Summary

In recent years, thermoplastic composites reinforced with biofibers have received considerable attention of scientists and technologists for various applications, as these composites have several advantages over traditional material-reinforced composites. Biofibers have been widely used as reinforcing materials because they are strong, lightweight, abundant, renewable, nonabrasive, combustible, biodegradable, nonhazardous, and inexpensive. In order to develop composites with better mechanical properties and environmental performance, it becomes necessary to improve the interface between thermoplastics and biofibers. Various chemical treatments such as graft copolymerization of functional monomers onto biofibers and coating of biofibers with bacterial nanocellulose are the best methods to attain these improvements. In this chapter, we report on the various thermoplastic composites reinforced with different biofibers. Special emphasis is given to the composite boards and use of graft copolymers and bacterial cellulose-coated biofibers as reinforcing materials in the synthesis of thermoplastic composites. Applications of these composites in various fields are also discussed in this chapter.
