Disclosed is a polyester flame-retardant core for prefabricated panels, which is remarkably improved in compression strength and bending strength through a foaming process of a flame-retardant material treated to polyester floss. Further, a method of manufacturing the polyester flame-retardant core, including treating polyester floss with a foamable flame-retardant material to allow the foamable flame-retardant material to be stuck between fibers of the polyester floss, followed by drying, and foaming the foamable flame-retardant material stuck between the fibers of the polyester floss by heating. The thus obtained flame-retardant core can exhibit superior compression strength and bending strength, even with a low density. Hence, the flame-retardant core can be economically manufactured and easily handled and constructed, and can improve in heat-insulating properties or weather resistance, on account of foaming properties thereof.
