![]() By embedding natural fibers with renewable resource-based biopolymers such as cellulosic plastics polylactides starch plastics polyhydroxyalkanoates (bacterial polyesters) soy-based plastics, the so-called green biocomposites could soon be the future. These biocomposite materials are designed to have a better environmental impact than conventional plastics as well as to promote an improvement in their mechanical properties so that their applications can be expanded. A variety of natural and synthetic biodegradable polymers that can be used as biocomposite matrix are commercially avaiable. Īs conventional plastics are resistant to biodegradation, the concept of using biobased plastics (biodegradable polymers or biopolymers) as reinforced matrices for biocomposites is gaining more and more approval day by day. The type and reinforcement geometry impart strength to the matrix and the resultant composite shows optimized properties such as high specific strength, stiffness and hardness with respect to the specific components. Also, other additives as plasticizers, pigments, heat and light stabilizers are frequently added in order to provide certain properties. The continuous phase are termed matrix and the discontinuous phase can be a reinforcement (reinforcing agent) or filler. Thus, at least two distinct materials that are completely immiscible are combined to form a composite. Composite materials are material systems which consist of one or more discontinuous phases embedded in a continuous phase. ![]()
