Elastomer composites with the effects of electromagnetic shielding

Abstract

The main goal of the present work is the preparation of rubber composites filled with soft magnetic lithium ferrite and metallic FeSi powder and investigation of filler influence on curing characteristics, selected physical-mechanical properties and shielding characteristics of tested systems. The study is also dedicated to the evaluation of crosslink density of prepared materials. These fillers were incorporated in acrylonitrile-butadiene rubber (NBR), which serves as a matrix. The results revealed that all measured properties of composites are dependent on the type and also on the content of soft magnetic filler.
