Abstract

A bamboo layer levels sheet panel belongs to bamboo products technology and is characterized in that the bamboo layer levels sheet is staggered by component units of green surface and yellow surface bamboo plates, same layer bamboo plates with same directional green surface and yellow surface are laterally spliced, each yellow surface turns to center line and green surface turns back to the center line, integral intensity of the bamboo layer levels sheet panel in the utility model has been improved homogeneously, capability becomes more stable, that is applicable of vane of windmill generator and even part of components in aviation field, and has advantages of abundant and cheap material resources and low production cost, in the meantime, the utility model avoids or decreases usage of fiber glass and carbon fiber which benefits environment protection.

Description

A kind of bamboo level sheet material

Technical field

The utility model belongs to the bamboo product technical field, relates to a kind of high-intensity bamboo level sheet material.

Background technology

The blade of traditional wind-driven generator is a fiberglass blade, if blade is longer than 30 meters, generally needs to add carbon fiber, to remedy the deficiency on the strength and stiffness.Yet the carbon current fiber not only costs an arm and a leg, and seriously supply falls short of demand.With the primary structure body of high-strength bamboo level sheet material as blade, rational in addition Airfoil Design, or even the blade more than 40 meters can avoid using carbon fiber.And common bamboo lumber can't satisfy above-mentioned requirements at present, how to utilize high-strength bamboo level sheet material to make the problem that the partial component in blade of wind-driven generator even the aviation field also more and more becomes the correlative technology field common concern and tries hard to solve.

Technology contents

The purpose of this utility model is to overcome problems of the prior art, and a kind of high-strength bamboo level sheet material that is suitable for blade of wind-driven generator, the use of aviation field partial component is provided.

The utility model is achieved through the following technical solutions:

A kind of bamboo level sheet material is characterized in that with the bamboo chip that comprises bamboo strip, yellow bamboo face serving as to constitute unit formations that be staggered, and bamboo strip, yellow bamboo face splice towards the same layer bamboo chip side direction of unanimity, and each layer yellow bamboo face is towards center line, and bamboo strip is center line dorsad.

Described a kind of bamboo level sheet material is characterized in that described bamboo chip thickness is 0.5～2.5mm, and width is 2～15mm.

The raising that obtains homogenizing of the bulk strength of the utility model bamboo level sheet material; performance is also more stable; be suitable for the partial component in blade of wind-driven generator even the aviation field; and raw material sources are abundant, cheap; low cost of manufacture; simultaneously, avoid or reduce and use glass fibre, carbon fiber, help environmental protection.

Description of drawings

Accompanying drawing 1 is a structural representation of the present utility model

The specific embodiment

With thick bamboo tube cut growth bamboo bar, reject the surf green top layer of 0.2～0.4mm, further the bamboo bar being cut into thickness is 0.5～2.5mm, and width is the bamboo chip 1 of 2～15mm, with the bamboo chip 1 that comprises bamboo strip 2, yellow bamboo face 3 serves as to constitute the unit formation that is staggered, as shown in the figure 1.Bamboo strip 2, yellow bamboo face 3 splice towards same layer bamboo chip 1 side direction of unanimity, each layer yellow bamboo face 3 is towards center line 4, bamboo strip 2 is center line 4 dorsad, that is: the adjacent bamboo chip green grass or young crops of individual layer, that yellow face is same direction is regularly arranged, level material symmetry middle part is that yellow face and yellow face glued joint, be up and down that blue or green face and yellow face glued joint between two half storeys and the layer, behind the assembly, hot-forming under certain pressure.

Use high-strength bamboo level board making blade of wind-driven generator, use glass fibre, substitute and use carbon fiber, thereby reduced the cost of raw material because of reducing; High-strength bamboo level sheet material blade has speed of production, lower initial outlay, human cost still less faster simultaneously, thereby has reduced production cost; Because mao bamboon is the material of natural, environmental protection and sustainable use, can't use or useful life finish after the mao bamboon material can degrade, for the environmental protection treatment of waste product is provided convenience; The process of use mao bamboon manufacture of materials has not only significantly reduced the discharging of carbon equivalent, and compares with carbon fiber, glass-reinforced plastic material, and it also is minimum that its unit makes energy consumption.

Claims (2)

1. bamboo level sheet material, it is characterized in that with the bamboo chip (1) that comprises bamboo strip (2), yellow bamboo face (3) serving as to constitute the unit formation that is staggered, bamboo strip (2), yellow bamboo face (3) splice towards same layer bamboo chip (1) side direction of unanimity, each layer yellow bamboo face (3) is towards center line (4), and bamboo strip (2) is center line (4) dorsad.

2. a kind of bamboo level sheet material according to claim 1 is characterized in that described bamboo chip (1) thickness is 0.5～2.5mm, and width is 2～15mm.
