The objective of this study is to improve the energy efficiency for an car seat heater utility by developing a new concept of a heating sheet. The advantages are in fields of pollution prevention, economics, and productivity. The effect of electroless Ni-plating on electrical conductivity and surface temperature of glass, PAN, and pitch-based carbon fibers was investigated. The surface and structural properties of the carbon fibers were determined by scanning electron microscope (SEM) and X-ray diffraction (XRD), respectively. The electrical conductivity was obtained by measuring the surface resistance with 4-pin probe method. The thermal properties of the carbon fibers were studied by thermal conductivity measuring system. |
