Many a time, in order to improve the overall thermomechanical properties of the developed composites, either natural polymers such as cellulose are used as resins in addition to the reinforcing fibers or synthetic polymers are used for polymerization. Some of the unique advantages of these biobased materials are that they offer good biodegradability and biocompatibility. This helps them to find their application in the field of biomedical engineering and also in tissue engineering. When used in the biomedical field, inside the human body, these scaffolds that are engineered must be capable of degrading in a way which is nontoxic to the user. It should also be capable of mimicking the body's own extracellular matrix (ECM) in order to allow the proliferation of human body cells and also to avoid an immune response. The rate of gradation of these scaffolds must take place in a proper way. Hence, it becomes difficult for us to synthesize these biobased polymers alone. Nanoparticles such as hydroxyapatite (HA) could be used for nanoscale hybridization of natural and synthetic materials [18] or carbon nanotubes [19]. The following are the most common fabrication methods used for developing biobased composites.

They are:

1 Solvent Casting and Particulate Leaching (SCPL)

2 Emulsion Freeze Drying

3 Electrospinning

4 Blow Film Extrusion

5 3D printing
