Process Technology and Mechanical Properties of Polylactic Acid Ply Yarns and 316L Stainless Steel Braids

Year: 2011

Type: article

Abstract: Biodegradable polymer has been widely used in surgical suture, dressing, artificial bone and other bone-related applications. However, when compared with the human cortical bone, the pure polymer obviously did not have enough strength. The present study aimed to give preliminary insights from a pilot study of designing a scaffold of polylactic acid ply yarns composited with stainless steel (SS) braids. To evaluate the fabrication processes and alkali effects on the individual materials, the different heating temperature and alkali treating time and alkali concentration were applied to clarify the changes in mechanical strength. The experimental results showed that the strength was not significant declined with alkali and heating treatments. The retained mechanical strength was kept at 100-120 MPa and ultimately led to bone-like mechanical properties.
