A novel concept of developing green composites with improved performance using co-injection molding technique has been established. Poly (butylene succinate) (PBS), poly (butylene adipate- co-terephtalate) (PBAT), and their blends were investigated as skin material. Composite core material was made from poly (3-hydroxybutyrate- co-hydroxyvalerate) (PHBV) and miscanthus. Co-injected samples with good surface finish were achieved at a skin/core volume ratio of 40/60 and mold temperature of 45 °C. Notched impact strength of 140 J/m, four times higher than that of neat core material and unnotched impact strength of almost 400 J/m with modulus of more than 1 GPa was achieved for the co-injection molded green composites. Good adhesion at the skin/core interface was observed under scanning electron microscopy. [ABSTRACT FROM AUTHOR]
