Abstract

The utility model discloses a carbon fiber sheet enhanced poplar veneer laminated timber structural component which is characterized in that the carbon fiber sheet enhanced poplar veneer laminated timber structural component is formed by staggering, overlapping and gluing poplar rotary-cut sheets (1) and carbon fiber sheets (2). The carbon fiber sheet enhanced poplar veneer laminated timber structural component gives full play to the advantages of carbon fiber sheets and poplar veneer laminated timbers, greatly improves the mechanical properties of poplar materials, improves the additional production values and technological contents of poplars and greatly expands the application field of poplars. Moreover, the carbon fiber sheet enhanced poplar veneer laminated timber structural component can avoid the common problems like invalid anchoring, peeling and destroying, etc, when externally sticking carbon fiber sheets, is more possible to give full play to the intensity of the carbon fiber sheets and drives large wood structural component production to be possible.

Description

Carbon fiber fabric reinforced poplar laminated veneer lumber structural element
Technical field
The utility model relates to the member that a kind of carbon cloth combines with the board using poplar board layer.
Background technology
The meaning poplar aboundresources of present China, accumulation is big, but this timber has its shortcoming, mainly shows as drying shrinkage, wet rising, and yielding, anisotropy is easy to degraded, rotten, easy firing etc. under water, heat, light, microbial action.Also there is inevitable defective in timber itself, by national standard " defects in timber " (GB155-84), defects in timber are divided into nine big classes promptly: knot, rotten, insect pest, crackle, stem form defective, wood structure defective, scar, abnormal deposit and timber manufacturing deficiency.These defectives cause in the arboreal growth process mostly, are inevitable.Wherein, be knot, rotten and crackle to the bigger defective of structure material material influence.These weak points have restricted the application of timber on engineering structure to a great extent.
Along with the great variety of world forest resources structure, high-quality timber resources is more and more rare, and people improve constantly the demand of wood-based product and the requirement of ecological environment, and the wood materials disparities between supply and demand become clear day by day.Along with the minimizing of big footpath level timber and the raising of timber serviceability requirement, the natural characteristic of original timber is difficult to satisfy the demand.Timber is processed into constituent elements such as plank, batten, veneer, wood shavings or fiber, utilize modern technologies that the timber constituent element is reassembled as the novel wooden material, as glue together that wooden frame, laminated veneer lumber, orientation are become a useful person, glued board, recombinant decorative veneer, laminated veneer lumber hollow circuit cylinder material, oriented wood chipboard, particieboard and fiberboard etc., these wooden recombined materials have the not available geometrical performance of original timber, homogeneity, uniformity and curve generating.
Laminated veneer lumber ((Laminated Veneer Lumber, be called for short LVL) is to be primary raw material with small dimension wood and low-quality material log, is peeled into veneer, becomes a useful person through rift grain assembly, gummed, hot-forming novel artificial.Laminated veneer lumber has not only kept the natural characteristic of timber, and the knot of log itself, crackle, defective random dispersal such as rotten be in material, and intensity and other physical properties are evenly and be higher than log, steady quality.
In short supply along with timber resources, utilize artificial fast-growing woods timber to make laminated veneer lumber and just becoming trend, be combined into new composite wooden material with timber and other material simultaneously and also become the research focus, relevant data shows: the bending strength of composite wooden material is three times of dimension stock of normal intensity grade, and rigidity improves 30%.It can not only keep former one-component material characteristic separately, and can performance complement, makes material have the excellent comprehensive performance.It is to alleviate the timber resources anxiety and promote one of effective way of the timber industrial structure that artificial fast-growing woods timber and composite wooden material are used.
With the poplar is that laminated veneer lumber is made on the basis, has not only brought into play himself advantage, has overcome the defective in material of poplar own and the processing, and intensity and other physical and mechanical property all are higher than poplar itself, and simultaneously, volume recovery is higher, remarkable in economical benefits; Compare log, laminated veneer lumber is more likely made the large scale structural elements.But the tensile strength of laminated veneer lumber is not high, and state many laminated veneer lumbers manufacturing enterprise can only produce non-structure and use poplar laminated veneer lumber as packaging material, influences the scope of application of poplar laminated veneer lumber.
Summary of the invention
The purpose of this utility model is exactly the above-mentioned deficiency at prior art, provide a kind of can be made into large-size components, in light weight, be subjected to the high carbon fiber fabric reinforced poplar laminated veneer lumber structural element of force intensity.
The technical solution adopted in the utility model is as follows:
A kind of carbon fiber fabric reinforced poplar laminated veneer lumber structural element is characterized in that it is to be formed by poplar rotary-cut sheet and carbon cloth intersecting gummed.
The thickness of described poplar rotary-cut sheet is less than 2mm.
Pass through the epoxy resin glue bond between described poplar rotary-cut sheet and the carbon cloth.
The beneficial effects of the utility model have:
Give full play to the advantage of carbon cloth and meaning poplar laminated veneer lumber, greatly improved the mechanical property of meaning poplar material, improved poplar production added value and scientific and technological content, expanded the application of meaning poplar greatly.And problem such as common anchoring inefficacy and stripping damage in the time of can avoiding carbon cloth to paste outward, carbon cloth intensity more can be given full play to, and makes large-scale wood structures production become possibility.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model is further described below in conjunction with accompanying drawing:
As shown in Figure 1, the utility model is to be formed by poplar rotary-cut sheet 1 and carbon cloth 2 mutual stacked gummeds, by their combination, has greatly improved the mechanical property of meaning poplar material.The thickness of described poplar rotary-cut sheet 1 is less than 2mm, and between poplar rotary-cut sheet 1 and the carbon cloth 2 by the epoxy resin glue bond.
Other undeclared part of the utility model is same as the prior art.
