Abstract
Epoxy nanocomposites based on a polymeric matrix DER330 + IMTHPA and 5 different nanofillers, i.e., silica of various sizes, aluminum nitride, aluminum oxide nanoparticles and nanofibers, were prepared. The weight content of nanoadditives in the matrix ranges from 0 to 4%. Dependences of mechanical properties of epoxy composites on the nature and concentration of the filler are investigated in a three-point bending test. The morphology of the fracture surface is studied. The complex analysis of the influence of nanoadditives makes it possible to reveal the optimal fillers and concentrations, allowing us to achieve a significant increase in elastic and strength characteristics of epoxy composites. It has been demonstrated that the introduction of A-380 silica nanoparticles into the matrix increases fracture stress by 30%. Composites with aluminum nitride nanoparticles show the highest mechanical values on the strength of all investigated parameters: growth in the elastic modulus is 12% upon an increase in fracture stress by 7%. The addition of aluminum oxide nanoparticles and nanofibers in the range of investigated concentration does not lead to significant changes in the mechanical characteristics of the composite.
