Abstract
Silver nanowire (AgNWs) is a new kind of one-dimensional nanomaterial. AgNWs have been prepared with the polyol reduction method. In this research, the nanocomposites content silver nanowires and graphenes has been studied. The synergic effects of silver nanowires and graphene nanocomposites had been researched for their thermal and electrical properties. The addition of graphene has improved the thermal and electrical properties of nanocomposite. In the same time, the thermal stability of nanocomposites AgNWs and can be enhanced due to the gas impermeability of graphene. A new type of polymer resin, benzoxazine, has mixed with epoxy became co-polymer to enhance the thermal oxidation stability with their batter water and gas impermeability. The AgNWs has been coated on the carbon fibers with dip-coating method. The mechanical properties of carbon fiber reinforced polymers (CFRP) content AgNWs are fail easily, because of the serious delamination of CFRPs. The flexural and torsion tests were decreased obviously. In the torsion fatigue, with the small angle twisting (30°), the fatigue life of CFRP contents AgNWs have barely negative effects, de to the AgNWs may resist the crack propagation. However, with the larger angle twisting (40°, 50°), the fatigue life of CFRP contents AgNWs reduced dramatically with the weakly interfacial interaction between AgNWs, carbon fibers, and epoxy.
