Flexural strength and thermal properties of carbon black nanoparticle reinforced epoxy composites obtained from waste tires

Abstract

In this study, both mechanical and thermal properties of epoxy@carbon black nanocomposite (EP@CB-NC) produced by adding 0.3, 0.6, and 1% by weight carbon black nanoparticle obtained from waste automobile tires to epoxy were investigated. The chemical and structural composition of EP@CB-NC was characterized by Fourier transform infrared spectroscopy (FTIR) in scanning electron microscopy (SEM). In addition, simultaneous thermo-gravimetric analysis (TGA), differential scanning calorimetry (DSC) experiments, and thermal conductivity measurements were performed to determine the thermal stability of the prepared EP@CB-NC. Increasing the strength of modified epoxy composites by means of nanoparticles obtained with waste may pave the way for obtaining new materials with clean environment and superior properties. The mechanical and thermal properties were improved by adding carbon black to the bare samples.
