Figure 5:Fractographs of Starch+ Glycerin based ‘green’ Composites-(a): 45% Corn Starch + 25% Bagasse fiber composite shows high rough fracture surface with lot of small size fibers pull-outs (blue arrow) and micro cavities and pulled out fibers (red arrow); (b): Cassava Starch + coir fiber showing the shows the interface with better fiber–matrix adhesion in the composite; c: Castor bean oil cake + 25% banana fiber showing fractured fiber embedded in the matrix; (d): Mango puree + 36% (w/w) CNF (B). [Scale bar = 1 μm]; (e): Maize starch + 10% cellulose nano fibrils of wheat straw showing fiber bundles embedded in the matrix (shown by arrows) without any fiber pull-out or debonding and (f): Coating of starch on the bagasse fiber surface in the composite [21,25,29,32,35].
