Classificação dos coeficientes de variação para as propriedades de painéis de madeira aglomerada

Abstract

At present, the properties of panels produced with reconstituted wood, especially the agglomerates, have been studied quite well, especially when dealing with their assigned physical-mechanical properties. However, these properties have high coefficient of variation (CV) indexes, starting from some generic classifications. In this sense, the objective of this work was to generate classification intervals in order to determine the accuracy of experiments in this area. In order to do so, we used the CV of the physical-mechanical properties obtained from relevant technical-scientific articles on reconstituted wood panels. Based on the results the following classification was generated: Water absorption: Low = CV ≤ 7.22%; mean = 7.22 54.51%. For swelling in thickness: Low = CV ≤ 9.71%; mean = 9.71 39.12%. For MOE: Low = CV ≤ 8.05%; mean = 8.05 33.85%. For MOR: Low = CV ≤ 9.84%; mean = 9.84 39.45%. In perpendicular traction: Low = CV ≤ 4.70%; mean = 4.70 48.88%.
