The objective of the research was to determine the rigidity modulus with dynamic torsion tests in solid wood and multi-material samples of Fagus crenata. Twenty-four solid wood specimens were prepared for torsion tests. Once the tests were done, 12 multimaterial specimens were made with this same material, made up of two solid wood plates that cover a steel mesh, joined with a two-component polyurethane adhesive. A second series of torsion tests was carried out with these specimens. Normality and verification tests and analysis of variance were performed. The average density of the multimaterial increases 7.2 % in relation to that of solid wood. The modulus of rigidity of the multimaterial increases 13.7 % compared to that of solid wood and the coefficient of variation decreases 71.1 % compared to that of solid wood. The multimaterial exhibits a technological improvement due to the increase and stability of its stiffness when subjected to elastic angular deformations. In this way, the mechanical characterization of the multimaterial shows its potential for innovation in non-traditional applications of solid wood in residential construction.References
