Mechanical Characterization of Basalt/HDPE Composite under In-Vitro Condition

The objective of this study was to characterize the mechanical behaviour of basalt/HDPE composite under in-vitro condition. Basalt fiber has been performed as an alternative reinforcement material to reduce the domination of the synthetic fibers such as carbon and E-glass fiber in the medical application. Mechanical testing such as tensile, flexural and impact were performed to determine this composite performance before in-vitro testing conducted. Comparisons have been done towards carbon and E-glass using HDPE as a resin. In-vitro testing of basalt/HDPE was conducted in duration 4 weeks. The results shows the basalt/HDPE has a higher mechanical properties compared to E-glass/HDPE and lower compared to carbon/HDPE. Results of tensile and flexural after in-vitro testing are slightly reduced in 5% by week. Charpy impact test of Basalt/HDPE was performed and also experience a reduction in 7% of strength value. Scanning Electron Microscope (SEM) is used to analyze the surface and texture morphology before and after in-vitro testing. No bio-activity or significant changes have been identified at the Basalt/HDPE composite based on the SEM data. It can be concluded that the basalt/HDPE was combined well as a composite material under in-vitro condition as well can be introduce in medical application.
