  Abstract

The interfacial adhesion property between aramid and rubber is a very important factor when aramid is applied as a reinforcing material for automotive heat-resistant hoses. This study examined the improvement of interfacial adhesion between aramid and rubber by applying plasma and a coupling agent to m-aramid. The SEM, AFM, and XPS characteristics were examined based on the plasma treatment conditions. The plasmatreated aramid was then treated with the coupling agent to analyze the interfacial adhesion with silicon, fluorine, and hybrid rubber. The plasma treatment resulted in an increase in the surface roughness of the aramid, and the mechanical properties of the aramid fabric decreased because the surface of the aramid was fibrillated. Moreover, the interfacial adhesion between aramid and rubber increased by 16.2% with the use of the coupling agent and plasma treatment.
