Abstract

The invention discloses a cross-layered composite wood bamboo material and a preparation method thereof, the composite wood bamboo material comprises at least two layers of superposed bamboo and woodlaminates and grid composite layers disposed between the plurality of bamboo and wood laminates. The fibers of the adjacent bamboo and wood laminates are arranged at 90-degree; the method is as follows: after the at least two layers of bamboo and wood laminates are superposed, the grid composite layers are arranged between the plurality of bamboo and wood laminates, and the cross-layered compositewood bamboo material can be obtained after gluing and cold-pressing solidifying, The cross-layered composite wood bamboo material has the significant advantages that the cross-layered composite woodbamboo material not only has good mechanical and weathering properties, and strength and rigidity in the longitudinal and transverse directions of parts are enhanced.

Description

technical field [0001] The invention belongs to the field of composite materials, in particular to a cross-laminated composite wood and bamboo material and a preparation method thereof. Background technique [0002] Along with worldwide forest resource reduction, people begin to study the bamboo-wood composite material work that is main raw material with bamboo and artificial forest timber. The composite of wood and bamboo can rationally exert the excellent characteristics of bamboo and wood, and obtain the double effect of saving wood resources and ensuring the strength and appearance quality of the material. Compared with pure bamboo wood-based panels, wood-bamboo composite materials are more designable in structure and performance. From the perspective of bamboo utilization, the former is also more superior than the latter. Therefore, as engineering structural materials, wood and bamboo aggregation materials have broad prospects, and also open up new ways for the industr...
