Abstract

Biocomposite materials based on collagen matrix could be used for bone defects repair. Hydroxyapatite and β–tricalcium phosphate particles are generally used as filler because they are biodegradable ceramics and offer the composite materials properties similar to that of the bone. Different ratios of bioceramics were used in order to obtain collagen based sponges. A critical role in newly bone tissue formation is played by porosity and pore size of the composite biomaterials. Using different technique (Xray diffraction, FTIR and SEM) we demonstrate the influence of the bioceramic ratio on the porosity, pore size and structural properties of collagen based composite materials. Also, due to their properties, the obtained composites appear to be potential biomaterials for bone tissue engineering..
