Experimental Analysis of Tensile and Flexural Characteristics of GFRP Laminates Infused with Multi-Walled Carbon Nanotube (MWCNT) Nano-fillers
J. Environ. Nanotechnol., Volume 13, No 4 (2024) pp. 185-190
Abstract
This research investigates the influence of varying concentrations (0%, 1%, and 2%) of multi-walled carbon nanotube (MWCNT) nano-fillers on stretching and bending characteristics of a composite material (glass fiber-reinforced polymer (GFRP) laminates). The results show a significant enhancement in strength with increased nanomaterial content, specifically, the strength under tension increased from 114.51 MPa to 155.53 MPa, while the stress under bending increased from 152.269 MPa to 187.26 MPa. These improvements in mechanical properties are attributed to several strengthening mechanisms, including grain refinement, dislocation pinning, and interface strengthening between the nanomaterial and the matrix. The addition of nanomaterial enhances the material stiffness, as reflected by the increased flexural modulus. A slight reduction in ductility was observed, indicated by a decrease in strain at failure. The uniform dispersion of the nanomaterial within the matrix was crucial in achieving these enhanced properties. The observations indicate potential applications in aviation and automotive sectors, where superior strength and rigidity are essential. Further investigations should examine different nanomaterials and evaluate the material under diverse loading scenarios to enhance its performance.
