Experimental Study on Influence of Multiwalled Carbon Nanotubes on Thermal Behavior of ABS & PETG Hybrid Polymer Composites

Abstract

Polymer composites with enhanced thermal conductivity not only exhibit impressive heat transfer capabilities comparable to metals and ceramics but also preserve the inherent benefits of polymers, including their lightweight nature, ease of processing, and cost-effectiveness. These composites find extensive applications in aerospace, electronics, medical devices, and various other industries. Polymer-based composites incorporating multiwalled carbon nanotubes (MWCNTs) were created, and the impact of different concentrations on the thermal stability of the resulting hybrid composite was examined. This study examines the way of behaving of PETG and ABS materials fabricated through 3D printing and built up with differing measures of carbon fibers (CF) and multiwall carbon nanotubes (MWCNT). The study aims to shed light on the ways in which these materials improve polymer properties, focusing particularly on the beneficial effect of reinforcement on thermal behavior. Additionally, the influence of temperature on the thermal properties of hybrid polymer composites is briefly addressed. These findings underscore the significance of both the content and dispersion state of nanoparticles in shaping the thermal characteristics of such composites.
