Studying the metal-polymeric compounds adhesive strength at separation

The experimental method was introduced to establish the influence of structural and technological factors on strength of the metal-polymer materials obtained by gluing. St5ps steel, T-11-GVS-9 fiberglass, VAK-A and Sprut-Plus adhesives were used in manufacture of the experimental samples. Surface roughness, adhesive layer thickness, polymerization time and operation temperature were selected as factors influencing the strength. Minimum normal stress was determined, at which the polymer material destruction started. The UTS-110M machine was used in testing. Experiments were conducted at the adhesion layer thickness of 0.5...2.5 mm, temperature of 20...200°C, polymerization period of 0.5...96 hours and surface roughness of 40, 100, 200, 320 and 400 mcm. Analysis of the experimental data showed that the separation stress was increasing with an increase in the surface roughness. The adhesive layer growing thickness by 5 times led to a decrease in strength by 1.35...1.64 times. The highest adhesive strength corresponded to the polymer layer thickness of 0.5...1.5 mm. It was established that the metal-polymer material strength decreased with an increase in the test temperature by 1.54 times. An increase in the internal stresses was observed in the adhesive during the curing period (from 10 to 24 hours). With the increasing polymerization period, internal stresses practically were not increasing, but were stabilizing.
