Abstract
A finite element study using ANSYS R18.1 was performed to predict the mechanical behavior of multi-walled carbon nanotubes (MWCNTs) filled polyurethane (PU) composites. Using finite element modeling, a tensile specimen model of PU was developed and reinforced with MWCNTs having different angular orientations/inclinations (vertical, 45° inclined and horizontal to axis of loading), within the PU matrix. Finite element analysis (FEA) of MWCNTs reinforced PU composite has revealed that the maximum von-Mises stress is taken up by the MWCNTs filler materials, thereby relieving the most critically loaded sections of the PU matrix. A pure model of PU has been critically stressed within its gauge section for von-Mises stress of 18.8 MPa. Reinforcement of MWCNTs into the same gauge section successfully relieved critically stressed sections of PU by nearly 1.98 times for all the orientations, thereby encouraging the ease of use in manipulating MWCNTs. PU is a weaker material and vulnerable to failure when subjected to heavy external loading. Reinforcement with a lightweight and mechanically strong filler material of MWCNTs has indicated significant stress reduction at critical sections, thereby widening the scope of PU for load-bearing engineering applications. The superior load transfer properties of MWCNTs have been suggested reason for the stress reduction.
