Polymer Matrix Composites for Electromagnetic Applications in Aircraft Structures

Abstract

The paper gives a short technical appreciation of some of the critical requirements of polymer composite materials in aircraft structures, beyond their well known specific strength/stiffness driven applications. In this regard, it focuses on certain important electromagnetic properties of the composites commonly used in aircraft structures, with specific references to microwave transparency, electromagnetic interference (EMI) shielding and microwave absorption applications. The paper presents a short theoretical overview on each of these applications and narrates the status of research and development activities pertaining to these domains.
