This thesis focused on utilization of nanomaterial for fabrication of socket
prosthetics. Prosthetic socket is one of the important parts as it involved
interfacing or connecting link between the stump and prosthetic components. In
addition to the functionality of the socket, it also has to involve the patient’s
satisfaction due to the force distribution and pressure on the stump. Recently,
several materials utilized in socket prosthesis yet they did not cover all that
existing problems. This investigation suggests using Nano-SiO2 particles and
MWCNTs in reinforced woven fiberglass for fabricating socket prosthetic transtibial. Tensile, flexural and shear tests have been conducted on composites with
three different weight percentage of hybrid nanoparticles (Multi-Walled- Carbon
Nano Tubes (MWCNTs) and Silica Nano Particles(SNPs)) namely
(0.1wt%MWCNT - 1wt%SNPs), (0.2wt%MWCNTs - 2wt%SNPs) and
(0.5wt%MWCNTs - 5wt%SNPs). The optimum mechanical properties were
achieved by using the specific weight percentage of hybrid nanomaterials was
(0.1wt%MWCNT - 1wt%SNPs) and it was observed that tensile, flexural and
shear strength improved up to 34%, 20% and 14.14% compared to neat glassepoxy composites. Likewise, the tensile, flexural and shear moduli increased by
27.6%, 31% and 26%, respectively. The Abaqus software has been used for
analyzing the socket trans-tibial’s stress distribution and deformation. Tsai-Wu
and Hashin failure criterion have been employed to check the reliability of the
structure. The results have shown that woven glass fabric with (0.1wt%MWCNT
- 1wt%SNPs) of hybrid nanomaterials has the potential to replace the existing
glass fabric-based polymer composites. It is a great initiative to fabricate a
prosthetic socket which biodegradable, environmental, lightweight, comfortable
and psychosocially acceptable.
