A study on thermal conductivity of nickel-coated carbon fibers/graphite flakes/polyethylene composites |
| 초록 |
In this work, hybrid fillers, such as carbon fibers (CF) and graphite flakes (GF), were employed to prepare highly thermal conductive polymer (HDPE matrix) composites. In order to increase good thermal conductivity of the composites, an electroless nickel plating technique on carbon fibers were used as a function of metal content. The nickel-coated carbon fibers with various metal content were prepared in 1.0 inch size, and reinforced with 20 phr in all composite samples by a compression molding technique. The content of graphite flakes were fixed at 20 phr as a thermal additive. From the results, we observed that the mechanical properties and thermal conductivity of the nickel-coated CF/GF/HDPE were enhanced with metal content on the fibers. This result indicates that metal coating on the fibers can act like a heat gate between GF and CF resulting in a decrease in the thermal loss of the composites. |
