Abstract:
Nowadays, natural composites are more preferable than synthetic fibers because of
their degradability, lightweight, low density, excellent mechanical property, low cost, and
environmentally friendly. In this thesis work, the mechanical properties of bamboo fiber
based composite materials using different fiber orientations, [0°]5, [±15°]5, [±30]5 and
[±45°]5, is estimated with the help of SolidWorks Simulation software. For this study, I
considered axial compressive load applied faraway at three different positions, (350, 275,
0) mm, (350, 275, 275) mm, and (350, 110, 110) mm, for the analysis of the proposed
chair leg design with the specification of 350mm height and 40mm outer diameter and
the volume fraction of 60% fiber and 40% matrix. A total load for these case studies is
1,962N (200kg). The analysis was done on the mechanical properties for each lamina and
laminate, based on different fiber orientations and loading cases.
The analysis results show that the highest stress is appeared at the outermost ply for
every fiber orientation case. Also, the results reveal that [0°]5 is the best orientation angle
for the proposed case study and [±15°]5 orientations angle was founded as the second
choice of fiber orientations from the four orientation cases. Finally, I suggested that to
improve the strength of the cylindrical bamboo fiber based composite material chair leg,
the future works need to be focused on the outermost ply.
