Abstract
Abstract Present investigation focuses on the inquiry of effect of incorporation of multi walled carbon nanotubes (MWCNTs) into plain weave aramid fabric reinforced epoxy (AE) composites on its physical and mechanical properties. The MWCNTs were dispersed into the epoxy system at 0.15%, 0.3% and 0.5% by weight. For homogeneous dispersion and better interfacial adhesion, the filler was subjected to ultra-sonication in the epoxy medium. Uniform impregnation of resin mixture into fiber mat and improved fabrication was ensured by subjecting the stacked laminate with uniform pressure of 1 MPa. The laminate coupons according to ASTM standards were subjected to mechanical tests like hardness, tensile, flexural, and impact. Modification of epoxy matrix with MWCNTs could increase the interfacial adhesion between aramid fiber and epoxy matrix. Obtained results indicated that the addition of 0.3 wt% MWCNTs into the AE composite considerably improved the mechanical properties. Finally, it was concluded that MWCNTs hybrid AE composites will provide alternative constructional materials respect to conventional materials.
