The ability to create conductive composite using NanoMaterial can potentially change Boeing’s approach to lightning strike protection, electromagnetic shielding and heat dissipation. NanoMaterials, imbedded in composites structure, would eliminate the need for complex and heavy protection and shielding systems and would help maximize the potential of composites for aerospace applications. Nanostrands are introduced into the matrix (resin) and the paint and are coated to the fiber to create or improve conductivity. Their unique properties set them apart in their abilities to easily form highly conductive three-dimensional sub-micron and NanoStructured lattices. In addition, the metals of which they are formed are inherently magnetic, thus they can be aligned, resulting in tailored conductive and possibly mechanical properties. The presentation will provide an overview to nickel NanoMaterials for use in lightning strike protection and shielding and will discuss the recent test results using Nickel NanoMaterials. The presentation will also include a discussion on manufacturing issues, and health and safety issues. Future applications of NanoMaterials beyond conductive composites such as flame retardancy, composite performance enhancement and hydrophobicity, will be also be discussed.
