers and composites in a marine environment and to propose new research orientations.
There are increasing quantities of polymer-based materials being used in marine structures. These range from thousands of composite pleasure boats to the hundreds of tons of offshore oil and gas pipe insulation, but in all cases their useful service life is limited by the effects of the marine environment on the mechanical performance of the polymer.
Marine aging factors include sunlight for surface vessels, and hydrostatic pressure for deep sea applications but the main specificity in all cases is seawater. Many studies have focused on interactions between seawater and polymers over the last 50 years but new combinations of materials and more extreme service conditions (deeper water, higher temperature) require more reliable predictive tools than the simple experience-based safety factors used to date.
This requires new, improved models of mechanical response and more realistic experimental test facilities to validate them. It is also essential to include coupling effects between water and mechanical loads, and work on these is at an early stage. The overall objective of the colloquium is to establish the state of the art in both the knowledge and prediction of the mechanical response of polymers and composites in a marine environment and to propose new research orientations.
The colloquium will address the following topics
1. Polymers and elastomers
2. Foams and syntactic foams
3. Polymer fibres
4. Fibre Reinforced polymers
Each session will include between four and six papers, followed by a discussion period. Presentations by young researchers and PhD students will be actively encouraged.
The specific aims of the colloquium are the following: First, to bring together leading European experts in the area of polymer aging to discuss the specific problems associated with the influence of the marine environment on mechanical behaviour. Second, the issues associated with coupling between water diffusion and mechanical loads will be highlighted, as this is a key area in the development of predictive models and is receiving considerable current attention.
The colloquium will be held during the same week as the CFM conference in Brest, but attendees of the colloquium will not be obliged to pay the full fee for the CFM.
