Abstract

A new durable biomedical composite for prosthesis was designed to obtain enhance mechanical and viscoelastic properties, in particular nanohardness and young’s modulus. The nanoindentation technique was employed to investigate nano-scale mechanical properties of unsaturated polyester resin and its advance prosthesis lay-up nanocomposite resin with different amount of exfoliated graphite fillers loading. It has been observed that the young’s modulus of the nanocomposites gradually increase with increasing amount of reinforcement content. With incorporation of 1.0 wt.% exfoliated graphite into polymer matrix, the nanohardness and elastic modulus are improved by about 23% and 37%, respectively. The young’s modulus data obtained by nanoindentation are compared with those obtained by flexural testing. The studies prove that nanoindentation is an effective tool for advance applied biomedical polymer nanocomposites.
