Decoding Characteristics of Different Braiding Ways of Carbon Fiber Fabric

Decoding Characteristics of Different Braiding Ways of Carbon Fiber Fabric

1.

Characteristics of plain Carbon Fiber Sheet:

Plain weaving is characterized by interweaving warp yarn and weft yarn on top and down regularly.

That is to say, warp and weft yarns are interlaced every other yarn, so the most interlacing points make the fabric firm, wear-resistant, stiff and smooth, but less elasticity, general gloss, plain weave fabric density can not be too high, lighter, better wear resistance, better air permeability, uniform fabric surface and the same front and back.

This kind of carbon fiber bundle has many bending points and high elongation in the process of tension because it is always in the ups and downs state.

At the same time, due to the position of the interlacing points of two adjacent warp yarns and two adjacent weft yarns, eyeholes appear due to the sliding of the fibre bundles.

Variations of plain weaving are also numerous, such as 12K warp and 1K weft mixed weaving.

The plain woven fabrics have a checkerboard-like appearance due to the different reflections of fibre bundles in the warp and weft directions.

2.

Characteristics of Twill carbon fiber sheet:

The twill knitted fabric has a diagonal pattern which has an angle with the arrangement direction of the fiber bundles.

There is no fiber bundle in this direction, but because of the warp and weft knitting process of the fiber bundles, the warp or weft fiber bundles skip over two weft or warp fibers for knitting.

That is to say, the braiding frequency of fiber bundles decreases, the floating length of fiber bundles increases, and two adjacent fiber bundles stagger one braiding position.

In this way, the diagonal pattern of twill knitted fabric is formed.

This twill appearance has a strong three-dimensional sense, used for automotive refitting products, such as panels, hood, exhaust cylinders and so on.

3.

Characteristics of Satin/forged carbon fiber sheet:

Forged weaving has a regular and uniform distribution of separate and discontinuous warp-knitting points (or weft-knitting points) in the weave cycle, which is called Satin weaving.

It is characterized by long warp (or weft) floats and fewer interlacing points. Although they form diagonal lines, they are not continuous, and the distance between them is regular and uniform.

This fabric structure is called Satin weave. Satin fabric warp yarn and weft yarn are interwoven at least once every three, so this knitting structure makes the fabric denser and thicker.

This satin fabric has smooth and smooth surface, soft texture, shiny or slightly grain. The strength of this kind of fabric is lower than plain and twill.

These three kinds of braiding patterns have different strength due to the influence of bending and other fiber bundles.

The strength of carbon fiber braided fabric can be characterized by tensile force, tearing force, bursting force, bending force, etc.

These are also different with the different braiding methods.

Generally speaking, the tensile strength in the direction of the arrangement of carbon fiber bundles is related to the strength and friction of the fibers.

On the one hand, the tensile force can be divided into parallel and vertical directions.

The parallel direction force requires high fiber strength, while the vertical direction force is related to the resistance of the braiding form to the fiber bundle.
