Abstract
The regulation of temperature within living and storage spaces in high-temperature environments is a demanding challenge mostly met using high-fuel consuming air conditioning systems. Phase-change material (PCM) systems have the potential to decrease military operating costs and ease operating demands. By passively regulating temperature cycles through absorbing heat during daytime and releasing heat during nighttime, PCM systems can decrease the need for conventional air conditioning systems. The aim of this research was to encapsulate a PCM into an epoxy resin, which would be applied to fabric for use as a lining in living or storage spaces. Nonadecane, an organic hydrocarbon with a melting temperature of 32°C and sufficient cyclability, was selected as a suitable PCM material. The epoxy-PCM composite was manufactured using the thickening agent Carbopol to aid in the emulsification of PCM and epoxy. Various micro- and nano-scale thermally conductive additives were included into the composite formulations to improve thermal performance. Using 3D printing strategies, the new epoxy-PCM composite system was successfully attached to fabric to create a removable liner.
