Özet
Eco-composites are a natural fiber (NF) reinforced composite. The present paper studied
manufacturing prosthetic sockets with composites that use both natural and synthetic fibers. The
composite materials utilized herein are hybrid ones, i.e., laminating polyurethane resin (80:20),
used as a matrix, and reinforced with natural and synthetic fibers. The natural fibers used were
bamboo and kenaf, and the synthetic ones were carbon fiber and perlon. This composite was used
for fabricating prosthetic sockets. The current study investigated the effects of various fiber types
on the mechanical characteristics of hybrid eco-composites were. The materials were created in
three groups, each with ten layers. The first group consists of four Perlon, two Carbon Fiber, and
four Perlon layers. The second one: 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. By attaching sensors to four different parts of the residual limb, the pressure was measured (Anterior, Posterior, Lateral, 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 analysed using the ANSYS
software to assess the stresses, deformation, and safety factors generated during the movement.
The results showed that, when compared to the other two groups, the third group's yield stress,
ultimate stress, elasticity modules, and fatigue are the best. The patient's gait cycle while using
the prosthesis and walking on the force plate generated data that was examined. The patient in the
first case was worn a conventional prosthetic, while the patient in the second case was worn a
composite prosthetic socket. The results of the two cases revealed that there was no difference in
parameters, especially for the manufactured composite prosthetic socket the differences between
the left and right limbs are less obvious and more acceptable.
