Middle scale test on dry coatings and connections

The report of deliverable 6.1 will be split into 2 parts:The first part will present the results of the performance tests on dry coating in realistic offshore conditions and on larger samples.After the coupon level evaluations performed un WP2, several larger scale tests will be conduct. The configurations to be tested will be selected according to the WP2 outputs. Samples with and without integrated sensors will be compared as well. Recommendations for improvement of the process for both adhesive paint film and in-mold paint film will be done in accordance with the results. For emerged composite parts, a natural outdoor exposure site will be used. This consists in an exposition in open air or under shelters in a tempered marine atmosphere site. Various exposure angles can be chosen (45° south, 5° south, 90° north) and all the conditions are properly monitored. For immersed composite parts, tests in natural seawater will be conduct. The water can be regulated in temperature, oxygen and biological content. This test is performed on land and is able to give representative data on the durability and biofouling behavior of the products. The second part of the deliverable will presents the results from the static and dynamic tests performed for selected adhesive connections. Then, the reduction factors, used for a complete fatigue calculation, will be determined and presented. And finally, in the case of reversible structural adhesive, results going from the comparison with traditional adhesives until the capacity to recycle them, evaluating the heat energy and the time needed to separate the bonded joint, will be presented.
