Abstract

<abstract abstract-type="main" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <sec id="mame201300189-sec-0001" sec-type="section"> <p>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‐<italic>co</italic>‐terephtalate) (PBAT), and their blends were investigated as skin material. Composite core material was made from poly (3‐hydroxybutyrate‐<italic>co</italic>‐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.<inline-graphic xlink:href="ark:/27927/pgg55mvwnrs" content-type="mame201300189-gra-0001" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></p> </sec> </abstract>
