One of the main properties of solid materials are their stiffness. Acoustic vibration non-destructive tests have been successfully used to predict the stiffness, i.e. Young’s modulus or modulus of elasticity (MOE) values of solid wood and wood-based panels. In this work, there was an attempt to evaluate the relationship of dynamic MOE longitudinal and static MOE values, of low-density panels produced from bark particles reinforced with various length glass fibres. The findings of the results and the observed strong coefficients of determination suggest the possibility of the proposed Non-Destructive Test (NDT) method as a prediction tool for the MOE estimation of similarly produced bark-based panels. By means of this non-destructive method can be tested the materials without breaking the material and the results available right after the test.
