The foundation of this study lies in the intriguing engineering practice of material multifunctionality. The control of multiple characteristics of a material allows its use in fields in which several properties are essential to ensure up-to mark performances. To analyse the objective of multifunctionality, in this case declined in the EM behaviour associated with the mechanical one, an experimental campaign of test was developed alongside a numerical investigation. The experimental study is divided into several step, from the production of materials to their mechanical and EM characterization. The tested materials are thermosetting polymer matrix composites reinforced with fillers that belong to two different families: organic (BC) and hybrid (Fe@BC).
