Composites Bamboos can be considered as environmentally friendly furniture material. Thinking to find alternative raw materials of furniture, should be developed steadily. Eye and mind need to be opened, including composites Bamboos as raw material alternative furniture.
Why look for alternative raw materials? Because the timber will be increasingly expensive and scarce. Meanwhile, the needs of home furnishings will always increase with increasing population. Without any alternative raw materials from forest wood for home furnishings or furniture, so fewer needs are met, the more expensive price, and it is not impossible that deforestation will be more and more wild. Full regulation does not work counter deforestation. Nature will be threatened
The findings of Prof. Dr. Bambang Subianto MSc, Head of Innovation Centre LIPI, Serpong, Tangerang, Banten Province, needs to be heard and taken into account. Composites Bamboo is worth for bamboo flooring, home board. Bamboo is as strong as teak wood composite or steel and can last up to 25 years.
What is Composites Bamboo?
Composites Bamboo are processed bamboo. Bamboo split vertically into 2 parts. Then pressurized hot 25kgf per cm2 and 150 degrees centigrade for 30 minutes. Then laminated to the wood beams. Bow building consultant of the Dutch RDA Technologie BV, composites Bamboo proved that it had the strength and durability of wood equivalent to class I and II, as hard as merbau, bengkirai, teak.
Nor intang Setyo H of the Faculty of Engineering Unsoed said bamboo fibers have high tensile strength, 2 times the tensile strength of steel reinforcement. "When the bamboo used as a composite beam can save the use of wood and the cost was cheap," said intang. Bamboo durable because the silica content in the parenchymal tissue to achieve 0.1 to 1.78%.
Bamboo diameter homogeneous effect on the density of the composite. If using bamboo are smaller at the end, "The thickness can be made uniform with the provision of glue as a filler, but the density will be different," said Subiyakto.Bamboo is used at least 4 years old who have optimum strength. Compare with the age of the average tree decades.
In principle all types of bamboo can be made of composites. However, the best results obtained when using homogeneous diameter bamboo from the base to the tip such as bamboo Dendrocalamus giganteus Sembilang aka bamboo and bamboo rope Gigantochloa apus apus. .
Origins The idea of Composites Bamboos
According to Dr. Ir Subiyakto MSc – bamboo researcher at LIPI Biomaterials Research Center – the idea of making composites Bamboo begins visit to China. In a country that he saw the Bamboo Curtain bamboo floor coatings used to replace the terrazzo and ceramic tiles.
That experience continues imagined in his mind. After arriving in the homeland, researchers are interested in trying it. However, "There has been no crusher machines (graders, red) corresponding to the bamboo," said Subiyakto.
Incidentally father of 3 children saw wood shredder at Kyoto University, Japan. He imitated the design. The first engine is complete late 1997. It is driven electric motor-powered 7 horsepower.
The disadvantage, groove grinding wheel was too loose so pelupuh – which leveled parts of bamboo – which produced less smooth. As a result the process of alignment must be repeated up to 7 times. Therefore he makes a more perfect machine in 2000. The third groove inside the wheel presses different density, tenuous at the beginning, rather tight in the middle, and most meetings at the end. The difference plot is to refine and expand on cracks.
More and fine cracks, the better the glue uniformly dispersed so that the composite density and strength. "If the direct use grinding wheels that meeting, need more powerful machines. Also at risk destroying the bamboo, "said Subiyakto. With the new machine was quite a process 3-4 times. To produce a piece of composites Bamboo board measuring 240 cm x 120 cm x 4 cm, need 5-7 bamboo stems along the 6-7 m
