| Abstract [eng] |
Dependence of durability of adhesive joints of monolithic black rubber glued applying polyurethane glue with a textile material on temperature, load and surface roughness was investigated in this paper. Master curves were constructed using the temperature-time analogy. Dependence of the coefficients of the WLF equation on grain size of the abrasive material that was used to roughen the surface was determined. A complex master curve was plotted using two analogies in parallel that can be used to forecast the durability of adhesive joints depending on three factors – temperature, load, and abrasive grain size. Analytical expression of this dependence was derived after approximation of the complex master curve with the three-variable function. Fractal dimensions of rubber surface profiles were found, and their relation with the abrasive grain size was determined. A dependence of adhesive joints durability on temperature, load, and fractal dimension was found. |
