Ultra-Lightweight Protection Shielding Material Against Electromagnetic Interference/Electromagnetic Pulse for Avionics

Near-peer adversaries are using the electromagnetic spectrum in a new way that has the potential to disrupt critical capabilities, such as avionics, on US weapon systems. To mitigate electromagnetic threats, new lightweight shielding materials that meet requirements and save weight are necessary to ensure warfighter competitive advantage. During the Phase II effort, Veelo will build upon the Phase I results and continue utilizing its electromagnetic environmental effect (E3) materials development experience to demonstrate a new class of shielding material that protects onboard electronics and avionics equipment from electromagnetic interference (EMI), directed energy weapons (DEWs), or electromagnetic pulses (EMPs). The technical approach will involve specialty formulated solutions from various materials that Veelo routinely processes, including but not limited to carbon nanomaterials, fine-grain metal particles, thermoplastics, and other fillers. Product forms include sheets, film, and nonwovens that can be integrated into composite laminates using various fabrication methods. VeeloÆs Phase II objective is to build upon the shielding material development, material processing optimization, and prototype naval avionics and electronics enclosure results from Phase I and Phase I Option. The enclosure prototype will have an initial design completed during the Phase I Option period with dimensions of 12öx24öx6ö. Based upon the findings of the Phase I effort, there are at least two approaches for producing the prototype enclosure: 1) a thermoset or thermoplastic carbon fiber composite enclosure with conductive mat (VeeloVEIL) interleafs or surfacer, 2) compression/press molded enclosure made from carbon nanotube (CNT)/thermoplastic fiber nonwoven sheet molding compound. A third potential approach was identified in the Phase I effort; injection molding carbon nanofiber filled PEI (Ultem) thermoplastic with an electrochemical metal plating on the surface of the injection-molded part.
