摘要：
The flexural properties of poly-L-lactide (PLLA) and polycaprolactone (PCL) shape memory composites filled with nanometer calcium carbonate (nano-CaCO3) were determined at room temperature. The results showed that with the increase of the nano-CaCO3 weight fraction the flexural moduli and strength of PCL/nano-CaCO3 composites increased roughly linearly and reached a maximum at the filler content of 2%, while the flexural strength of the composites decreased. The flexural moduli and strength of the composites decreased roughly linearly with increasing PLLA/PCL ratio for the PLLA/PCL/nano-CaCO3 composites.
