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. The basic of this research new polymer blend self-cure PMMA/SR which can be used in manufacturing the prosthetic foot with a reasonable cost and satisfying mechanical properties accepted. Improvement tensile strength of this polymer blends for this application, one of the simple improve tensile strength of PMMA/SR polymer blend reinforcement by carbon fiber CF. Polymer blends (PMMA:SR) 90:10; 80:20; 70:30; 60:40; 50:50 were prepared reinforcements each one by carbon fibers from 5-15% (CF), then tensile strength test was carried out for prepared specimens, and effect of reinforcement by carbon fibers on tensile strength of polymer blends were determined as one improvement for prosthetic foot material.
