A system and related method that provides, but is not limited thereto, a thin structure with unique combination of thermal management and stress supporting properties. An advantage associated with the system and method includes, but is not limited thereto, the concept providing a multifunctional design that it is able to spread, store, and dissipate intense thermal fluxes while also being able to carry very high structural loads. An aspect associated with an approach may include, but is not limited thereto, a large area system for isothermalizing a localized heating source that has many applications. For example it can be used to mitigate the thermal buckling of ship deck plates, landing pad structures, or any other structures subjected to localized heating and compressive forces. It can also be used as a thermal regulation system in numerous applications, including but not limited to under-floor heating for residential or commercial buildings or for the de-icing of roads, runways, tunnels, sidewalks, and bridge surfaces.
