Abstract

ABSTRACT: In this study, Medium Density Fiberboard (MDF) was manufactured from bamboo ( Dendrocalamus strictus Roxb. Nees) fibers and phenol-formaldehyde (PF) resins at different hot-pressing pressures using a novel needle-punching treatment to improve the properties of the panel. One-, two-, three- and four-time needle-punching treatments (1TP, 2TP, 3TP, and 4TP) were used in this work. Laboratory MDF panels were prepared by mixing bamboo fibers with 10% of PF resins. The needle-punching treatments were applied simultaneously on resinated bamboo fibers during the mat formation. The MDF mats were then hot-pressed at 14.0, 17.5, 21.0 kg/cm 2 and at 150 °C for 15 min. Thereafter, the physical and mechanical properties of MDF panels were evaluated as per Indian Standard (IS) specification IS: 12406. It was observed that the combination of novel needle-punching technique and hot-pressing pressure enhanced the physical and mechanical properties of MDF panels. Statistical analysis suggested that a combination of 3TP and 21.0 kg/cm 2 of pressures produced the MDF panel with satisfactory results. The research indicated that a combination of needle-punching treatment and hot-pressing pressure could be an excellent technique to improve the properties of the MDF panel.
