Biocomposites with ceramic fillers and polymer matrix are becoming attractive materials for bone tissue replacements. Nanoindentation has been used to locally characterize the surface mechanical properties of the hydroxyapatite/pOly-L-lactide (HAp/PLLA) biocomposite. Additionally, differences in the mechanical properties of HAP phase were successfully characterized as a function of surface morphology by using a highresolution modulus mapping technique. HAP granules consist of agglomerates of grainy clusters. Mechanical properties of ceramic grains and PLLA are in fair agreement with literature data. High-resolution methods were able to measure the properties of boundary phases between grains and the pore regions between particles in the agglomerate. After short-time immersion in distilled water, material surface showed a large decrease in storage modulus.
