Natural Fiber‐Reinforced, Natural Resin‐Based Biocomposites: Fabrication, Properties, and Sustainable Applications

Natural fiber‐reinforced, natural resin (NFR‐NR)–based biocomposites are a sustainable set of materials developed to offset the ecological and environmental consequences resulting from the use of man‐made composites. The biocomposites are reinforced with the vegetable fibers such as jute, flax, hemp, kenaf, and so on with biodegradable polymeric matrices such as polylactic acid (PLA), starch‐based plastics, soy protein resins, and lignin‐based thermosets. Due to their renewability, low density, biodegradability, and favorable mechanical properties, these materials are gaining significance for use in car parts, construction panels, packaging, and domestic goods. Distinct from the existing literature, the contribution of this review is that there is a systematic linking of processing techniques with properties in fully bio‐based materials in order to provide an application‐oriented overview. Environmental benefits, economic viability, and commercialization aspects are also addressed. Finally, key research gaps and directions for future development are presented to facilitate broader adoption of these green materials.
