The compressive and tensile properties of PLLA/PBSL polymer blends (90/10, 80/20, 70/30) were measured using a universal testing machine and split Hopkinson bar methods. The yield stress of static and dynamic compressive tests for the polymer blends decreased gradually with increasing PBSL. When PLLA/PBSL=100/0, 90/10 and 80/20, a wave-like shape such as Mackerel pattern were observed on the fracture surfaces of specimens after the static tensile tests. The fracture surfaces after the dynamic tensile tests were flat.
