Abstract:
Taghizadeh Manzari, M. (MehrdadThe main goals of this project are studding the effect of carbon nanotube on the properties of PA6/PA66 matrix and miscibility of PA6/PA66 blend. So PA6/PA66/CNT nanocomposites were compounded by melt mixing method and samples were prepared by injection molding. Due to study miscibility of PA6 and PA66, we used DMTA test and found that PA6 and PA66 are miscible because of existing one pick on DMTA graph. Also DSC test results confirmed that PA6 and PA66 are miscible. Moreover, according to DMTA results, modulus will be rose by increasing CNT content. Mechanical test showed same results in this case. Adding 1%CNT to matrix caused 10% improvement in modulus and tensile strength but elongation at break is deducted. Rheology test showed that by increasing CNT to matrix, complex viscosity was increased because of favorable contraction between CNT & matrix. Finally we studied the effect of PA66 grade on the properties of PA66/CNT nanocomposite and found that the molecular weight of PA66 is the most effective factor on properties of mentioned nanocomposite
