MECHANICAL PROPERTIES OF TWO EPOXY ADHESIVES WITH DIFFERENT CURING TIME
ResumoAdhesive materials have been widely used in various areas of engineering, especially in the automobile industry, building structures in civil, aerospace and other industries, replacing other conventional methods used in joining metals and other classes of materials. Thus, there is a need to improve knowledge about the behavior of these adhesives, in particular, the mechanical and adhesion properties. This work aims to present a comparative study of some of the mechanical properties of two epoxy adhesive materials with differences between cure time. For this, a comparative study was developed that proved to be quite adequate, evidencing the differences and similarities in the behavior of the materials. In this methodology the performance of metallic plates bonded with these adhesives, as well as the mechanical properties of the adhesive itself, is analyzed. Two types of adhesives were studied, where metal plates were glued and tested in shear strength tests, as well as the adhesives were tested in a tensile test. The results showed that, even if these adhesives showed differences between curing times, method of use and application, these showed similar behavior up to approximately 3.0 kN of load application on shear strength in the adhesion test..
