How many manifestations of the appearance of carbon fiber board?

Both carbon fiber board and carbon fiber tube are the most basic products of carbon fiber composite materials, which can be used in the production of fixtures, medical boards, military boxes, drone parts and other products. The carbon fiber board is made of carbon fiber prepreg laid and laminated at a specific angle, and it is shown to everyone in the following patterns.

1-Plain weave

The figure below shows the standard 1x1 top and bottom knitting pattern. Since the yarn is more interwoven in the plain weave, the weave is more stable and easier to handle than the twill weave. The strength of the plain weave laminate is not as strong as the tightly packed laminate of the twill weave, but it is easier to conform to the complex curves of certain components.

2-Twill weave

Twill weaves are usually provided in 2x2 or 4x4 top/bottom weave patterns. Twill weaves have a more modern appearance and are more popular with consumers. In 2x2 knitting and 4x4 knitting, the interlaced knitting pattern produces a diagonal appearance. Twill weave has fewer stress points than plain weave. But when manufacturing carbon fiber sheets, twill weave carbon fiber cloth must be more careful to avoid deformation during the weaving process.

3-Harness Satin Weave

In satin weaving, the weft yarn passes through multiple warp yarns before passing through one warp yarn. Common satin weaves include 4-wire satin (4HS), 5-wire satin (5HS) and 8-wire satin (8HS). As the number of satin weaves increases, the formability will increase, and the fabric stability will decrease. Satin weave is more flexible than plain or twill weave and can be easily formed around complex contours, but it is less stable to weave deformation.

4-Honeycomb weave

In the honeycomb structure, carbon fiber is woven into a honeycomb pattern, which can be used as a covering for a large surface and for beautiful decorative modification. Because the local thickness and strength change with the winding of the decorative weaving pattern. Therefore, it is also relatively rare in structural parts.

When choosing weaving for carbon fiber boards, strength, appearance, and other requirements should be considered. Different weaving methods will distribute force in different directions, and the lamination strength will vary according to the layup and molding conditions. The looser the weave, when the carbon fiber is woven into a complex curve, there will be more gaps between the fibers. On the other hand, a looser braid makes it easier to drape the carbon fiber braid around the same complex curve.
