What is the difference between plain weave and twill weave of carbon fiber?

Carbon fiber is a kind of special fiber composed of carbon elements. It has the characteristics of high temperature resistance, friction resistance, electrical conductivity, thermal conductivity and corrosion resistance, which is fibrous, soft and can be processed into all kinds of fabrics. because of the preferred orientation of its graphite microcrystal structure along the fiber axis, it has high strength and modulus along the fiber axis. The density of carbon fiber is small, and the main use of carbon fiber is to composite with resin, metal, ceramic and carbon as a reinforcing material to make advanced composite materials.

Plain and twill weave is widely used in the surface lines of carbon fiber. Twill weave has a three-dimensional sense, plain weave is relatively dense and has excellent strength. So what’s the difference between them?

Plain Weave

It is made by weaving each other on both sides of the weft thread. Plain woven carbon fiber board looks symmetrical, with a small chessboard-style appearance. In this weaving, the tow is woven into a top / bottom pattern. The short spacing between interweaves makes the plain pattern have high stability. Fabric stability refers to the ability of the fabric to maintain its knitting angle and fiber orientation. Because of this high degree of stability, plain pattern is not very suitable for cascading with complex contours, and it is not as flexible as some other tissues. Because of its interweaving point, the plain material shows low bending strength, tensile strength slightly higher than twill, and it is with low balance.

Twill Weave

It is characterized by diagonal lines formed by weave points or weft weave points, so there are fewer nodes for plain weave. Twill weave has good softness and can form complex contours. Along the direction of the twill braided tow, it passes through a certain number of tows, and then through the same number of tows. Twill has fewer nodes than plain, but the permeability of resin is indeed higher than that of the plain. In general, the tensile strength of the plain weave of carbon fiber board is lower than that of twill, so the stress strength is often lower than that of twill, mainly because of the good permeability of resin. Twill has a strong three-dimensional sense.

There is a structural difference between plain and twill. Plain weave has a smaller and more compact style and generally a more subtle appearance. If you like exquisite, plain is a better choice. Twill is flexible and can form complex contours while maintaining good stability. It must be treated more carefully than plain fabrics to avoid increasing tissue deformation. There is no standard answer to the question of which pattern is better, which mainly depends on personal preference. Vikicarbon can provide you with two choices, you can choose according to your actual needs.
