Research of Influence Factors of Thermal Properties of Composites Reinforced by Nanopaper

The finite element software FLUENT is used to analyze the heating power and shapes of nanopaper on the thermal property of composites reinforced by nanopaper. The temperature cloudy maps of the polymer composites reinforced by pulse bending nanopaper shows the greater the heating power, the higher the maximum temperature along the section of z=0. At the same time, it can be observed that the high temperature region gradually expanded and gradually reached a stable process during the heating process. The curve of the ratio of heat loss to the total heat loss of Q(total) by convection heat dissipation on the outer surface of polymer matrix composite reinforced by pulse bending and flat nanopaper shows that, with the increase of heating time, the increase of the external surface temperature makes the convection heat dissipation increase, so the proportion of the total heat consumption of Q(total) is gradually increased. The research shows that the proportion of heat lost by convective heat dissipation in pulse bending and flat nanopaper is slightly different, and the proportion of heat lost by convective heat loss of pulse bending nanopaper is relatively larger than that of the total heat consumption.
