Abstract

In the present work,‘Nanoclay-Glass Fiber Reinforced EpoxyComposites(NGFRECs)’are produced by handlay-up process with a varying weight percentage of glass fiber and nanoclay.NGFRECs undergo two variety of thermal shock conditions.As prepared composite s and thermal shock conditioned specimens are tested for tensile and flexural strength according to ASTM standards.To optimize the responses variables,‘Design of Experiment(DOE)’based on the full factorial design (33=L27)isused. MINITAB18 software is used for design and analyses. Results revealed that increasing glass fiber weight percentage and nano clay has enhanced the flexural and tensile strength, whereasthermalshockconditionsdeclinedaforesaidstrengths.ThefailuremodeoftheNGFRECas disclosed from SEM images include any of the following combinations,fiber pullout,rupture of the matrix,fiber-matrixde-bonding, delamination, matrixcrazing, initiation and propagation of microcracks
