Abstract

Poly(lactic Acid) screws were fabricated using forging process. The process consisted of two-step, which included bar molding by drawing and threading. Molding temperatures were selected as 70 and 100℃. Machine-cut screws were also fabricated for comparison. In order to evaluate mechanical properties, pullout, shear and twists tests were conducted on the specimens. Higher pullout and shear strength were obtained for the screws forged at 70 ℃. Twist strength were almost the same values for screws molded at any conditions. However ductile behavior was observed for screws molded at 70℃. These results suggest that the forging at 70℃ is the best molding process.
