Weight Optimized Mitigation to Direct Effects of Lightning Strike on a Missile Body Using Filament Winding Techniques

San Diego Composites (SDC) proposes the use of advanced composite materials with tailored electrical properties in conjunction with the filament winding manufacturing process to provide a light-weight, reliably and repeatably manufactureable lightning protection system that will expand with motor operating pressures and integrate seamlessly with composite parts. In the Phase I program, SDC proposes to select the lightweight lightning mitigation material candidates, to design a rocket motor cases (RMC) with continuous conductivity for lighting strike mitigation, and filament wind representative RMC test articles that will be lightning strike tested to quantify performance of each lightning strike mitigation material. The technology insertion focus will be new Ground-Based Interceptors (GBIs) and future GBI upgrades. Based on experience, affiliations, and capabilities, SDC is well positioned to develop and deliver RMCs with integrated lightning protection systems.
