Effect Of Nano Al2O3 Addition On The Mechanical Properties Of GFRP Reinforced By Mwcnts

In the scientific literature, nanocomposite materials are widely studied because they introduce considerable improvements in the properties even at a low nanoparticular content. In the present paper mechanical properties of Al2O3/ GFRP reinforced by MWCNTs were studied. The Al2O3 nanoparticles are mixed with vinyl ester resin using ultrasonic bath sonicator in different weight fractions of 0, 1 and 2% with a constant weight fraction 0.5% of MWCNTs in all composites. E-Glass fiber (chopped strand mat) is used as fiber reinforcement. The effect of Al2O3 nanoparticles addition on the mechanical properties such as hardness, flexural and tensile strength were investigated. It was founded that addition of Al2O3 to (GFRP/0.5 wt% of MWCNTs) improves the mechanical properties of composites.
