DURABILITY OF POLYMERIC COMPOSITE MATERIALS ON THE BASIS OF ANAEROBIC SEALANT AN-111

The paper considers a mechanisms of influence of disperse particles on the strength properties of polymeric composite materials. The authors have determined consistent patterns of impact strength of compositions depending on the durability of a filler and the module of elasticity. The paper presents a technique to study the resistance of polymeric composite material to cyclic loadings. The authors have conducted researches of the influence of carbon nanotubes on the impact strength of polymeric composite materials and their durability at cyclic loads. The also propose a technique and research results of the durability of fixed connections of roller bearings. The analysis of durability tests carried out for 330 hours of continuous bench operation has shown that at the greatest possible radial loading of equal 20 kN the durability of nanocomposition connections of anaerobic sealant AN-111 is up to 60% higher as compared with unfilled sealant AN-111(the destruction of a glue line with a thickness of 0.2 mm was observed in 24 hours for an unfilled sealant and in 39 hours for a polymer composition). The application of this nanocomposition allows to restore fixed connections of roller bearings with a wear degree of up to 0.125 mm.
