Thermoplastic Composites Based on Polylactide and Calcium Phosphates

Abstract

Thermoplastic polymer composites have been obtained by stretching a polylactide (PLA) melt containing 1–10% amorphized hydroxyapatite (HA). The physicochemical properties of the obtained composites have been studied by XRD, thermal analysis, and microscopy. It is shown that PLA/HA composites are well extruded through nozzles with a diameter of 0.4 mm, retain their shape during 3D printing by the FDM method, and can be used to create three-dimensional porous biomaterials.
