Fracture and Failure of Starch-based Composites

Although a large number of studies have already been published on biodegradable polymers and particularly on starch-based materials, most of them have not been specifically focused on their mechanical performance and their fracture behavior is usually disregarded. In order to extend the applications of this type of polymer and their blends and composites, a full understanding of their performance is required. Their ultimate performance properties, such as their fracture properties, should be deeply analyzed and the different toughening mechanisms operative in these materials and responsible for this behavior should be identified. The fracture behavior of these materials affects their resistance during processing, handling and transport, determining the extent to which biopolymers can replace synthetic polymers in many applications. In this chapter, recent results on the fracture and failure of different starch-based composites, including starch reinforced with natural fibers, carbon nanotubes or nanoclays, are discussed. A summary of these results and future trends on this issue are also presented.
