Properties of Sprut-5M Adhesive-Based Reinforced Coatings

1 Properties of Sprut-5M adhesive-based reinforced coatings 

Let us consider the sections of the tension diagrams that correspond to steel deformation. On section II of the diagram, which corresponds to the steel yield plateau, the polymeric coating takes the whole load gain, which amounts to 7500 N. 

The value of the yield limit and the extent of the yield plateau depend on a number of factors related to the steel structure and the test conditions. In our experiments, the yield plateau ended at deformations e of 1.2%. Under further deformation the steel began to harden (section III of Fig. 3.4). It is evident that at this stage of specimen failure the glass-reinforced plastic coating facilitates the increase of strength. 

Sprut-5M adhesive-based reinforced coatings allow an increase in the strength of the metal, mainly under the conditions in which the load on the specimen exceeds the elastic limit of the steel. 

These are frequently the condtions under which structures operate that are weakened by intensive metal corrosion—pipelines, oil tanks, ships. Sprut-5M adhesive is successfully used for strengthening
