TRIBOLOGICAL AND MECHANICAL BEHAVIOUR OF POLYETHERIMIDE REINFORCED WITH GLASS FIBER & GRAPHITE POWDER
Keywords:Composites, Accumulative diffusion bonding, shear strength, bonding strength
Polyetherimide (ULTEM 1000) in granules form is one of the newest high-performance thermoplastics. Its graphite and short-glass-fiber filled composition was evaluated for mechanical and wear properties. Wear behavior of glass fiber reinforced PEI composites with different percentage of graphite powder is observed on pin on disc apparatus at different loads. It was observed that the adhesive wear is decreased remarkably due to increasing percentage of graphite powder. The wear mechanism was studied with scanning electron microscopy by analyzing the worn and unworn surfaces of the specimen. The mechanical properties were also improved slightly.
