Paper Title:
Tribological and Thermal Properties of Hybrid Kevlar/PTFE Fabric Composite Filled with Nano-TiO2
  Abstract

The hybrid Kevlar/PTFE(polytetrafluroethylene) fabric composites filled with different nano-Tio2 content of matrix resin were fabricated. To determine the tribological properties, the filled and unfilled composites sliding against 45 steel were performed on MM-200 friction and wear tester. Scanning electron microscopy(SEM) was utilized to examine the morphology of worn surface. Differential scanning calorimetry (DSC) analysis was also performed to study the thermal properties of the composites. The results show that the addition of nano-Tio2 improve the wear resistance and decrease the friction coefficient. The friction coefficient become unconstant during test with the increase of nano-Tio2 in the resin matrix, and the optimum fraction of nano-Tio2 in the resin is 1wt%. The SEM observations indicat that microcutting and plastic deformation are the main wear mechanisms. DSC analysis that there is no significant change in the melting points, and that there has been minimum chemical interaction between the resin matrix and nano-Tio2.
