The effects of nanofiber and fibrid with their amount on the structure and properties of paper were studied in detail， and the reaction mechanism of which was also discussed. The results showed that the paper formation， mechanical strength and electrical insulation strength of para-aramid nanofiber paper were better than fibrid paper. With the content of nanofiber or fibrid at 40% in paper， the tensile and tear indexes of para-aramid nanofiber paper were 44% and 57% higher than those of fibrid paper， respectively. Moreover， the electrical breakdown strength of para-aramid nanofiber paper increased 80%. The difference was mainly due to the higher surface activity of para-aramid nanofibers， resulting a good machinability and secondary assembly performance.]]> 2022/11/21 0:00:00 DONG Zhirong,CHEN Yuexi,LIU Yutian,TIAN Wei,ZHANG Yunkui,YAO Kuncheng,TUO Xinlin 3true -8 cm³/J. Compared with dopamine pretreatment， the nitric acid etching process could not only provide more active sites for the subsequent grafting modification of epoxy-based silicone oil， but also increase the chemical crosslink density between carbon fibers and the resin.]]> 2022/11/21 0:00:00 MA Shanshan,TIAN Haochen,FEI Jie,LI Hejun,HUANG Qiyue 2true 2022/11/21 0:00:00 KONG Zhiqi,ZHANG Meng,LIU Bei,ZHAO Huifang,SHA Lizheng,GUO Daliang 1true
