Effect of the mixing on the mechanical and thermal behavior of HDPE/Hydroxyapatite composites

Abstract:

In composite materials is important an adequate dispersion of the filler on the polymer due to the effect exerted on the material's behavior and as a consequence in its biomedical application. For this reason the objective of the present work is to analyze the thermal and tensil properties of HDPE composites with different hydroxyapatite compositions (10-30 wt.%) prepared by two different methods, extrusion and solution in decaline. The results showed that a better dispersion was reached and as a consequence, resistance at break and Young modulus increased for the composites prepared through solution.
