Effect of surface treatment on physico-mechanical properties of bagasse fiber reinforced biocomposites and their applications: a critical review.

In response to rising environmental concerns, research into biodegradable composites as long-term alternatives to synthetic plastics has advanced. This review focuses on important problems associated with bagasse fiber surface treatment, thermoplastic and thermoset resin reinforcement, and the usage of bagasse fiber reinforced composites in various sectors. The surface treatment of the fiber improved its compatibility, allowing the production of thermoplastic matrix-based biocomposites that adhere to green chemistry principles. These composites demonstrated promising mechanical properties, with tensile strength ranging from 4-85 MPa and flexural strength in the range of 26.2-210 MPa. They exhibit moderate hydrophobicity, absorbing 10-25% water after 24 hours, and maintain thermal stability up to 250 °C. Bagasse fiber reinforced composites are feasible for modern engineering applications and other industrial uses because of these qualities. This study highlights fiber surface treatment as a workable, low-impact method for waste valorization in addition to addressing current performance and environmental deficiencies. The review concludes by examining various product uses, present issues, and potential directions for the development of environmentally friendly composite technology.
