摘要: In this study, composites based on carbon fiber and a modified epoxy resin were obtained. The modification the polymeric matrix was performed by adding functionalized multi-walled nanotubes coated with zinc sulphide particles (MWCNT-ZnS), synthetized hydrothermal synthesis assisted microwave. For comparison, samples containing only (MWCNTf) also tested. influences chemical, structural, mechanical, thermal properties of evaluated. filler characterization, X-ray diffraction, transmission electronic microscopy, Raman spectroscopy used. evaluated thermogravimetric analysis mechanical evaluation laminated made tensile impact tests. results showed that strength Young’s modulus increased presence nanofillers. absorbed energy had higher values for MWCNTf. It verified MWCNTf-ZnS more thermally stable, mainly due to ZnS coating MWCNTf surface.
