Predicting time to failure in bending of wood particleboards under cyclic humidity conditions
Time to failure tests under constant load (30, 40, 50 and 60 % stress levels) were conducted on four different 19 mm thick particleboards with three layers. Two of them were uncoated (UF and MUF bonded) and the rest were melamine (80 g/m2) and veneer (Mukally) overlaid. Tests were carried out in cyclic humidity conditions (30 % - 90 %), at 20º C, 7 days at each condition. Time to failure was recorded, fitting mathematical models to predict time to failure. Melamine coating reduces predicting errors and increases time to failure.
