Studying
the Tensile and Buckling for PMMA Reinforced by Jute
Fibers for Prosthetic Pylon |
The main
objective of this research is studying the tensile and buckling
of Jute fibers reinforced composite by varying the number of
Jute fibers layers and fibers angle (±45° & 0°/90°). Vacuum
bagging technique was adopted for the preparation of laminated
composite specimens that made from PMMA as matrix and Perlon
layers with different number of Jute fibers layers as
reinforcement materials. Also the finite element method
(ANSYS-15) was used by creating a model of prosthetic pylon and
applied compressive load at heel strike step from gait cycle to
know the critical buckling stress. The results showed that the
best laminated composite specimens have three Jute fibers layers
at (0 º /90 º) fibers orientation relative to applied load.
Where, the critical buckling stress, tensile strength, and
modulus of elasticity were (442MPa, 61MPa, and 3.75GPa)
respectively, while, the percentage elongation was (2.1).
