Biopolymers refer to the type of polymers created by living organisms. Biopolymer composites are biodegradable composites that are manufactured by reinforcing natural fibers derived from plant and animal sources with natural or synthetic biopolymers. Natural fiber in discontinuous phase is added to the biopolymer matrix in continuous phase to improve the tensile strength and stiffness of the manufactured composite. The goal of making this type of composite is to create a product with strong mechanical and durability properties, which are provided through natural fiber and biopolymers. Natural fiber-reinforced biopolymer composites are quickly developing as potential alternative to synthetic-based materials in food packaging, sporting goods, automotive, aerospace, biomedical, furniture, and electronic industries. This book aims to shed light on the processing, properties, and applications of biopolymer composites. It consists of contributions made by international experts. This book, with its detailed analyses and data, will prove immensely beneficial to professionals and students involved in the study and application of biopolymers at various levels.
