Abstract

Due to the widespread use of polyamides in various industries and the need to achieve high resistance to surface scratches and optimum surface roughness, in this paper, surface roughness and surface scratch resistance of polyamide 6 reinforced with nanoparticles of calcium carbonate and maleated polyamide as compatibilizer based nanocomposites specimens have been investigated. For this purpose, components of nanocomposite specimens, with the different weight of nanoparticles of calcium carbonate, by twin coil extruder mixture and specimens by the method of injection molding were prepared. To perform the hardness scratch test, the nano-coupled hardness device was used in the atomic force microscope, which has a nanoscale test instrument equipped. In order to study the roughness and surface scratch resistance of the specimens, the effect of three variables, vertical force of the scratch, the weight of the reinforcing phase and the compatibilizer have been investigated. The results show that the addition of calcium nano carbonate particles from one to three parts per hundred resin, increases the roughness value by about two times, and also reduces the surface roughness by about a 40 percent reduction in the weight of a compatibilizer.
