The invention belongs to the technical field of carbon fiber composite materials, and particularly relates to a cobaltosic oxide/carbon fiber composite material, and a preparation method and an application thereof. The preparation method of the cobaltosic oxide/carbon fiber composite material comprises the following steps: (1) taking water as a solvent, adding cobalt nitrate and urea, stirring toobtain a rose solution, continuously adding carbon fibers, and reacting to obtain cobalt hydroxide/carbon fibers; and (2) taking the cobalt hydroxide/carbon fibers as a precursor, and calcining to obtain the cobaltosic oxide/carbon fiber composite material. The cobaltosic oxide/carbon fiber composite material prepared by adopting a two-step method not only has excellent conductive and magnetic conductivity, but also maintains the characteristic of light weight, solves the problems of poor magnetic performance and poor low-frequency protection performance when the existing carbon fiber is usedas a resin composite material, and is suitable for being used as a composite material of a railway vehicle body and a key part.
本发明属于碳纤维复合材料技术领域,具体涉及一种四氧化三钴/碳纤维复合材料及其制备方法与应用。所述四氧化三钴/碳纤维复合材料的制备方法,包括:(1)以水为溶剂,加入硝酸钴与尿素,搅拌,得到玫瑰色溶液;继续加入碳纤维,反应得到氢氧化钴/碳纤维;(2)以氢氧化钴/碳纤维为前驱体,煅烧,得到四氧化三钴/碳纤维复合材料。本发明采取两步法制得的四氧化三钴/碳纤维复合材料,既具有优异的导电导磁性能,又保持了轻量化特点,解决了现有碳纤维用于树脂复合材料时磁性能差、低频防护性能差的问题,更适用作轨道车辆车体及关键部件的复合材料。
