In this study, a non-woven fabric type planar heating element using carbon fiber and PE was manufactured; material analysis and surface resistance analysis were conducted; and temperature characteristics by voltage were analyzed according to the content ratio by using EVA, an insulating material. Surface resistance measurement and power consumption measurement indicate that, as the number of carbon fibers increases, the contact area between fibers increases and the flow of current improves.
In addition, the temperature rose and holding time increased through insulation. However, the thermal uniformity decreased. Further, while there was a section wherein the contact area between carbon fibers increased, there was also a section wherein the contact area relatively decreased according to a random shape.
