Abstract

The effect of the wt.% composition of bio-blends on their physical and mechanical properties is systematically investigated. The examined bio-composites comprise of polycaprolactone (PCL) reinforced by hydroxylapatite (HAP). Compositions, ranging from pure PCL to a 50% (w/w) PCL/HAP, with 10% HAP intervals, were subjected to differential scanning calorimetry (DSC), compression experiments and tribometer friction tests. The DSC investigations revealed high physical compatibility of the 2 ingredients as parameters like glass transition and melting temperature maintained virtually unaffected over the entire composition range. Compressive experiments indicated that the ceramic phase (HAP) is a major determinant of the produced composite mechanical strength while the interaction imposed by the filler material on the polymeric matrix was also evident in terms of wear development.
