Abstract
The main objective of this work was to evaluate the mechanical properties of the 3M EC-847 adhesive according to temperature variation and cure time. For this was done the comparison of the results with data of the manufacturer regarding the methodology of bonding. In addition, a statistical analysis of the results was performed through variance analysis and Tukey test to obtain the most positive curing processes in the shear strength. The complete factoring planning was used for the execution of the experiments. The experiments were divided into three groups; each group being defined by the cure temperature. Each experiment, i.e. for each temperature and cure time, five replicates were performed. The median time used is recommended by the manufacture and the other two had cure times 20% above and below the reference value provided by the manufacturer. The best responses were given for cures done at 150°C in times of 8, 10 and 12 minutes and at 100°C in the 95 minutes. In addition, it has been proven that the curing process at room temperature does not present good results.
