Abstract
The tensile properties of poly (l-lactic acid) (PLLA) and polycaprolactone (PCL) composites filled with nanometer calcium carbonate (nano-CaCO3) were measured at room temperature and different tensile rates. With increase of the PCL weight fraction, the tensile elastic modulus, tensile strength and tensile strength at fracture for the PLLA/PCL/nano-CaCO3 composites decreased nonlinearly, and it increased slightly with increasing tensile rate. When the PCL weight fraction was less than 60%, the elongation at break for the composites increased slightly and then it increased sharply. This indicated that PCL was beneficial to improve the tensile fracture toughness of the composites.
