ВЛИЯНИЕ ГАЛЛУАЗИТОВЫХ НАНОТРУБОК НА ФИЗИКО-МЕХАНИЧЕСКИЕ СВОЙСТВА ЭПОКСИДНЫХ КОМПОЗИТОВ

Since the second half of the 20th century, many attempts have been made all over the world to create polymer composites with enhanced performance characteristics by modifying them with additives such as rubber, mineral filler, and also organic and inorganic particles [2-3]. To achieve enhanced performance properties of composites, manufacturers introduce combinations of various modifier additives into epoxy matrices, the use of which allows solving most of the problems associated with the operation and durability of polymeric materials. Currently, the most successful fillers of epoxy systems are the most successful carbon nanotubes (CNTs), which are rightly considered ideal additives for polymers because of their high strength and tubular structure [18-20]. In this study, we studied the effect of halloysite nanotubes (HNTs) on the mechanical properties of cured epoxy-based samples. Mechanical tests were carried out according to the methodology of national standard of the Russian Federation GOST R 56800-2015 “Polymer composites. Determination of mechanical tensile properties of unreinforced and reinforced materials” (ASTM D638-10 “Standard test method for tensile properties of plastics”). The following results were obtained: uniaxial tensile strength was improved by + 18.58%, elastic modulus - by + 6.90%, elongation decreased by -15.57% in samples containing 10 wt% halloysite. In this study, halloysite nanotubes have been shown to be effective as an epoxy filler compared to CNTs - halloysite particles are more preferred because of their low cost.
