Study On A New Bamboo Wood Particles/ Fibers Composite Board

Wood-based panels industry is a estate which depends mostly on the resources.With the rapid development of wood-based panels in our country and reduction of forestry resources which could be utilized, therefore, how to develop the wood-based panels with saving resources become the vital important problems which our wood-based panels will be up against. A great amount of researches have been done on the saving resources and substitution and so on, such as bamboo and wood composite, the utilizations of resource processing remainders and so on, and many new wood-based panels products have been worked out, which allayed problems that resource which are hard up and improved the structures of wood-based panels.However, there are also some disadvantages, such as low utilization of raw materials and high processing energy, in addition, if the utilization of raw materials is improved, at the same time, the mechanics intensities of products were relatively decreased, which limited the applying ranges of them.My research is based on the research of raw materials (the useless bamboo and wood) and its' processing and compositing modes.Cut the useless bamboo into little particles, constitute a composite mat having reasonable structure with wood-fiber, and it is resembled, hot-pressing through the workable design theory of composite materials, and a new bamboo and wood composite plywood is made.In this article, Cut the useless bamboo into little particles, constitute a composite mat having reasonable structure with wood-fiber, then is hot pressed to composite board. At last we have got the best processing.Base on the first experiment, coMPared with the hot-pressing, we got the best hot-pressing processing.Through checking mechanics intensities and estimating the resource utilization, the results are showed in the follows:(1) it's mechanics intensities achieved or surpassed the national norms for construction template; (2) Experiment results show MOR and MOE of the board reach 32.5 MPa and 3041 MPa, and the 2hTS is 1.7%.The IB is high to 1.45 MPa.So, the board is a kind of new and good-performance Bamboo/wood Composite Board.(3) The assay on costs and benefits showed that the research and development for this product will be meeting with great economical benefits, society benefits and ecological benefits, and have wide applying foreground.
