| Abstract: | In this paper,the temperature distribution of the copper particles uniformly dispersed in the PTFE matrix composites and the relations between the effective thermal conductivity of PTFE-based composites and copper content were analyzed by using ANSYS parametric finite element analysis.In addition,the simulated results were also compared with the corresponding experimental results.The results show that the copper content have a significant influence on the thermal performance of PTFE-based composites.The relationship between copper content and thermal conductivity of the composites is near linear.And the simulated results are very close to the experimental results,indicating the reliability of simulation results.The results of this study can provide a good reference for the design and application of PTFE-based composites. |
