The Effect of Type of Overlay on Flexural Properties of Medium Density Fiberboard and Particleboard

In this study the effect of type of overlay on the flexural properties of particleboard (Pb) and medium density fiberboard (MDF) was investigated. For this purpose, Pb and MDF panels with density of 660 and 760 Kg/m3 respectively were supplied by Pars Neopan mill. Then panels were overlaid with beech veneer and melamine laminate and were compared with unlaminated panels. Samples were prepared from the panels by 16×50×370mm dimensions according to ASTM D 1037 while they were equally and longitudinally cut. Static bending tests were performed. The results showed that flexural properties in MDF were better than Pb panels. Type of overlay and direction of panels influenced flexural properties. Furthermore, the results indicated that the veneered panels and parallel direction in panels showed higher bending resistance.
