Description

A kind of carbon fiber sheet

Technical field

The utility model is related to a kind of carbon fiber sheets.

Background technology

Carbon fiber sheet moulding process is that (unidirectional lamination refers to have in one direction big using unidirectional lamination The carbon fiber wire of amount only has a small amount of and typically thin carbon fiber wire in other direction) curing molding is laminated after impregnating resin, In terms of main application is building reinforcement and strengthening, its main feature is that axial tensile-strength is high, corrosion resistance and shock resistance, weakness are pair It is relatively low in compression member, shear component and its performance of the component of stress complexity.

Carbon fiber sheet by being laminated curing molding after several unidirectional lamination impregnating resins, common laying mode be by Several-90 degree of 100-0 degree of luxuriant 0 degree of-90 degree of carbon fiber wire arragement direction of unidirectional lamination (vertical and horizontal are one on the other) Laying is carried out, ideally as shown in Figure 1, in fact, as shown in Figure 2, unidirectional lamination 100 is between layers It is can be interweaved (each unidirectional lamination 100 is rough), during milling carbon fiber sheet, a milling plane 200 (in figures shown in dotted line) can switch at least two unidirectional laminations 100 simultaneously, thus can destroy unidirectional lamination Lines possessed by this layer, lines between layers can be interlaced and line is broken in generation, influences beauty.

The content of the invention

It can not influence carbon fiber board thickness, intensity the purpose of this utility model is to provide a kind of and not change carbon fiber The carbon fiber sheet that face is added to break line is solved the problems, such as in the case of the raw material of plate.

To achieve the above object, the utility model uses following technical scheme：

A kind of carbon fiber sheet is molded by being laminated curing after several unidirectional carbon cloth impregnating resins, and feature exists In, unidirectional carbon cloth is divided into upper layer group, middle level group and lower floor's group from top to bottom according to the difference of carbon fiber wire arragement direction, Each carbon cloth for forming upper layer group is the incorgruous laying of carbon fiber wire of adjacent carbon fibre cloth layer, forms each carbon fiber of middle level group The carbon fiber wire laying in the same direction of cloth, each carbon cloth for forming lower floor's group is the incorgruous laying of carbon fiber wire of adjacent carbon cloth, The incorgruous laying of carbon fiber wire of middle level group two carbon cloths adjacent with lower floor group, middle level group two carbon fibers adjacent with upper layer group The incorgruous laying of carbon fiber wire of cloth.

The utility model has the advantage of can not influence carbon fiber board thickness, intensity and the former material for not changing carbon fiber board It is solved the problems, such as in the case of material plus line is broken in face.

The utility model can be improved by following scheme：

Each carbon cloth for forming upper layer group is according to its carbon fiber wire vertical and horizontal arrangement mode laying one on the other, structure Each carbon cloth into lower floor's group is according to its carbon fiber wire vertical and horizontal arrangement mode laying one on the other, middle level group and lower floor The adjacent carbon cloth of group is according to its carbon fiber wire vertical and horizontal arrangement mode laying one on the other, middle level group and upper layer group phase Adjacent carbon cloth is according to its carbon fiber wire vertical and horizontal arrangement mode laying one on the other.

At least two layers of each carbon cloth of composition middle level group.

Description of the drawings

Specific embodiment

It is below in conjunction with the accompanying drawings and real in order to which those skilled in the art is made to more fully understand the technical solution of the utility model Applying example, the utility model is described in further detail.

As shown in Figure 3, a kind of carbon fiber sheet is impregnated by several (being 8 layers shown in figure) unidirectional carbon cloth 100 Lamination cures and is molded after resin, and unidirectional carbon cloth 100 is divided into from top to bottom according to the difference of carbon fiber wire arragement direction Upper layer group 1 (2 layers are shared shown in figure), middle level group 2 (having three layers altogether shown in figure) and lower floor's group 3 (having three layers altogether shown in figure), At least two layers of each carbon cloth 100 of composition middle level group 2.

Each carbon cloth 100 for forming upper layer group 1 is the incorgruous laying of carbon fiber wire of adjacent carbon cloth 100, in composition The carbon fiber wire laying in the same direction of each carbon cloth 100 of layer group 2, each carbon cloth 100 for forming lower floor's group 3 is adjacent carbon fiber The incorgruous laying of carbon fiber wire of cloth 100, the incorgruous paving of carbon fiber wire of two carbon cloths 100 adjacent with lower floor group 3 of middle level group 2 It is folded, the incorgruous laying of carbon fiber wire of two carbon cloths 100 adjacent with upper layer group 1 of middle level group 2.

Specifically, each carbon cloth 100 for forming upper layer group 1 is according to its carbon fiber wire vertical and horizontal arrangement mode one On once laying, each carbon cloth 100 for forming lower floor's group 3 be according to its carbon fiber wire vertical and horizontal arrangement mode one on the other Laying, the carbon cloth 100 adjacent with lower floor group 3 of middle level group 2 is according to one on its carbon fiber wire vertical and horizontal arrangement mode one Lower laying, the carbon cloth 100 adjacent with upper layer group 1 of middle level group 2 are according on its carbon fiber wire vertical and horizontal arrangement mode one Laying once.

The manufacturing method of carbon fiber sheet introduced below, it includes the following steps：1), several unidirectional carbon cloths are provided 100；2), above-mentioned carbon cloth 100 is impregnated in resin solution, the above-mentioned impregnated each carbon cloth 100 of hot pressing is with formation Carbon fiber sheet, after step 1), according to where the processing of the thickness of unidirectional lamination 100 and product calculates machined surface Layer, according to the carbon of the carbon fiber wire of the carbon cloth 100 where the machined surface calculated unidirectional lamination 100 adjacent thereto Filament is in the same direction.

It is further preferred to mode be adjacent thereto according to the carbon fiber wire of the carbon cloth 100 where the machined surface calculated The carbon cloth of two layers of unidirectional up and down 100 carbon fiber wire it is in the same direction.

The carbon fiber board produced according to this manufacture, in following process milling carbon fiber sheet, a milling Tangent plane 200 (in figure shown in dotted line) can switch at least two unidirectional laminations 100 simultaneously, without destroying Unidirectional Lines possessed by this layer of fiber cloth, avoid lines between layers can be interlaced and generate broken line, improve aesthetics.
