Physical and Mechanical properties of MDF board from Bamboo (Dendrocalamus strictus) using Needle Punching Technique


Author(s): Kapil Sihag, Anil Negi, Pawan Kumar Poonia and DP Khali

Abstract: Medium density fibre board has unique properties like uniform, dense, smooth, and free of knots and grain patterns, it may be an excellent substitute for solid wood in many applications. MDF boards are prepared using different ligno-cellulosic materials. Bamboo is being utilized in handicrafts, flooring, doors, fences, housing roofs, and rafters. In the present study fibres from bamboo was used for manufactured of board. The aim of the present study was to find out the effect of needle punch technique on the physical and mechanical properties of MDF boards i.e. density, moisture content, water absorption, general swelling, surface absorption, modulus of rupture, tensile strength perpendicular to grain (internal bond strength) and screw withdrawal strength. Needle punch technique was used on resin blended bamboo fibres during the mat formation for reorientation of fibres for increasing the tensile strength perpendicular to grain (Internal bond strength) of the board. The needle punched MDF Boards were prepared using 6, 8 and 10% phenol formaldehyde resin at three different pressures i.e. 14, 17.5 and 21kg/cm2 respectively for 15 minutes hot pressing at 1500C temperature. Physical and mechanical properties of MDF boards were evaluated as per IS specification 12406:2003. Results indicated that suitable medium density fibre boards made from bamboo (Dendrocalamus strictus) can be prepared using three time needle punching the 8% resin treated bamboo fibres during the mat formation and pressed at 21kg/cm2 specific pressure and with 10% resin content at 17.5 and 21kg/cm2 specific pressures which meet most of the requirements as per Indian Standard specification IS: 12406:2003. Some of the properties i.e. water absorption and general swelling of board were found higher than the required value of Indian Standard specification (IS: 12406) which can be controlled by suitable treatment of fibres.
