Getting Started with Carbon Fiber Weaving
Fiberglass is the “workhorse” of the composites industry. Due to its strength and low cost, it is used in a large number of applications.
However, when more needs arise, other fibers can be used. Carbon fiber braid is an excellent choice due to its light weight, high stiffness and conductivity, and appearance.
The aerospace, sporting goods and automotive industries all make good use of carbon fiber. But how many types of carbon fiber are there?
Carbon Fiber Braid Explained
Carbon fiber is a long, thin chain, mostly carbon atoms. The crystals inside are arranged in such a way that they are very strong in size, like a spider web.
Due to its high strength, carbon fiber is difficult to break. Also resists bending when tightly woven.
On top of that, carbon fiber is potentially eco-friendly, so it produces less pollution than other similarly used materials. However, recycling and reuse is not so easy.
Different types of carbon fiber weaves
There are many different types of carbon fiber braids available for purchase. Here are some of the main differences in carbon fiber types, and why you should choose one over the other.
2×2 twill weave
You will find that the most common type of carbon fiber weave is a 2×2 twill weave. It is used in many decorative applications but also has moderate formability and stability.
As the name suggests, each tow goes through 2 tows and then two tows. This weave makes it more supple and easy to apply.
The only downside is that this type of braid needs to be handled more carefully than other braids as they can accidentally leave a slight distortion in it.
Plain weave 1×1 weave
The second most commonly used carbon fiber weave is the plain weave or 1×1 weave. It looks more like a checkerboard because of the pattern in which 1 bunch drags onto and under another bunch.
As a result, its weave is tighter and harder to twist. However, it is also more difficult to coat over molds than twill weave.
A unidirectional carbon fiber fabric isn’t actually a weave at all, it’s a non-woven fabric composed of fibers that are parallel to each other.
There are no gaps between the fibers and all the strength is concentrated along its length. In fact, this gives it a much stronger longitudinal stretch potential than other weaves.
You typically see this carbon fiber fabric used where front and rear strength is important, such as in tubular construction. It can also be used in architectural and structural engineering.
