Wood sawdust and eggshells are very easy to get, wherein the eggshell contains CaCO3, it will be used as a filler in the manufacture of composite boards and polystyrene as a binder (matrix). By varying the ratio of sawdust and eggshell 0:50, 10:40, 20:30, 30:20, 40:10 and 50: 0 (gr), we expect to get a quality composite board. This research analyzes compressive strength, water absorption and density. In this research, the first thing to do is a treatment consisting of diminution, sifting. Then proceed with board making. For the strength of the composite board, a compressive test is performed. From the test it was found that the greatest compressive firmness is owned by the board with a filler ratio of 20:30 which is 94.564 kg / cm2, the highest water absorption value is obtained on the board with a filler ratio of 50: 0 that is 31.517% and the largest density value obtained on the board with a filler ratio of 20: 30 which is 1,231 gr / cm3.

The Impact

This paper introduces a new bamboo wood composite board structure, which board uses little diameter class bamboo as raw material. Bamboos cut into segments and remove part of the bamboo surface from double sides or four sides. Make the bamboo segments have two or four smooth surfaces. Through arrange the bamboo segments reasonably, minimize the impact of differences in bamboo segments straightness to the bamboo wood composite board. And then rolling brush the smooth bamboo segments surfaces with adhesive. Gluing between the bamboo segments from left and right sides and gluing bamboo segments with fiberboard from top and bottom sides. After the hot pressing and cutting edges, the bamboo wood composite board shaping.

Abstract The crosswise gluing of cross-laminated panels made of solid wood can cause problems when exposed to moisture variations. In the present study, the substitution of the spruce middle layer by a wood composite is tested for its influence on moisture-induced stresses and deformations in laboratory tests and numerical simulations. Furthermore, slits in the spruce middle layer were investigated. The hygroscopic warping due to a moisture gradient, stresses caused by moistening and cracks due to drying were studied. The results show larger warping in composite laminates compared to the spruce cross-laminate, which is governed by the modulus of elasticity of the middle layer. The in-plane swelling was found to be larger in composite laminates, while stresses were lower. The drying test discovered that cracks develop in the middle layer of spruce-medium density fiberboard laminates due to shear stresses and tensile stresses in the thickness direction. It was concluded that slits can be applied in the middle layer, as they have no significant influence on moisture-induced stresses but increase the thermal insulation. If the substitution of the spruce layer is required, the application of oriented strand board in the middle layer is recommended.

Composite Board

In this paper, the carbon fiber mechanical properties of wood composite board were discussed. The microscopic structure of the composite material was analyzed based on finite element method. A unit cell model was established, and element stiffness matrix of the model was developed. The model was used to predict the mechanical properties with feasible and accurate affects. The results of experiment showed that after carbon fiber being mixed, the MOE, the MOR and the IB of medium density fiberboard was significantly improved.

Basic Approaches

Deep processing of wood raw materials is the main field of its use. The forecast of timber industry development provides deep chemical processing and start-up of board materials production. In the available forest reserves the share of pulpwood and forestry engineering raw materials is up to 13 per cent. Some measures will contribute to settle the problems of increasing wood raw material complex use and green production of board wood composite materials. They include the improvement of existing technologies and implementation of progressive technologies and systems increasing the volume and quality of board output. One of the main directions will be the maximum possible use of all components of raw materials, when some production wastes are the raw material for the manufacture of new products. This will provide the balance in efficient environmental management. The priority will be given to creation of a relatively closed cycle of wood resources use. Particularly promising in achieving a balance of economic and environmental interests of society will be obtaining of cheap boards capable to be not worse than solid wood with minimum cost of natural resources and preservation of individual properties of each component.
