In this study, we investigated the effect of the embedded mode in buckypaper heating sheets and of heating power on the temperature distribution of composites reinforced by buckypaper/polymer composites in the heating process. We used the FLUENT software package to analyze the temperature distribution rule of composites reinforced by pulse⁃bending and flat buckypaper when reaching a steady state. The simulation results show that in the same heat⁃ing power conditions, the typical temperature of composites reinforced by line buckypaper/polymer composites is higher, but the temperature distribution is more uneven. The typical temperature of composites reinforced by pulse⁃bending and flat buckypaper increases linearly when the heating power increases. The heating rate of the composites reinforced by line buckypaper is higher than those reinforced by pulse⁃bending buckypaper. We conclude that the lar⁃ger the unit volume heat of buckypaper, the higher is the heating rate, which leads to a higher temperature of the composites reinforced by buckypaper when reaching steady state and a more uneven temperature distribution.%为了研究加热过程中纳米纸加热片的埋入方式及加热功率等因素对纳米纸／聚合物基复合材料温度分布的影响，采用FLUENT软件分析了矩形弯曲及平板形纳米纸／聚合物基复合材料达到稳态时的温度分布规律。模拟结果表明：相同加热功率作用下，平板形纳米纸／聚合物基复合材料达到稳态时典型温度相对较高，但是温度分布也更不均匀。加热过程中平板形及矩形弯曲纳米纸／聚合物基复合材料的典型温度均随加热功率的增大成线性增长。和矩形弯曲纳米纸／聚合物基复合材料相比，平板形纳米纸／聚合物基复合材料温度升高的速率相对更快。分析认为，纳米纸加热片的单位体积内热源越大，其升温速率越快，纳米纸／聚合物基复合材料达到稳态时温度越高，同时温度分布均匀性越差。
