Abstract Aramid fibers and ultra‐high molecular weight polyethylene (UHMWPE) lack active surface functional groups, the is smooth, limiting their practical application in textile composite materials. In this study, zinc oxide nanorods were used to grow on aramid surfaces, oxygen plasma followed by treatment with a silane coupling agent was modify UHMWPE fibers. The effects of modification morphology composition, mechanical properties composites investigated. response interlayer hybrid...
To improve the chemical and physical surface features of aramid fibers bonding quality at interface, carbon nanotubes, dopamine silane coupling reagent KH560 were used to modify fibers. The fiber was characterized by FTIR, XPS, SEM AFM. single-fiber specific strength, roughness, wettability interfacial shear strength modified quantified. Finally, uniaxial tensile behaviour textile composite laminate with tested. experimental results show that: after grafting as a second modification step,...
Abstract Three‐dimensional (3D) braided composites have good integrity and high stability, but aramid fiber (AF) has an inert surface poor interfacial bonding with resin, which affects the mechanical properties of 3D limits their development. This paper used catechol/pyrogallol polyamine (CA/PGPA) to modify AF. The effects different mass fraction ratios CA/PGPA reaction temperatures on AF were investigated. results showed that after modification, oxygen‐containing groups increased, roughness...
