Study on the effect of veneer on flexural creep behavior of medium density fiberboard

In this study, effect of veneer on flexural creep behavior of medium density fiberboard (MDF) was investigated. MDF panels were prepared from Pars Neopan industries with 760 kgm-3 density, layered and then laminated with natural and melamine veneers. Their creep behavior was compared to MDF unlaminated as control treatment. For evaluating maximum bending load in static flexural test, samples were cut from panels according to ASTM D 1037 with dimensions of 370×50×16 mm. Then, the flexural creep tests at 20% and 40% of the maximum bending load was applied to the sample prepared. Results showed that levels of stress are effective on all creep parameters, but showed less effect on relative creep. Also, creep parameters of layered MDF were indicated less than laminated and unlaminated MDF.
