  • In this work, Five varieties of reinforcing materials (fibers and particles) were each laminated separately with PMMA matrix used for manufacturing trans-tibial prosthetic socket and fabricated using vacuum molding technique. The tensile and fatigue properties of Five trans-tibial prosthetic sockets were studied experimentally, theoretically and by using finite element method (Ansys-11). Results showed that the weakest laminate based on mechanical strength (Tensile strength and Fatigue limit) was [PMMA+8Perlon layers]composite and the highest mechanical strength was found in [PMMA+(3Perlon+2(Carbon +Glass)+3Perlon) layers] composite. Results of finite element method and theoretical calculation also indicate that the [PMMA+(3Perlon+2(Carbon +Glass)+3Perlon) layers] composite has the highest safety factor and the lowest values of both (deformation and failure index) making that composite the best candidate to give better fatigue characteristics of trans-tibial prosthetic socket.
