Co-influence of nanofiller content and 3D printing parameters on mechanical properties of thermoplastic Polyurethane (TPU)/halloysite nanotube (HNT) nanocomposites
Thermoplastic polyurethane (TPU) belongs to a polyurethane family that possesses an elongation much higher than 300%, despite having low mechanical strength, which can be overcome by incorporating clay-based halloysite nanotubes (HNTs) as additives to manufacture TPU/HNT nanocomposites.

| Summary: | Thermoplastic polyurethane (TPU) belongs to a polyurethane family that possesses an
elongation much higher than 300%, despite having low mechanical strength, which can be overcome
by incorporating clay-based halloysite nanotubes (HNTs) as additives to manufacture TPU/HNT
nanocomposites. This paper focuses on the co-influence of HNT content and 3D printing parameters
on the mechanical properties of 3D printed TPU/HNT nanocomposites in terms of tensile properties,
hardness, and abrasion resistance via fused deposition modelling (FDM). The optimum factor-level
combination for different responses was determined with the aid of robust statistical Taguchi design of
experiments (DoEs). Material characterisation was also carried out to evaluate the surface morphology,
nanofiller dispersion, chemical structure, thermal stability, and phase behaviour corresponding to the
DoE results obtained. It is evidently shown that HNT level and infill density play a significant role in
impacting mechanical properties of 3D-printed TPU/HNT nanocomposites. |
