Stress-Strain Characteristics of Polyester Composites with Singlewall, Multiwall and Functionalized Carbon Nanotubes

Abstract:

Performance evaluation of the polyester composites with added carbon nanotubes is presented herein, based on the results of compressive tests. Composites were obtained from polyester resin mixed with three types of carbon nanotubes: singlewall, multiwall and functionalized. The contents of carbon nanotubes were 0.1, 0.15 and 0.2 wt%. Cylindrical specimens with a diameter of 6 mm and a height of 9 mm were designed and prepared in conformity with the standards. Compressive tests were performed according to ISO 604, at the speeds of 1, 5, 10, 25 and 50 mm/min. Morfological study of the samples was carried out using SEM analysis. Dispersive X-ray spectrum in energy, associated with SEM micrograph, enabled to notice the elements existing in the composite. Stress-strain characteristics of polyester composite were determined through the compressive tests. The results revealed improved mechanical behavior of polyester composite, for test speed under 10 mm/min.
