Project Summary The ASTRID MATURATIION CARPE DIEM MAGIS project aims at developing new materials of millimeter thickness on a semi-industrial scale to absorb electromagnetic waves in the widest range within the spectral window 1-6 GHz. This project follows the ANR ASTRID CARPE DIEM project in which these materials were studied, and then developed and characterized on the laboratory scale. Applications concern the electromagnetic shielding of electronic components in the civil sphere and the stealth technology in the military field. The proposed work of maturation will first focus on manufacturing of ferromagnetic flakes of various chemical compositions in semi-industrial quantity while respecting the optimal geometric characteristics of these flakes, deduced from the CARPE DIEM project. The next stage is to disperse these flakes in an elastomer matrix using a consistent process of industrialization. The latter must allow to achieve an homogeneous flakes dispersion and maintain, within the matrix, the high degree of flakes orientation obtained on the laboratory scale. Composite plates with decimeter lateral sizes will be then fabricated. Their microwave absorption performance will be determined using free space measurements. In parallel, research activities will be conducted on micrometer-sized flakes on the laboratory scale. Lateral size reduction of flakes results in a decrease of the real effective permittivity of the composite and a change in the permeability spectrum. Interest of these micrometer-sized flakes will be evaluated in terms of microwave absorbing materials. This project is mainly an experimental work including the synthesis of composite materials and their microwave characterizations, consolidated by a modeling activity. For this work, the CARPE DIEM MAGIS project gathers 4 partners : DASSAULT AVIATION, MARION TECHNOLOGIES, PAULSTRA snc and l’Institut de Physique et Chimie des Matériaux de Strasbourg (IPCMS) with complementary skills.

DOC-3D-Ceram is an innovative training network that consists of 6 academic, 1 non-profit association and 7 industry (Large companies and SME) participants focused on CERAMICS 3D PRINTING or Ceramics Additive manufacturing applied on medical and aerospace fields. The penetration of 3D-printing processes in the ceramics industry remains low. Technology achievements remain to be done, but research activities remain low. Indeed the additive manufacturing community addresses mostly metallic or polymeric materials, and the ceramics industry lacks skilled researchers likely to exploit academic proofs of concepts to innovations. Thus training is a key challenge to support innovation in the ceramics industry and for the European competitiveness. That is why a European Training Network is the most relevant to the challenge. The training programme created for this project will be sustained after the project by associative networking. Certification and qualification evaluation of early stage researcher on this topic will be created by the consortium with the methodologies developed by NPO partner. The research methodology will be based on multi-disciplinary and inter-sectorial collaborations among the project participants. The work packages will solve each VALUE CHAIN needs: (i) Feedstock, (ii) Printer, (iii) Product, (iv) Standardisation. The expected innovations are: (i) Multi-structured and tailored materials feedstocks (ii) Printer specially designed for ceramics (iii) innovative-design ceramics products (iv) standardisation actions. From the Technology Readiness Level (TRL) point of view DOC-3D-Ceram will bridges “the Valley of death” (TRL 3 to 7) from science TRL to commercial TRL. The expected successful outcomes require a joint effort from academic and industry facilitated by the synergetic work plan proposed.

The key objective of the MEMERE project is the design, scale-up and validation of a novel membrane reactor for the direct conversion of methane into C2H4 with integrated air separation. The focus of the project will be on the air separation through novel MIEC membranes integrated within a reactor operated at high temperature for OCM allowing integration of different process steps in a single multifunctional unit and achieving much higher yields compared with conventional reactor . To achieve this MEMERE aims at developing novel, cheap yet more resistant oxygen selective membranes (target costs 30%) as compared to currently available techniques contributing to the implementation of the Roadmap and Implementation Plan for process intensification of the SET-Plan. Additionally, as air integration is integrated in an efficient way in the reactor, the MEMERE technology can be used a small scales to convert methane produced in remote areas where conventional technologies cannot be exploited.
