The goal of this research was to determine the physical (water absorption and thickness swelling) and mechanical (modulus of rupture, internal bond strength) properties of the experimental bamboo mat overlaid particleboard (MOPB) from the planer wastage of Borak (Bambusa balcooa} bamboo in which Mitinga (Bambusa tulda} bamboo was used as mat covering. All the bamboos were 50-60 feet tall and 3-4 years old. Before manufacturing of composite boards, bamboo mats were treated with an aqueous solution of 10% borax-boric acid (w/v) maintaining borax to boric acid ratio of 1:1 to extend their service life. Urea-formaldehyde glue was used for manufacturing the MOPBs as a resin binder. Five single-layer bamboo MOPBs measuring 500 mm x 500 nun x 12 mm were prepared using a laboratory hot press machine with a target density of 750 kg/m3. The results demonstrate tliat the MOPBs made from bamboo planer wastage with a density of 750 kg/m3 have a significant modulus of rupture (MOR) and internal bond (IB) strength value. The values of modulus of rupture of the MOPBs fulfilled both the Indian (IS 3087: 2005) and ANSI (A208.1-1999) standards, whereas internal bond strength values exceeded the Indian (IS 3087: 2005), ANSI (A208.1-1999) and British (BS 5669-2: 1989) standards specifications.


An experiment was conducted to find out the strength properties and dimmsfonal
stability of particleboard using waste wood and planer shavings Collected from Bangladesh
Forest Industries Development Corporaholt (Bl-1 DC). Waste WOod were converted in in chips.
Particleboards were fabricated at fhe different ratios of wood chips and planer shaving such as
100:0, 75:25, 50:50, 25:75, and 0:100, Results show (hat particleboards made from 100% planer
shavings have good static bending properties : 143 kg/cm2) and excellent tensile strength
(13 kg/cuv). Both the values satisfy the Indian and British standard. Tilt1 percentage of
thickness swelling and water absorption were measured a tier 2 and 24 hours soaking in water,
lowest thickness swelling and water absorption were found in the board made of 100% planer
shavings. Particleboa ids made from 75% and 50% planer shavings also satisfy the Indian
standard. It is concluded that planer shavings from different wood based industries can he
used for making conventional partiilebuard of high strength properties.
