摘　　要：随着航空航天领域的迅速发展以及世界各国低空领域不断开放,各种无人机应用显著增多,空中环境污染问题也随之而来,各国清洁天空计划不断推进。与此同时人们对无人机本身的属性要求也越来越高,对复合材料应用提出了新的挑战。将储能电芯和超薄碳纤维复合材料相复合,制备了储能、承载一体化的结构储能碳纤维复合材料(Structural energy storage carbon fiber composite,SESCFC),对其空载和受载条件下的电化学性能进行了测试;并将其集成在自主设计的无人机机翼上,对集成后无人机的重量和续航里程进行了分析比较。结果表明:当充放电电流为0.1A时,SESCFC能量密度达到了13.2W·h/kg,功率密度达到了119.6W/kg;在1200N的载荷作用下,由于电芯正负极片间距变小,SESCFC的能量密度提高到了14.5W·h/kg。集成SESCFC后的无人机较锂电池无人机的自重减少37.5%,续航里程增加了20%;较集成太阳能电池板的无人机自重减少近20%。研究结果对于碳纤维复合材料结构-功能一体化设计及其在无人机设计中的应用具有指导意义和应用价值。With the rapid development of aerospace field and the continuous opening of low altitude areas in the world,the application of various drones has increased significantly,which results in sky environmental pollution problems,and drives many countries starting clean sky projects.Meanwhile,higher property requirements of drones pose new challenges for composites applications.In this paper,a structural energy storage carbon fiber composite(SESCFC)is fabricated by integrating energy storage core to the ultra-thin carbon fiber composite package,and its electrochemical performance is tested with and without loading.Furthermore,SESCFC is integrated into the wing of self-designed drone,and the improvement on the weight and flight endurance of the drone is evaluated.The results show that the energy density of SESCFC approaches 13.2 W·h/kg,and that the power density approaches 119.6 W/kg.Under loading of 1200N,the energy density of SESCFC increased to 14.5 W·h/kg due to space compressed between the electrodes.Compared with drones driven by Li-battery,the flight endurance of the drone with SESCFC increases 20%,and the self-weight decreases 37.5%.Compared with solar panel-driven drones,about 20%lightweight effect has been achieved.The results are helpful for structure-function integrated design of carbon fiber composites and their application in drone design.
