“…3, and tensile modulus results of these specimens (after drying), as presented previously [11], while Fig. 7 shows the relationship between apparent crosslink density as calculated using Equation (4). A trendline shows that the log of the tensile modulus and saturation swelling or apparent crosslink density of these specimens follow linear behaviour on these axes.…”

a b s t r a c tThe effect of ageing in a sweet oil environment on the tensile properties, apparent crosslink density, CO 2 diffusion and Shore hardness of a typical carbon black reinforced hydrogenated nitrile butadiene rubber (HNBR) is presented. Different ageing conditions yielded materials with different properties, attributed to varying degrees of apparent crosslinking. These results showed that, with increasing apparent crosslink density, tensile stiffness and hardness increased, while CO 2 diffusivity and saturation swelling in chloroform decreased. The relationships between these properties suggests that geometry independent tests (such as solvent swelling) may be performed on parts retrieved from service in order to predict properties (such as tensile stiffness or gas diffusion) which cannot normally be measured on retrieved parts due to geometrical constraints.

“…The most common way to overcome this difficulty is to replace the inorganic Na + cations on the clay surface with the desired organic cations, particularly alkyammonium ions. When these surface-treated clays are introduced into the host polymer matrix, two morphology types form: intercalated or delaminated/ exfoliated nanocomposite structures [110][111][112][113][114]. Epoxy/clay nanocomposites with low clay concentrations exhibit markedly improved mechanical strength, thermal stability, permeability, and flammability compared to pristine epoxy matrices and traditional micro/macro composites.…”

In this study, the effect of adding wood ash (oak tree) on the mechanical properties (tensile, abrasion, tearing, elongation %, etc.) of NR/SBR-type elastomer materials was investigated. Five different compounds were prepared by adding 16 %, 32 %, 48 % and 64 % wood ash to the filler and additive materials in the general composition (G). The mechanical test results and production costs of the new compounds composed were compared between themselves and with the G compound. The fracture surfaces of the compounds as well as the shape and morphological distribution of the fillers in the rubber matrix were examined using a Scanning Electron Microscope (SEM). As a result of the experimental studies, it was found that the new compounds composed had an increased tensile and tearing strength, abrasion amounts, bending capability, unit elongation amounts and densities in comparison to the G compound. A decrease was observed in the hardness values and material costs (production cost) of the compounds. Keywords: compounds, mechanical properties, wood ash Avtorji opisujejo raziskavo vpliva dodatka lesnega pepela (hrasta) na mehanske lastnosti (natezne lastnosti, abrazija, trganje, raztezek v %, itd.) elastomerov tipa NR/SBR. Pripravili so pet razli~nih vrst zmesi z dodatkom (16, 32, 48 in 64) w/% lesnega pepela, ki so ga uporabili kot polnilni in dodajni material k osnovni sestavi (G; angl.: General). Rezultate mehanskih preizkusov in stro{ke izdelave novih zmesi so primerjali med seboj in z zmesjo osnovne sestave G. Prelomne povr{ine zmesi, kakor tudi morfolo{ko porazdelitev polnila v matrici iz gume so opazovali in analizirali s pomo~jo vrsti~nega elektronskega mikroskopa (SEM). Na osnovi analize eksperimentalnih rezultatov avtorji ugotavljajo, da imajo izdelane nove zmesi povi{ano natezno in stri`no trdnost, ve~jo odpornost proti abraziji in sposobnost upogibanja ter enovit raztezek v primerjavi z gumo osnovne sestave G. Ugotavljajo tudi, da se je zmanj{ala trdota zmesi ter da so se zni`ali stro{ki njihove izdelave. Klju~ne besede: gumijaste zmesi, mehanske lastnosti, lesni pepel
