Manufacture of specimens and mechanical properties determination of structural adhesives under static loading condition
Abstract eng: The paper presents the method of manufacturing specimens for testing mechanical properties of structural adhesives during a monotonic tensile test and the method of determining the Poisson ratio. Tests carried out on two examples of structural adhesives: Plexus MA300 and Epidian 53 cured with hardener Z1, differ significantly in viscosity in open time. This requires the use of other methods of manufacturing specimens with a low number of defects and high repeatability. Due to the exothermic crosslinking process, specimens for testing construction adhesives can not have large dimensions. Therefore, it is not possible testing with two extensometers to measure longitudinal and transverse deformations at the same time. The article presents the method of measuring deformations in two load cycles.
