Abstract

Dielectric or magnetic anisotropy layers, laminated composite material incorporating said layers and their production process. The laminated material has at least two stacks of assembled layers, a first stack constituted by a layer (2) of first dielectric fibers (4) oriented parallel to a first direction (x), and a layer (6) of first magnetic fibers (8) oriented parallel to a second direction (y) perpendicular to the first direction (x), and a second stack constituted by a layer (10) of second dielectric fibers (12) oriented parallel to the second direction (y), and a layer (14) of second magnetic fibers oriented parallel to the first direction (x). Each fiber is constituted by a thermoplastic polymer sheath containing a pulverulent magnetic or dielectric charge.
