Abstract

This study investigates tensile and flexural behaviors of carbon fiber reinforced epoxy (CFRE) composite laminates strengthened in different weights multi walled carbon nanotubes (MWCNT) with/without polyvinyl alcohol (PVA) nanofiber mats. First, PVA nanofiber mats modified with 1, 3, 5 wt% MWCNT were produced by electro spinning. Characterization of 1, 3 and 5 MWCNT reinforced/unreinforced PVA nanofiber mats was achieved via transmission electron microscopy (TEM) and scanning electron microscopy (SEM). Then, the produced nanofiber mats were placed in the middle of eight-layer twill carbon fabrics by hand layup after carbon composites were produced by vacuum infusion. Three flexural tests were performed in accordance with ASTM D 7264/D standard so that flexural strength properties of the composites and flexural modulus of elasticity can be found. After that, tensile test was carried out in accordance with ASTM D 3039 for the composites to have single axis tensile strength and modulus of elasticity nanofibers. The tensile strengths of PVA nanofiber mats and 1 wt% MWCNT/PVA nanofiber mats reinforced CFRE composites increased by 4% and 34%, respectively when compared to the CFRE composite.
