Abstract

Hybrid composites have been concerning in the wide variety of applications especially in the aircraft industry. Therefore, it is fantastic to achieve a hybrid composite with a high mechanical performance. For this purpose, it has been decided to imbed secondary nanoscale reinforcement into matrix of glass/carbon/epoxy composite where amino multi-walled carbon nanotubes and hybridization of amino multi-walled carbon nanotube and Nanoclay (Cloisite 30B) have been utilized. The tensile, flexural and impact properties of hybrid composites have been evaluated and a comparative study between hybrid composite reinforced with amino-MWCNTs and simultaneous amino-MWCNTs and Nanoclay has been conducted. The fractured surfaces of tensile testing and bending testing specimens were characterized with a high precise field emission scanning electron microscopy. The results of the tensile test revealed that incorporation of amino-MWCNTs reduced the ultimate strength of hybrid composite while the elastic modulus of composite with combination of amino-MWCNTs and Nanoclay increased. It was demonstrated that incorporation of nanotubes (MWCNTs) exclusively the same as hybridization of amino-MWCNTs/Nanoclay enhanced the flexural properties of conventional composites with highest increment of 10.5% and 22%, simultaneously. Simultaneous presence of nano-fillers resulted in 50% flexural modulus and strength respectively for hybrid composite reinforced with combination of amino-MWCNTs and Nanoclay. Morphological characterization of composites indicated to strengthen interfacial interaction of fabrics to epoxy when matrix reinforced with nano-fillers especially in combination of both nanotubes and nanoclays.
