Carbon nanofiber reinforced thermoplastic elastomer based on polypropylene/polybutadiene blend: theoretical modeling of Young’s modulus of the nanocomposites with respect to the orientation and agglomeration of carbon nanofiber

Abstract The effect of the addition of carbon nanofibers in a thermoplastic elastomer based on a polypropylene/polybutadiene blend prepared by melt blending process was investigated. CNFs that were tested by transmission electron microscopy demonstrate uniform dispersion of CNFs in the PP matrix. With an increase in filler content up to 3 wt%, Tensile strength and Young u2019s modulus of the PP/BR blend rises with a rise of filler content to 3 wt%. The introduction of CNF in the PP/BR blend has improved the complex viscosity, storage modulus, and loss modulus in the low-frequency zone, according to a dynamic rheological analysis.

Long term hydrothermal effect on the mechanical and thermo-mechanical properties of carbon nanofiber doped epoxy composites

Abstract The effect of water absorption on carbon nanofibre doped epoxy composites' mechanical and thermomechanical behavior was investigated. After removing traveling specimens from a water-beaker, all the composite specimens survived saturation for a long time of six months, but composite change of composites was monitored regularly. Compared to their unsexed specimens, the results revealed a general decline in flexural modulus and tenacity, hardness, storage modulus, and glass transition temperature for seawater exposed specimens due to absorption of seawater.

Microstructure and mechanical properties of aluminium matrix boron carbide and carbon nanofiber reinforced hybrid composites

In this research, an aluminium matrix boron carbide and carbon nanofiber reinforced hybrid composite was developed by powder metallurgy technique and their microstructure and mechanical properties were investigated. The reinforcing elements were found to be remarkably distributed in the aluminium matrix, according to the microstructure analysis. As the CNF number of the samples increased, their hardness values increased, but their TRS values decreased. The wear resistance increased with the increased amount of CNF, according to the wear test findings. The most suitable sample was found to be Al-7%B4C-1%CNF, when the hardness was determined together with TRS and wear test findings.
