The use of non-destructive testing methods on glued laminated wood to obtain data
Resumo
Glued laminated wood is a mechanically processed wood product that requires strict quality control. Non-destructive evaluation can be employed on an industrial scale to improve the quality control process, allowing greater uniformity of raw materials and their by-products. The quality in the manufacture and the structural performance of elements in MLC can be guaranteed by the performance of tests, which have the function of characterizing the physical and mechanical properties of the parts. This work aims to present the main non-destructive methods used by glued laminated wood (MLC) to obtain data. The study presents the visual classification and non-destructive methods used for structural classification, including static flexion, machine stress rating (MSR), impulse excitation method, stress wave, and ultrasound. It is concluded that the choice of the method to be used in the mechanical characterization should be based on the knowledge of the advantages and disadvantages of each one, in line with the definition of the one that best suits the needs, the technique, and the cost of acquisition and maintenance.
