Abstract

Sandwich-like composite mouldings, comprising a polyethylene (HDPE)/hydroxyapatite (HA) composite outer layer and HDPE/Carbon fibres (C fibres) core were produced by the mono-sandwich injection moulding method. The mouldings were mechanically characterized by tensile tests. Bioactivity tests were carried out in a simulated body fluid (SBF) for periods of time up to 30 days. Morphological, structural and chemical characterisation of the formed films was also conducted. The developed composites present interesting values of mechanical properties due to the selective reinforcement strategy adopted and exhibited a strong in-vitro bioactive character.
