Potential of the magnesium powder as filler for biomedical composites

The intensive production of various biomedical composites made from different biomaterials showed a huge volume of information on properties of composite materials for appropriate research field. The matrix of composite materials is very important but the reinforcement materials known as fillers play an important role for the final properties of biomedical composites like mechanical properties or biodegradability. In the last years, many research groups proved that the modification of ceramics or polymeric matrix by adding magnesium powder will conduct to the biomedical composites that will enhance bioactivity and mechanical properties. The aim of this paper was to study the effect of adding magnesium powder as filler in collagen-based composites for biomedical applications. By freeze-drying technology we obtained some collagen-based composite materials reinforced with Mg powder that have shown good homogeneity, good integration of the reinforcement material and superior mechanical properties.
