Polyalcohol has poor heat conduction performance. A fiber-enhanced polyalcohol binary system combines polyalcohol with a copper fiber net to improve its heat conduction performance. In a binary system without fibers, more heat input increases the wall temperature near the container than when the fiber is present. Compared to a polyalcohol binary system, pentaerythritol/Tris hydroxymethyl aminomethane (PE/TRIS) without fibers, fiber-enhanced polyalcohol system PE/TRIS shows quicker response to energy input from the exterior region. The phase change temperature in a fiber-enhanced polyalcohol binary system is much lower than that in a polyalcohol system without fibers. This is because of the metastate plastic state that presents a nonfaceted phase interface with a larger radius of curvature in a polyalcohol system without fibers. The porous structure of the fiber is smaller than the size of the phase interface in a polyalcohol system without fibers and can increase the equilibrium pressure and make the phase change easier.
