Multifunctional material systems MfMS are materialsystems that can perform more than one primary function simultaneously or sequentially in time to enhance system-level performance through the elimination of redundancy between sub-system materials and functions. A system-level performance metric of considerable importance is energy performance and efficiency. Total energy usage in 2009 by US Department of Defense DoD has been estimated at 900 trillion BTUs with approximately 75 of that being consumed for mobility related applications e.g., aircraft, ships, vehicles, etc.. This paper describes the development of a new class of multifunctional laminate composites with controllable surface morphology at NRL. The current focus is on two-phase solid-fluid, thin, flexible, skin-like laminates with surface pore arrays that are connected to an internal vascular network. These new materials with structural skin surface morphology control multifunctionality are being called poro-vascular composites or PV composites for short.
