Carbon fiber plate material and manufacturing method thereof

Abstract

The invention relates to a carbon fiber plate and a manufacturing method thereof. The carbon fiber plate is formed by laminating and curing several unidirectional carbon fiber cloths impregnated with resin. The unidirectional carbon fiber cloths are divided into an upper layer group, a middle layer group and a lower layer group to form the upper layer group. Each carbon fiber cloth is stacked in different directions with the carbon fiber filaments of the adjacent carbon fiber cloth layers, the carbon fiber filaments of the carbon fiber cloths in the middle group are laid in the same direction, and the carbon fiber cloths in the lower group are laid in different directions with the carbon fiber filaments of the adjacent carbon fiber cloths. The carbon fiber filaments of the two carbon fiber cloths adjacent to the middle group and the lower group are laminated in different directions, and the carbon fiber filaments of the two carbon fiber cloths adjacent to the middle group and the upper group are laminated in different directions. The advantage of the carbon fiber plate and its manufacturing method of the present invention is that it can solve the problem of surface cracking without affecting the thickness and strength of the carbon fiber plate and without changing the raw material of the carbon fiber plate.

Description

technical field [0001] The invention relates to a carbon fiber plate and a manufacturing method thereof. Background technique [0002] The carbon fiber sheet forming process is to use unidirectional carbon fiber cloth (unidirectional carbon fiber cloth refers to a large number of carbon fiber filaments in one direction, and only a small amount of carbon fiber filaments in the other direction) impregnated with resin and then laminated and cured. The main purpose In terms of building reinforcement, it is characterized by high axial tensile strength, corrosion resistance and earthquake resistance, and its weakness is that it has low performance for compression members, shear members and members with complex forces. [0003] The carbon fiber sheet is formed by laminating and curing several unidirectional carbon fiber cloths impregnated with resin. one up one down) for laying up, ideally as attached figure 1 As shown, in fact, as attached figure 2 As shown, the layers of the ...

The main purpose In terms of building reinforcement, it is characterized by high axial tensile strength, corrosion resistance and earthquake resistance, and its weakness is that it has low performance for compression members, shear members and members with complex forces

[0003] The carbon fiber sheet is made of several unidirectional carbon fiber cloth impregnated with resin and then laminated and cured. one up one down) for laying up, ideally as attached figure 1 As shown, in fact, as attached figure 2 As shown, the layers of the unidirectional carbon fiber cloth 100 are interwoven with each other (each unidirectional carbon fiber cloth 100 is uneven). (shown) will cut at least two unidirectional carbon fiber cloths 100 at the same time, which will destroy the texture of the unidirectional carbon fiber cloth layer, and the textures between layers will interlace with each other and produce broken lines, which will affect the appearance
