Introduction Modified epoxy materials are fairly often used as coatings, substrates or interlayers. In this case, it is important to have a material with low susceptibility to long-term mechanical effects, including local, and to know the mode of failure. There are various approaches to estimating the service properties of polymer coatings; however, the standard procedures of mechanical testing are inapplicable to such specimens. In this case, one has to resort to alternative test methods. An indirect method for determining the material tensile strength parameter proposed by F. Carneiro, a Brazilian engineer, in 1947 has found wide application in materials science and in industry (construction, mining, etc.) (Rodriguez et al., 1994). The method consists in that material strength is determined from diametral compression 20 The Authors.
