Evaluation of Epoxy Resin Composites in Multilayer Structure for Stealth Technology

Abstract

The present work evaluates a multilayer structure based on epoxy resin for stealth technology. The structure consists of two absorber layers with nanoferrite and a resistive layer between them containing polyaniline (PANI) with and without carbon nanotube (CNT). The best reflection loss result multilayer structure analyzed was Ni-PANICNT-Fe with RL = –22dB at 11,9 GHz, justified by higher conductivity loss due to the CNT in PANI epoxy composite
