In this paper “Environment influence on the solidity of the adhesive joint” I have dealt with the utilization of the bonding metals and practising experimental laboratory tests of adhesive joints depending on different laboratory environments and anticorrosive protection of the samples.
For this laboratory tests I have chosen a universal adhesive. It is a two-component epoxy adhesive with suitable conditions for bonding metals. The samples were made from steel and were produced by the standard ČSN EN 1465. After the bonding and the cure procedure the samples were exposed in H20 environment for exact intervals (parts of the samples were painted by anticorrosive painting). After the exposition I have examinated the solidity of the adhesive joint in shearing stress on the measuring instrument Zwick 050. The samples were compared with etalon that were exposed to no environment.
Results of the particular measuring were described into the graphs and were recorded the break down maximum force. When the samples were broken down I have taken a photo of it, which is in the appendix.
