The objective of this study was to verify the efficiency of nondestructive evaluation of wood panels mechanical properties by stress wave timer method in medium density particle board (MDP) from pine. Were evaluated industrial MDP panels from eucalypts (5) and pine (5), both from two national companies, and five panels from sugarcane bagasse imported from China. Stress wave timer method was used for nondestructive evaluation. The modulus of elasticity (MOEd) obtained by stress wave timer method was confronted with MOE and flexural strength (MOR) to bending tests from conventional assays. Measures in length and width directions were performed in each panel. Nondestructive method was effective only for sugar cane bagasse panels, so it can be used to predict MOE and MOR for this type of panel.Downloads
