Abstract
The present experimental work investigates the influence of E-glass fiber hybridization on the tensile and bending characteristics of sisal fiber reinforced epoxy polymeric composite laminates. The bi-directional sisal fiber was treated with an alkali (NaOH) and laminated specimens were fabricated by using hand-layup method. Furthermore, the present investigation extends to explore the effect of introducing Carbon nanotube (CNT) and MXene (Ti3C2Tx) nanoparticles on the elastic behavior of glass-sisal fiber hybrid composites. The nano-fillers were dispersed and blended with the neat epoxy by using sonication method. The multiscale structure of the MXene dispersed hybrid plates were examined by using scanning electron microscopy. It was found that the tensile strength of the sisal/glass fibers laminate got enhanced by 42% upon reinforcing MXene. In addition, it was observed that the bending strength and bending modulus of sisal/glass fibers laminate was increased by 34% and 30% respectively, when using MXene nanoparticles were reinforced into the matrix. Based on the experimental results, it was inferred that the surface characteristics of the MXene and CNT nanoparticles play a significant role in improving the tensile and flexural properties of the sisal/fiberglass reinforced hybrid laminate.
