摘要：
In order to analyze the influence of buried position and thickness of heating sheet on the thermal conductivity of buckypaper/shape memory polymer (SMP) composites, the finite element software FLUENT is used to simulate the heating conditions of buckypaper/SMP composites, and the thermal conductivity of composites and applicability of different heating conditions is analyzed. The results showed that the maximum temperature is relatively higher, while the minimum temperature and average temperature are relatively lower for composites embedded with one layer of heating sheet. The overall temperature is lower and the temperature distribution is more uniform for composites embedded with two layers of heating sheets. The maximum temperature of composites decreases slightly and the minimum temperature rises slightly with increasing thickness of the heating sheet under the calculated conditions. It is concluded that the internal heat source per unit volume of heating sheet decreases, and the heat flux flowing through the outer surface of buckypaper and polymer matrix decreases with increasing thickness of the heating sheet. The thickness of the heating sheet has little effect on the typical temperature of composites when reaching the steady state. Copyright ©2020 Journal of Harbin Engineering University.
