Characterization of the Properties of the Biocomposite Material 15 mass% HA/PLA

The objective of this study is to investigate the mechanical properties and visco-elastic coefficients of the biocomposite material 15 mass% HA/PLA. The biocomposite material is manufactured using known technology: extrusion-composition followed by injection molding. The general mechanical properties are evaluated experimentally using standard tensile and bending tests using five specimens made according to ASTM standards. The vasco-elastic behavior is investigated using the DMA AR-G2 Rheometer. The paper also investigates the microstructure of the mechanically stressed specimen breaking surface. Following the experimental research, a database is obtained in numerical form, diagrams, and fractographic images. The paper presents conclusions regarding the mechanical and dynamic behavior of the biocomposite material 15 mass% HA/PLA. The general results of the study provide practical guidance on the usefulness of biocomposite material 15 mass% HA/PLA for orthopedic biomedical applications.
