Conclusions(1)The feasibility of the finite PF-477736 simulation method presented in this paper is verified through experiments and the commonly used prediction models introduced by predecessors.(2)A systematic study is conducted on the effect of graphite particles size, graphite filled volume fraction, and its distribution on thermal conductivity of the PTFE composites. And 250-mesh graphite has better modification effect than other size particles.(3)A prediction model of thermal conductivity of PTFE composites filled with carbon fibers is presented.(4)The optimum volume fraction matching is introduced. The results indicate radiometric time the optimum volume fraction matching is 17.76 and 10% for volume fraction of graphite particles and carbon fibers, respectively.AcknowledgmentThe authors are grateful to the China Postdoctoral Science Foundation funded project (Grant Nos. 201104400 and 2014M552011) for financial support.
