Tribological Characterization of the Natural Fiber‐Reinforced Polyimide Composites

The usage of natural fiber-reinforced polymer composites for tribological applications is growing due to a demand for biodegradable, environmentally friendly composites with superior friction resistance compared to traditional friction-resistant materials such as copper, asbestos, and others. The natural fiber-reinforced polyamide composites have greater capacity to withstand frictional forces and disperse heat. As of late, more researches are centered on biocompatible composite materials because of their eco-compatibility and biodegradability. Despite the fact that synthetic fiber composites are not environmentally friendly, the majority of analysts are interested in natural fiber composites due to their cost and environmental contamination features. As a result, research into the tribological behavior of biodegradable composite materials is required. Natural fibers' properties and the ease with which these composites can be made have tempted researchers to focus on their tribological properties, particularly for a wide range of tribological applications. The purpose of this chapter is to review the tribological behavior of natural fiber-reinforced composites and to look at how friction and wear vary with different load circumstances. This audit examines studies on natural fiber-reinforced composites with special attention to filament types, frameworks, polymers, strand treatment, and test boundaries in order to appreciate their utility for a wide range of applications.
