| Abstract | ||
| The purpose of this study was to investigate the possibility of producing of medium density fiberboard (MDF) panel from recycled wood fiber from old corrugated container (OCC) to reduce tree cutting and using of wood timber in this industry. Furthermore, the effects of the fiber source and the process variables like resin content and press time and their interactions on the mechanical properties of MDF panels were studied. The results showed that the panels made by wet process from recycled fiber were better than panels made from fiber mixture and virgin fiber in the mechanical properties for Modulus of rupture (MOR), Modulus of elasticity (MOE) and Internal bond (IB). The panels made with resin content 10% were better than panels made with other levels of resin contents for each of MOR, MOE and IB. The panels made by pressing 30 minute were better than all other press periods for each of MOR, MOE. The results of the interaction of fiber source ,resin content , and pressing time showed the superiority of the panels made from recycled fiber with 10% resin content and pressing time 20 and 30 minute for each of MOR and MOE over the rest of panels , whereas the IB was the best in the panels of the recycled fiber with different resin content and various pressing time. The panels with the above mechanical properties had passed the standard requirements for interior application. | ||
