Özet
Eco-composites is a natural fiber (NF) reinforced composites that are the focus of numerous scientific and research projects, those composites are studied in the present paper for manufacturing prosthetic sockets where natural and synthetic fibers were used as reinforcement. The composite materials utilized here are hybrid ones made of natural fibers like bamboo and kenaf as well as laminating polyurethane resin and synthetic fibers like carbon fiber and Perlon (80:20). The current study investigated the effects of various fiber types on the mechanical characteristics of hybrid eco-composites. The materials were created in three groups, each one with ten layers. The first group consists of four Perlon layers, two carbon fibers, and four Perlon layers. The second group includes two layers each of Perlon, kenaf, carbon fiber, and Perlon. The third one has two Perlon layers as well as two layers each of bamboo fiber, carbon fiber, and Perlon. The research also includes three different levels of interface pressure measurement between the socket and the limb. The pressure between the socket and the residual limb was measured by placing sensors on four different areas of the residual limb (Anterior, Lateral, Posterior, and Medial). The patient was a male who was 26 years old, weighed 73 kg, was 175 cm in length, and had his right leg amputated. The interface pressure is measured, applied to the socket, and mathematically analyzed using the ANSYS software to assess the stresses, deformation, and safety factors generated during the movement. The results showed, as compared to the other two groups, that the third group's yield stress, ultimate stress, elasticity modules, and fatigue are the best.
