Abstract
ABSTRACT In the current study, the enhancement of the mechanical and tribological behavior of polyimide (PI) composites with varying TiO2 nanoparticles fabricated with spark plasma sintering (SPS) technique was examined. The morphology, mechanical, and tribology of the produced nanocomposites were characterized using scanning electron microscope (SEM), nanoindenter, and tribometer analyzer. The SEM result shows that the TiO2 were diffused uniformly in the polymer matrix. The hardness and modulus of the PI increased with the incorporation of the TiO2 nanoparticles by 314.1% and 76.4%, respectively. Furthermore, the friction coefficient and wear resistance of the nanocomposites was remarkably improved with the TiO2 incorporation.
