This work is studying the simulation and testing prosthetic socket made from new arrangement of composite materials. two composite arrangements. The first arrangement is consisting of ten layers of carbon fiber while the second group is made of ten Perlon layers. This research prosthetic is for a 20-year-old female patient with a height of 155 cm and a reported weight of 75 kg. The results of the mechanical properties explained (Ϭult) and (Ϭy) for group 2 was 145 MPa and 137 MPa, while for group 1 was 285 MPa and 280 MPa. The limit of group (2) fatigue was 145 MPa and group (1) was 78 MPa. The interface pressure applied on the stump was measured using F-Socket for four regions of the stump; this data is (Anterior 495kPa, Lateral 427kPa, Posterior 384kPa and Medial 351kPa). The fatigue safety factor was found using the Ansys14.5 software, it was found that the fatigue safety factor of the prosthetic limb socket which made of carbon fiber is (1.2) which could be considered sufficient in terms of design requirements. On the other hand, the fatigue safety factor of the prosthetic limb which is made of Perlon fibers is (0.096) where it considered as a failure.
