Impact modified PLA-hydroxyapatite composites – Thermo-mechanical properties

Synergistic composites from poly(lactic acid) (PLA) and hydroxyapatite (HA) hold great potential for load bearing applications. In this study, PLA-HA composites were produced through extrusion, and test specimens were subsequently prepared through injection molding. Impact properties of the composit...
