Original Abstract

The supply of materials on the construction market is very broad, almost inexhaustible, in an effort to satisfy the financial and social requirements of all investors. Steel, aluminium and composites are currently the most commonly used materials in construction applications. The joining of various parts and components is usually ensured by traditional mechanical or welded joints, the efficiency and durability of which has been already proven many times. On the other hand, adhesive joints proved their efficacy too and moreover, they allow the implementation of flexible joints that provide a solution with uniform stress distribution. This article presents the results of the stress/strain behaviour of flexible adhesive joints with steel and composite substrates that are very often brittle; drilling or welding could cause their weakening. High strength 1-K polyurethane and 1-K modified polymer adhesive systems were tested, four in total, in combination with different representatives of the substrate. Joint design similar to butt joint was used, therefore each test sample was composed of two components: 1) EN AW-6060 (AlMgSi) T66 aluminium alloy disc; and 2) the tested substrate: a) COR-TEN® steel, b) aluminium composite panel (Alu-Bond), and c) high-pressure laminate (HPL). Moreover, all test samples were exposed to artificial weathering, as a result the effect of different temperatures (ranging from -20°C up to +70°C) and environments (from 0% up to 100% humidity) on bond strength and failure mode was monitored. The relation between bond failure energy density and bond tensile strength was investigated. For all the test samples a consistent relation was observed, however, the strain energy density that corresponds to the bond failure energy was entirely different for each of the adhesives tested. The dependency of adhesive stiffness on strain energy density was manifested. On the contrary, the effect of different weathering methods was not dominant, only slight deviation were observed in the combination with HPL substrate.
