具有高导热系数的碳纤维被用来提高储能介质的导热系数。研究了两种增强技术。一种是使用随机取向的纤维的技术，另一种是使用纤维刷的技术。碳纤维本质上提高了纤维/石蜡复合材料的有效导热系数。对于随机型，纤维长度对有效导热系数影响不大。纤维刷将有效导热系数提高到理论上预测的最大值。纤维刷子还可用于增强颗粒填充床的有效导热系数。
Carbon fibers with a high thermal conductivity are used to enhance the thermal conductivities of energy storage media. Two types of enhancement techniques were studied. One is the technique using randomly oriented fibers, while the other is that of using a fiber brush. The carbon fibers essentially enhance the effective thermal conductivity of fiber/paraffin composites. For the random type, the fiber length has little effect on the effective thermal conductivity. The fiber brush increases the effective thermal conductivities to the maximum values predicted which is theoretically. The fiber brush is also useful for enhancing the effective thermal conductivities of packed beds of particles.
