Problems solved by technology

However, the tensile strength of laminated veneer lumber is not high, and many domestic laminated veneer lumber manufacturers can only produce non-structural poplar veneer veneer lumber as packaging materials, which affects the scope of use of poplar veneer veneer lumber

Embodiment Construction

[0027] The present invention will be further described below in conjunction with accompanying drawing:

[0028] Such as figure 1 As shown, the present invention is that carbon fiber cloth and poplar wood rotary slices can be formed by laying up method, and processed and manufactured by cold pressing forming technology, and poplar wood rotary slices 1 and carbon fiber cloth 2 are laminated and glued together. Through their combination, greatly improved The mechanical properties of poplar materials. The thickness of the poplar rotary slice 1 is less than 2mm, and the poplar rotary slice 1 and the carbon fiber cloth 2 are bonded by epoxy resin.

[0029] Carbon fiber cloth is used to reinforce LVL. During production, the LVL sheet is first produced according to the LVL production process, and then sawn into LVL sheets of corresponding length and width according to the size of the structural member, and then The thickness problem is solved by laminating the laminated veneer lumbe...

Abstract

The invention discloses a carbon fiber fabric reinforced poplar laminated veneer lumber structural element and a machining method thereof. The structural element is characterized in that the structural element is prepared by alternately laminating and bonding poplar rotary slices (1) and carbon fiber fabric (2), and the structural element fully exerts the advantages of carbon fiber fabric and Italian poplar laminated veneer lumber, greatly improves the mechanical property of an Italian poplar material and the added value and the technological content of poplar production, and greatly broadens the application of field of the Italian poplar through the control of the process flow. Moreover, the structural element can avoid the problems of common anchor failure, peeling breakage and the like when the carbon fiber fabric is adhered outside and exerts the strength of the carbon fiber fabric more fully, so that the structural element can be manufactured into a large-scale lumber structural element and solves the problem that the large-scale lumber structural element cannot be produced currently.

Description

technical field [0001] The invention relates to a component combining carbon fiber cloth and poplar veneer. Background technique [0002] At present, my country's Poplar is rich in resources and has a large stock volume, but the wood has its disadvantages, mainly manifested as dry shrinkage, wet expansion, easy deformation, anisotropy, and easy degradation and decay under the action of water, heat, light, and microorganisms. Easy to burn etc. Wood itself also has inevitable defects. According to the national standard "Wood Defects" (GB155-84), wood defects are divided into nine categories: knots, decay, insect damage, cracks, trunk shape defects, wood structure defects, scars, Unusual deposits and woodworking defects. Most of these defects are caused during the growth of trees and are unavoidable. Among them, the defects that have a greater impact on the material of structural materials are knots, decay and cracks. These deficiencies largely restrict the application of wo...
