Among the extreme loads to which composite structures such as ship hulls and sonar domes can be subjected, wave impact and underwater explosions are prominent. The complexity of the phenomena involved is their rapid dynamic nature, the localized overpressures they generate and the fluid / structure coupling effects they imply, during the shock phase and beyond. The structures concerned are rarely tested at sea or in basins and their dimensioning is increasingly dependent on the use of digital simulation tools. Even if the maturity of these tools and their level of validation make it possible to consider that they serve as a reference, their implementation in a design office is hardly compatible with the cost and time constraints of projects, at least. in the pre-sizing phase. In addition, the objective of reducing safety coefficients (and therefore manufacturing costs) requires detailed knowledge of damage mechanisms, their modeling and their quantification, in order to correctly feed the digital models dedicated to design. As a continuation of the SUCCESS project, this project aims to develop and validate an approximate sizing method for each type of loading, slamming and underwater explosion, taking into account the fluid / structure interactions, the directional behavior of composite materials and by facing advanced methods and testing. The "simplified" nature of these methods must allow their implementation in a design office, and this from the preliminary design phase. The specific work concerning the prediction of the type of damage generated in the composite structure aims to increase their potential, by accepting so-called degraded states compatible with the expected performance.

The composite materials market is rapidly expanding, based on the excellent performance of epoxy resin composites. However, this aromatic thermoset, in addition to being of fossil origin, cannot be recycled. Lignin, the most abundant aromatic biopolymer available on earth, is a promising alternative. The use of lignin in materials is very limited due to its complexity and unsuitable properties. The ReCoLV project therefore aims to develop new 100% biosourced matrices containing high levels of lignin through clean, efficient and affordable modification of lignin with biosourced reagents. The cross-linking of this matrix providing durability and excellent mechanical properties will be ensured by an innovative vitrimer network of dynamic covalent bonds to obtain recyclable and repairable composite materials.

NanoFabNet – International Network for sustainable industrial-scale Nanofabrication The NanoFabNet Project will create a strong international hub for sustainable nanofabrication, whose structure, business model and detailed strategies and action plans are designed, agreed and carried by its international stakeholders during the Project duration, in order to yield an (economically) self-sustaining collaboration platform: the NanoFabNet hub. The registered NanoFabNet membership organisation will provide an accountable, permanent secretariat to the hub; it will be responsible for the implementation of a long-term business plan, and the provision of validation services, trainings and consultations, while collaborative and cooperative activities between actors of the wider international nanofabrication community will be fostered within the open architecture of the hub, and may be supported by membership organisation, where necessary. The hub will stand for (a) a well-implemented, guided approach to high levels of safety and sustainability, (b) trusted technical reliability and quality, and (c) compliance with and drive of harmonisation, standardisation, and regulation requirements, amongst all of its members and along their nanofabrication value chains. It is envisaged to have a complex, open structure, whose elements will be developed, agreed and validated in a step-wise approach to meet the high-level objectives outlined below. The achievability of these aims to be a one-stop-shop for all matters and concerns pertaining to sustainable nanofabrication and its successful incorporation into the complex, large-scale high-value industries by bringing together governmental and academic laboratories with large industries and SMEs, and thereby offering a coordination space for past, current and future collaborative nanofabrication projects (incl. both EU-funded projects and initiatives, as well as public-to-public partnerships (P2Ps) and public-private-partnerships (PPPs)).
