Fabrication and Analysis of Wear Properties of Polyetherimide Composite Reinforced with Carbon Fiber

Polyetherimide composite is one of the most non-flexible and lightest composite materials which is difficult to machine by conventional machining process. This material has widespread applications in mechanical engineering, industries, etc. Polyetherimide composite has excellent properties of high-temperature stability, specific stiffness performance, high durability, corrosion resistance, wear resistance, high conductivity and self-lubrication. In the present investigation, 24-layered structured matrix was constructed and properties such as hardness and quality of carbon-fabricated composite structure using dry sliding method have been examined. Further, to testify its applicability in aviation and automobile industry the simulations were illustrated to comment on its mechanical strength. There is a reduction in coefficient of friction by 66.67% noticed at 70 N load, which is associated with surface modifications from frictional heating. Further, to examine and evaluate material’s stress and strain strengths a set of simulations were carried out with a maximum von Mises stress of 2145.4 GPa on ANSYS Workbench 18.1. Finally, it has been concluded that as the layers of the carbon fiber content increase, hardness along with wear resistance of reinforced carbon fiber for polyetherimide composites increases.
