Abstract
ABSTRACT The use of polyimide-reinforced composite materials in the design and fabrication of components for mechanical and tribological operation systems remains a research focus. As such, the present study investigated the effect of electrical corrosion resistance (ECR) glass on the mechanical and tribological properties of hybrid-polyimide composites using spark plasma sintering (SPS) method. The hardness and elastic modulus of the thermoplastic polyimide reinforced with TiO2 and ECR particles was investigated in this study with a nanoindentation tester under applied load of 200 mN. While the friction and wear behavior of the composites was ascertained with pin-on-disc tester under 10 N at 150 rpm with a stainless steel counterpart at room temperature. The results showed that the ECR glass addition remarkably improved the hardness and elastic modulus of the hybrid composites. Incorporation of the 10 wt% ECR glass effectively reduced the friction coefficient and wear rate by 55.5% and 92.2%, respectively, corroborating the potential of these ECR-TiO2-PI composites for applications requiring a low friction coefficient and wear rate with high mechanical properties.
