Increasing the Reliability of Water Transport via the Usage of Modified Epoxy Coatings

Summary/Abstract: In solving the problem of energy and resource conservation in transport, polymer composites are of paramount importance. Polymer composite using makes it possible to significantly improve the mechanical properties of the materials and simultaneously to increase the durability of the parts of transport machines. The authors of this article focus on the substantiation of introducing the modifier 4.4'-methylenebis(2-methoxyaniline) with low concentrations into the epoxy resin. Such materials are characterized by increased mechanical strength and the ability to withstand static, dynamic stresses, as well as impact loads, since the values of the properties are: bending stresses at bending - σ = 51.2 to 54.4 MPa, modulus of elasticity at bending - E = 3.0 to 3.2 GPa, impact toughness is W = 8.8 to 9.0 kJ/m2. The obtained results of experimental studies of the composite materials properties are in good agreement with the results of testing samples by optical microscopy, which indicates their reliability.
