    Adhesion and adhesion mechanics
    Average adhesive strength is the most common measured result of adhesional experiments. It appears to be the function of different experimental parameters. Inhomogenеous stress distribution in the surface of adhesive joint is the reason of this phenomenon. This is the problem of adhesive mechanics. This paper briefly describes proposed physical approach to solving the problem and compares theoretical and experimental data.
    Keywords: adhesion, mechanics, adhesive bonding intensity, stress, strength, contact layer.

  • Heat-resistant film adhesive of constructive purposes
    The composition and method of synthesis of an adhesive based on the bisphenol A cyanate ester, polysulfone and epoxy novolac resin were developed. The reaction of a cyanate ester with an epoxy resins was investigated by the method of IR spectroscopy. It was shown that copolymerization of an aryl dicyanate and epoxy oligomer leads to receiving the oxazolidinone structures which promoting increase of the moisture resistance. Received epoxy cyanate film adhesive can be used in conditions of high humidity and a temperature to 200°C. This work was executed within implementation of the complex scientific direction 13.1. «Binding for polymeric and composite materials of structural and special purpose» («The strategic directions of development of materials and technologies of their processing for the period till 2030»)
    Keywords: cyanate ester, epoxy resin, cyclotrimerisation, polycyanurate, curing, film adhesive, IR spectroscopy, shear strength.
