芳纶纤维/NFC复合纸基材料的界面及强度性能研究
Study on interfacial bonding and strength properties of aramid Fiber/NFC paper based compsite
摘要
Abstract
The interfacial bond strength between aramid fiber and matrix is inferior because of the surface inertness of aramid fiber in aramid paper sheet.Nanofiber cellulose (NFC) has been widely studied in reinforcing composite due to its excellent mechanical performance.In this paper,aramid fiber was modified by phosphoric acid solution in order to increase its surface activity and roughness.The aramid fiber/NFC paper composites was prepared by adding different ratios of NFC and the properties of aramid fiber/NFC paper based composite were investigated.The results showed that the paper tensile index,tear index,interlayer bond strength increased by 1.99,1.5 and 1.66 times,respectively.In addition,TEA was also improved by an increment of 99.7％ with 20％ NFC.It can be found that enhanced mechanical properties of aramid fiber/NFC paper were derived from the strong hydrogen bonding interaction between aramid fiber and NFC by the fourier transform infrared spectroscopy (FTIR).The scanning electron microscopy(SEM) showed that NFC thin film structure just like the "spider web" or "silk" could become the pivotal bonding bridge and filling agent between chopped and fibrid,which could improve interficail adhesion strength of paper sheet greatly.关键词
