AI Article Synopsis
- Several studies have focused on the material properties of clay/polymer nanocomposites, but few have explored their tribological characteristics, which relate to wear and friction.
- This research specifically examined how different concentrations of montmorillonite (MMT) affect the wear behavior of MMT/epoxy nanocomposites through wear tests and SEM analysis.
- The findings indicated that higher MMT concentrations led to lower friction coefficients and reduced wear rates, suggesting that MMT acts both as a reinforcement and a lubricant in these nanocomposites.
Article Abstract
Numerous studies have investigated the material properties of clay/polymer nanocomposites, such as their fracture toughness, elastic modulus, and hardness. However, only a few researchers have studied the tribological properties of clay/polymer nanocomposites. This study investigated the effect of the montmorillonite (MMT) concentration on the tribological behavior of MMT/epoxy nanocomposites. Wear tests were performed on MMT/epoxy nanocomposites with four different clay concentration levels to characterize the improvement in wear behavior due to the MMT concentration. In order to examine the tribological mechanism depending on the clay concentration level, SEM analysis was performed on the worn surfaces after the wear tests. The results showed that the friction coefficient of an MMT/epoxy nanocomposite with a low MMT concentration was larger than that of a nanocomposite with a high MMT concentration. It is believed that the phenomena occur due to the action of MMT as a reinforcement and lubricant material and reduce the wear rate with increasing MMT concentration.
