Study On The Configuration And Adhesion Process Of Bamboo-Wood Composite Container Flooring

Based on the basic theory of composite, phyllostachys pubescens, woven into curtains, and a sort of poplar, peeled into veneer, those grow widely in southern China, being chosen to be surface and core material, a new composite container flooring was formed via the design of rational structure and the research of hot pressing process. The following conclusions have been derived: 1. At first, the feasibility of manufacturing a sort of composite container flooring by putting bamboo and poplar together was certified according to the properties of two sorts of material and based on previous studies on bamboo-wood composite container flooring. Then, a predict model for the bamboo–wood composite container flooring was derived from the laminated panel rigidity theory in composite structure. 2. It was certified that the bamboo curtain panel manufactured with 6 layers of curtains of 0.8mm thick under the following hot pressing factors: pressure 5 MPa, time 8 minutes, and temperature 140 ℃, is best suit to be the surface material of composite container flooring with such high property values as longitudinal MOE 13558 MPa, transverse MOE 5430 MPa, longitudinal MOR 180 MPa, and transverse MOR 110 MPa because the stronger the surface material, the better the board in accordance with above laminated panel theory of composite. This experiment was accomplished with three controllable variables, i.e. pressure, temperature, and time, and three levels configuration in the same assembling thickness. 3. It was found via the study of relation of mechanical properties of poplar plywood and its compression ration (CR) that the density, MOE, MOR of poplar plywood evenly enhance as its CR increases when CR ranges from 0.54% to 22.64%, but the extent of MOE and MOR enhancement slows when poplar CR is in the range of 22.64% to 28.62%. On the other hand, when a composite panel was made of above bamboo curtain board and poplar plywood, it was found that the MOE and MOR of bamboo-wood composite panel enhance remarkably when poplar CR increases from 0.54% to 18.04%, and when poplar CR keeps on increase, the enhancement of MOE and MOR reduces gradually. 4. In accordance with the predict model derived from laminated panel theory of composite mechanics and the relationship of properties of panel and poplar CR, two structures was designed and hot pressed by adopting two step hot pressing. Finally, an optimized composite container flooring gained with longitudinal and transverse MOR 104 MPa, 43 MPa; MOE 10629 MPa, 36 MPa respectively, and density 0.8 g/cm3, which meets the demand of container flooring standards completely.
