A comprehensive review of mechanical and tribological behavior of bio-polymer composites

In the present study, the mechanical and tribological behaviors of bio-polymer composite materials are reviewed. Focusing on the critical findings of research studies in this field, this study explores diverse features, such as biodegradability, renewability, low density, non-abrasiveness, and suitability for a broad range of applications. Insights are provided into the effects of various factors (e.g., load, sliding speed, and temperature) on friction and wear performance. The contributions of fiber and filler modifications to improved mechanical attributes are also highlighted. This study emphasizes the use of natural fiber-reinforced bio-polymer composites, which are environmentally friendly and cost-effective alternatives to synthetic fiber-reinforced plastics. This study underscores the need for further research to understand property–structure relationships to optimize composite properties, which will open new possibilities for boosting the adoption of bio-polymer composites in diverse applications.
