Research Of The Wood-bamboo Composite Scrimber

The wood-bamboo composite scrimber are put forward as a newly materials on the basis of scriber and bamboo scriber. It can be showed from the result of the test and the theoretical analyses that the producing and utilizing of the wood-bamboo composite scrimber is feasible and have a expansive market foreground. The wood-bamboo composite scrimber contain the advantage of both scriber which is prior in toughness and machining such as smoothly tenon, making hole, nailing, holding tightly and of bamboo scriber which is pretty well in the performance of physics mechanics including high longitudinal strength .stable in dimension, uniform quality, easily controlling according to requirement in length and density. The wood-bamboo composite scrimber have small radius log and branchwood as raw material, so it can be regarded as a effective way of appeasing the problem of wood lack and enlarge the using path of poplar and bamboo.Analyzing these characteristics of the machining mechanism of the wood-bamboo composite scrimber, high strength of bamboo, loose and soft poplar, better of the poplar bundle rolled than bamboo's and good gluing capability. On the condition of fixed temperature, pressure, adhesive condition (the volume of gluing, the type of gluing), by the way of orthogonal design and regress analyses, adjusting the ratio and the constitute of mixed poplar and bamboo, analyzing the relationship between several mechanics performance such as MOE in the chord direction, MOE in the thickness, MOR, strike tenacity and .mixed factor. The number of the tested result increase accordingly with the enlargement of the ratio of bamboo and poplar in weigh, there are nearly relationship of parabola between strike tenacity and the ratio of mixture. The consititute of mixture don't affect the MOE in the chord direction and do the MOE in the thickness, MOR, toughness tenacity.The wood-bamboo composite scrimber is a newly composite material. Referring to the theory of composite material, the paper analyzed the processing mechanisms of simple model and worked out the model equation of the MOE in the tangential direction , the MOE in the thickness direction, MOR , strike tenacity Laying the foundation for the further research about the inner rule of the wood-bamboo composite scrimber...
