Influence of Carbon Nanotubes on the Mechanical Properties and Morphology of the Thermoplastic Polymer Matrix of the Polyamide 6

Abstract

This paper examines mechanical properties of composites with thermoplastic polymer matrix and carbon nanotubes. Polyamide 6 was used as a basic matrix, to which nanoparticles in the form of nanotubes were added in a described proportion to the weight. Granulate was prepared by cold granulation in the worm extruder. Dried granulate was injected into the Arburg injection molding machine. Mechanical properties were evaluated by tensile and hardness test. These results were then compared with results achieved by polyamide 6 to which no fillers were added. Discussion analyses what is the influence of nanotubes fillers on crystallinity degree of the polymer matrix of polyamide 6. Conclusion evaluates and compares influence of presence of fillers on the mechanical properties of polypropylene matrix.
