Vibration Method for the Prediction of Aging Effect on Properties of Particleboard and Fiberboard

The physical and mechanical properties (density, modulus of elasticity, and modulus of rupture) of standard and humidity-resitant types of particleboard and fiberborad were determined by standardized test and wave propagation velocity, obtained from tne natural frequncy in a nondestructive longitudinal vibration test. Four batches of 66 specimens for each type of panel (particleboard and fiberboard) and for each kind of panel (standard and humidity resistant) were tested under initial conditions and after each one of the three aging cycles defined in European Standard EN 321:2001. Each aging cycle consisted of immersion in water, freezing, and high-temperature drying. The decreasing ration of wave velocity was used to predict the decreasing ratio of properties. There was a strong relationship between both variables, and an exponential regression model is proposed to predict physical and mechanical properties, with a determination coefficient (R2) from 0.93 to 0.98.
