Abstract
This study explores the effect of adding Multi-Walled Carbon Nanotubes (MWCNTs) to epoxy matrices to meet the need for more robust and lighter composite materials for aerospace applications, focusing on acetone utilization as a solvent to improve nanotube dispersion. The experimental method included ultrasonication for effective MWCNT dispersion in acetone, followed by their incorporation into epoxy resin via filament winding. Comprehensive mechanical testing and morphological characterization were also carried out deploying tensile testing and Scanning Electron Microscopy (SEM). The results demonstrated that integrating MWCNTs significantly enhanced the mechanical properties of the composite material, including ultimate tensile strength, Young’s modulus, and elongation at break. This improvement was especially pronounced at a 1% MWCNT concentration, exhibiting a tensile strength increase of up to 102% compared with pure epoxy. The analysis of fracture surfaces via SEM revealed that homogeneously distributed MWCNTs effectively reduced delamination, enhancing resistance to crack propagation. These findings provide critical insights into fabrication techniques, offering potential advancements in composite manufacturing processes that could significantly improve fuel efficiency and payload capacity in aerospace applications.
