An ANF/mica composite insulating paper was prepared by vacuum assisted filtration and hot pressing technology taking aramide nanofiber (ANF) as matrix and natural mica (mica) as filler. The microscopic morphology, tensile strength, electrical insulation properties, and temperature resistance of the composite insulating paper were studied systematically. The results show that the mica and ANF are superimposed in order during vacuum filtration process, and the mica fragments fill the gaps in paper effectively, creating a dense "brick-and-mortar structure", which significantly enhances the electric strength and insulating properties of the composite insulating paper. Furthermore, the glass transition temperatures of pure ANF insulating paper and ANF/mica-10 composite insulating paper are higher than 300℃, exhibiting excellent thermal stability. Although the addition of mica slightly reduces the tensile properties of pure ANF insulating paper, its insulation strength and tensile performance remain superior to traditional mica paper.
