Abstract

Composite boards from kawayan tinik (Bambusa blumeana J. A & J. H Schultes) culms converted into fibers by disk refining in combination with shredded waste plastic bags comprised of thermoplastic material were formed in a two roll mill followed by hot pressing for 5 minutes at 180°C and 4.9 MPs pressure. The proportion of plastic to fiber was varied and borax was added in some of the boards to determine its effect on the board?s flame resistance. Physical tests to determine density, thickness swelling, water adsorption, and flammability as well s mechanical tests to determine modulus of elasticity, modulus of rapture, internal bond, and face screw holding ability were undertaken. The boards were found to have densities that consistently exceeded 1 g/cm³ low thickness swelling and low water adsorption. The mechanical tests revealed that modifications are needed to improve the performance of the boards. Borax had little effect on improving flame resistance. Statistical analysis showed significant influence of fiber to plastic ratio on board density, modulus of elasticity and water adsorption. No significant differences in the other properties were observed. The results suggest that the fabricated bamboo-plastic composite boards possess properties that make them suitable as underlayment flooring material and for other applications where dimensional stability and resistance to moisture adsorption is required.
