摘要：

Concentration dependences of the strength of filled epoxy resin-steel wire (diameter 150 mu m) adhesive joints are studied. Nanostructural powders of aluminum oxide with cylindrical particles (diameter 4-6 mu m and length 30-40 mu m) are used as fillers. The structure of cured compositions is studied by X-ray diffraction techniques and it is established that nanostructural Al2O3 fibers are porous. The effect of the scale factor is studied. It is shown that the breaking force increases nonlinearly and the strength of the adhesive joint decreases with an increase in the bonding area. It is established that the dependences of adhesive strength on concentration are described by curves with maxima. This makes it possible to recommend highly dispersed fillers as a method for the control of interfacial strength.
