Fabienne Touchard is currently a Senior CNRS Researcher at PPRIME Institute, ISAE-ENSMA (Poitiers, France). She graduated as Mechanical and Aeronautical Engineer at ISAE-ENSMA in 1991. She got her PhD at the University of Poitiers in 1994 on the mechanical behavior of carbon/epoxy and carbon/PEEK composite materials, in collaboration with the AIRBUS Research Centre (Paris, France). She was hired as full time Research officer at CNRS in 1996. Fabienne Touchard is specialized in the field of microstructural and mechanical properties of polymers and polymer composites. Her research focuses on the characterization and optimization of interfacial adhesion quality, especially in natural fiber composites and 3D printed composites. She has authored and co-authored over 70 peer-reviewed journal articles. She has directed or co-directed 16 PhD theses. She has been responsible for 25 collaborative research programs Fabrizio Sarasini received the Laurea degree (cum laude) in Materials Engineering and the Ph.D. degree in Materials Engineering from Sapienza University of Rome in 2002 and 2007, respectively. Since June 2019 he is Associate Professor of Materials Science and Technology at the Department of Chemical Engineering Materials Environment of Sapienza University of Rome. His research interests include the use of plant fibres in biopolymers for designing biocomposites with reduced environmental impact, fibre/matrix interfacial modification and assessment, the valorization of agro-industrial wastes as fillers in thermoplastic matrices (micro- and nanoscale), 3D printing of polymers and polymer matrix composites, the low and high velocity impact response of composite materials for structural applications. He has directed or co-directed three PhD theses and has been responsible for four collaborative research programs. He has more than 160 international peer-reviewed journal papers.
