The fibrous structure, high lignin content, and abundant low-cost availability of husks make them an excellent reinforcement material for composite applications. Extensive research has focused on developing both partially and fully biodegradable composites using husk fibers in epoxy, polypropylene, polyethylene, and various other resin systems. To enhance composite performance, husks have undergone numerous chemical and physical treatments aimed at improving fiber–matrix adhesion and mechanical properties. Parallel efforts have explored the incorporation of natural and synthetic adhesives to further optimize material behavior. Fully biodegradable composites have also been achieved by combining husk fibers with degradable matrices such as poly(lactic acid), and even binderless composites have been successfully produced. Husk-based composites have been reported to have excellent thermal and noise insulation and mechanical properties.
