“…Nowadays, research efforts are centred in developing composites by combining natural fillers with biodegradable resins [ 10 ]. Thus, some researches on poly(lactic acid) (PLA) [ 11 , 12 , 13 , 14 , 15 , 16 ], polyhydroxybutyrate (PHB) [ 17 , 18 , 19 , 20 ], starch-based polymer (TPS) [ 21 , 22 , 23 , 24 , 25 ], polybutylene succinate (PBS) [ 26 , 27 , 28 , 29 , 30 ] or polycaprolactone (PCL) [ 31 ] with different natural fillers/fibres have been reported. In general, it was observed that tensile and flexural modulus increased, but the impact strength and elongation at break decreased.…”
