description: Despite the high-level guidance associated to composite structure certification already provided by existing regulations and guidance material, the registered incidents by in-service fleet and reported failures at the stage of design and development show that a deeper understanding of the different reported phenomena linked to composite structures is necessary, as well as exhaustive knowledge on the different factors potentially impacting failure and successfully tested solutions to remedy them. In light of this the Agency has decided to publish this call for tenders in order to: i) acquire a better understanding of the different sandwich structure behaviour(s); ii) (where necessary) update and enhance the current certification standards associated to sandwich structure configurations; and iii) determine potential knowledge transfer from ongoing investigations to other thin- or thick-skinned sandwich structures.
