“…It can be seen that the pure PES is a typically ductile material with the yield point (see the inset). Nonetheless, the SCF reinforced PES composites show the linear dependence of the applied load on displacement, which is an evidence of brittle rupture [36]. Both the slope of the loadedisplacement curves and the maximum applied load of the composites increase as the GO loading increases.…”

“…However, it is not evident that this mechanism would lead to the enhanced properties of thermoset—in this case, nanoparticles could hinder network formation during curing and work as defects worsening properties of the resulting materials. And in fact, contradictory data could be found in the literature on the properties of nanofilled epoxy matrices, considering, for example, behavior of glass transition temperature of nanocomposites , and so on.…”

Rheological and mechanical properties of nanofilled epoxy resin were studied, including adhesion to aramid fibers and strength of impregnated aramid strands. Light scattering and rheological measurements data imply that nanodiamonds (NDs) and multiwall carbon nanotubes form stable nanosized agglomerates in epoxy resin, whereas for epoxy‐organomodified montmorillonite systems, individual clay platelets orientation might be present. Also, according to the rheology of these systems, formation of the networks of epoxy molecules adsorbed on the NDs particle surface is suggested. Increase in the viscosity of the epoxy oligomers due to the nanoparticles incorporation results in the worsening of the impregnation of the aramid fibers by these formulations. However, enhanced adhesion properties could be obtained when using nanofillers, with a maximum at 1–2 wt% of nanofillers. A 25–35% growth of the pull‐out adhesion strength is also achieved. Increased cohesive strength and decreased residual stresses are supposed to be the reasons of adhesion strength decrease according to the literature. Adhesion strength increase was accompanied by a 10% enhancement of the strength of impregnated aramid strands. Moreover, a notable effect—up to a fourfold increase—was observed for the impact toughness of epoxy‐nanofillers samples. POLYM. COMPOS., 39:E2167–E2174, 2018. © 2017 Society of Plastics Engineers

The physicomechanical properties and thermal stability of epoxy nanocomposites with TiO2 (anatase – 75%, rutile – 25%) nanoparticles were studied. The TiO2/epoxy polymer (TiO2/EP) nanocomposite films were obtained by curing a pre-sonicated mixture of diane-epoxy resin ED-20, 4,4 '- diaminodiphenylmethane and TiO2 nanoparticles using stepwise technique: 90 °С for 3 hours, then 160 °С for 3 hours. Tensile tests were carried out according to American Society for Testing and Materials ASTM D882-10. The average size of TiO2 nanoparticles and microstructure of the obtained nanocomposites were studied by scanning electron microscopy. It was found that addition of the TiO2 nanoparticles at a concentration above 3 wt.% leads to a decrease in tensile strength at break, apparently due to secondary aggregation processes of nanoparticles. During curing, the average diameter of TiO2 nanoparticles increases from 40 nm to 60 nm. An increase in the elastic modulus, a slight increase in the glass transition temperature, and a decrease in the elongation at break of epoxy nanocomposites at a concentration of TiO2 nanoparticles > 1 wt.% indicate an increase in the rigidity of the epoxy matrix. The nanocomposites obtained were shown to be stable at concentrations of TiO2 nanoparticles up to 5 wt.% and up to 300 °С in vacuum.
