A comprehensive overview on tribo-mechanical characteristics of hybrid plant fiber–based biocomposites

Abstract Plant fiber is one of the sorts of environmentally friendly resources that have been replenished over several years by nature and human invention. For the past few years, application of plant fibers as reinforcements into polymer matrixes has gained considerable interest due to their biodegradable nature. Introducing just one type of reinforcing element does not result in composites with remarkable physical and tribo-mechanical characteristics. Lately, significant research and innovation have been observed on hybrid plant fiber–based biocomposites (HPFBCs) in structural and automotive industries. One of the crucial topics that must be reviewed is the tribo-mechanical performances of these composites. Hence, the present review article aims to provide the friction and wear behaviors and mechanical properties of different HPFBCs under different operational conditions. Based on the understanding of tribo-mechanical aspects of HPFBCs, some prospects have also been suggested that need to be addressed and resolved in the future. This review article is anticipated to provide readers and researchers with valuable insights into the significance of tribo-mechanical performances in the assessment of HPFBCs for specific applications.
