Fabrication of a Polymeric Composite Reinforced with Carbon Fibers and CuO Particles for Prosthetic Applications

Abstract

In this research, the mechanical properties (tensile strength, bending resistance, impact resistance) of samples composed of unsaturated polyester resin reinforced with carbon fibers in the form of layers, using four layers, and copper oxide at a rate of (1%, 2%, 3%, 4%) were studied. Both separately. It is used in the manufacture of prosthetic limbs. The results showed that carbon fiber reinforcement improved all mechanical properties. Where as that the tensile strength improved and reached (10.14), while the bending resistance value was (25.34), and the shock resistance also improved by a value of (1.46). However, when reinforced with copper oxide, it failed and also that the tensile strength value decreased to (4.76), and the bending resistance value also decreased to (7.47), but the impact resistance improved and its value reached (0.72).
