title = "Study on the relationship between the degree of crystallinity and the ultrasonic velocity for poly(lactic acid) (PLA) parts",
abstract = "The relationship between the degree of crystallinity and the ultrasonic velocity was analyzed in this study for injection molded poly(lactic acid) (PLA) parts undergoing an annealing process. An annealing process was first employed to produce PLA parts with different degrees of crystallinity. Next, a novel ultrasonic water immersion method was presented for calculating the ultrasonic velocities of these annealed PLA parts. Then, the ultrasonic velocity results were plotted with the crystallization results from differential scanning calorimeter (DSC) measurements for analysis. Experimental results show that the inverse effective ultrasonic velocity versus the degree of crystallinity over the whole crystallinity range for three different annealing temperatures show good linearity, with a correlation coefficient of around 99%. The linear relationship observed in this study might provide a novel method for investigating the degree of crystallinity of semi-crystalline polymers in practical production.",
