Abstract
The struggle in osteosynthesis continues with the
search for more biocompatible materials to replace metallic
scaffolds. Poly(L-lactic) acid (PLLA), a biopolymer, was
processed via melt-blending technique by blending chitosan and
Ti-6Al-2Sn-2Mo-2Cr-0.25Si powders with it in varying
compositions at 290 oC. The microhardness values, compressive
moduli and fracture toughness of the reinforced PLLA improved
significantly while the resulting composites were found to be less
tough than the unreinforced PLLA. Compressive moduli
obtained were much lower than the modulus of cortical bone.
They were, however, mechanically compatible with the properties
of cancellous bone.
