The present study focuses on fabrication and mechanical characterization of glass fiber reinforced polymers (GFRPs) filled with low specific carbon nanotube (CNT) contents. The epoxy resins were altered with 0.1%, 0.2%, 0.3% and 0.4% MWCNTs by weight to investigate the effects of CNTs on mechanical properties of GFRPs. Samples of GFRP reinforced with 0.3% MWCNTs had higher tensile (242.22 MPa) and flexural strength (332.53 MPa) as compared to neat GFRPs. Moreover, the hardness values agree with the tensile and flexural test results. The experimental results also reveal that MWCNTs plays a significant role in the enhancement of mechanical properties such as tensile strength, failure strain, and hardness. The morphology of the nanocomposites and fiber–matrix interfacial effects are perceived through scanning electron microscope (SEM).
