abstract While the aim of composites is to replace metals in various applications, researchers are involved in improving not only the mechanical but also the electromagnetic and thermal properties of polymeric composites. Also, it is known that filled poly- meric composites show interesting properties especially when the fillers are nanosized. In such conditions it is expected that laminate composites formed with filled epoxy will show different properties. These are the results of a trail-and-error study regarding the influence of fillers on the electrical (at first) and mechanical properties of reinforced composites with filled epoxy matrix. Two types of fiber fabric were used as reinforcements and ferrite, talc and CNT were used as fillers. 250 mm long, 120 mm wide and 5-7 mm thick plates of composites were formed in glass moulds. Electrical standard tests and three point bending standard tests were performed.
