Design of prosthetic foot from polymer materials reinforced by carbon fibers

Loss of the lower limb can cause loss of mobility. At all places and at all times, efforts have always been made to make up for such a loss. In this work polymer composite materials had been used to manufacture prosthetic foot. Polymer composite materials PMMA:SR/PUR reinforced by carbon fibers (CF) were prepared as suitable material for prosthetic foot then, tensile characteristics were measured and determined. Numerical work included Finite element method (ANSYS-15) was used to analyze and evaluate deformation, stress and strain characteristics of a new designed prosthetic foot, which was treated as three-dimensional structure composite polymer material. The experimental and theoretical results were improved that polymer composite material can be used for this application.
