Abstract
This paper presented the investigation of the effect of adding natural fiber kenaf fiber on the stress and
deformation in below-knee socket prosthetic structures manufactured from composite laminated materials
with various reinforcement fibers. This work included theoretical, experimental and numerical study, in
theoretical part the weight of the patient on the remaining limb was analyzed mathematically using Matlab
2018 a program, the result of the pressure was 165 Kpa. As for experimental part, the artificial socket was
manufactured from the second proposed composite materials with kenaf, testing the ground reaction force
(GRF), as the results showed that the proportion of similarity between the uninjured leg and healthy is
96%. Numerical analysis part using the finite element method was adopted to estimate the Von Mises
stresses and deformation behaviors for the below-knee prosthetic structures through ANSYS 2020 R2, The
simulation using the mechanical properties of the relevant composite materials taken from previous
published and the pressure generated from the mathematical equations was compared with the results
using the pressure readings obtained from the experimental test F-Socket readings of a similar patient
condition as input to the ANSYS program. The results of the composite material using kenaf showed that
the highest value of Von-Mises stress is equal to (34.14 Mpa) for the experimental F-Socket test, while the
value (48.9 MPa) was obtained from theoretical part, as the stress was reduced by the lamination with
kenaf in the experimental F-Socket test (43.23%) and theoretically (10%), to reduces the deformation of
the material and comfort of the patient during movement. Finally, the different between the results was
calculated for the theoretical and experimental F-Socket analyzes were acceptable values.
