Mechanical and Thermal Properties of Banana Fiber Composites for Sustainable Applications

This mini-review highlights the advances in banana fiber-reinforced composites (BFRCs), emphasizing their mechanical, thermal, and hybrid properties. Natural fibers, particularly banana fibers, have emerged as sustainable alternatives to synthetic fibers because of their renewability, biodegradability, and cost effectiveness. The review explores the tensile, flexural, and impact properties of BFRCs, describing the influence of fiber treatments, hybridization strategies, and layering patterns on performance. In addition, it examines the thermal stability and conductivity enhancements achieved through nanofillers and hybrid reinforcements. Applications in the automotive, construction, and packaging industries underscore the industrial relevance of these materials. Challenges such as moisture sensitivity and fiber-matrix adhesion issues are discussed alongside future directions for improved composite development. This review comprehensively discusses the potential of BFRCs as eco-friendly materials for advanced applications.
