How to identify carbon fiber?

High strength and high modulus fiber with more than 90% carbon content. High temperature resistance ranks first in all chemical fibers.Acrylic fiber and viscose fiber are used Carbon fiber is a high-strength and high-modulus fiber with a carbon content of more than 90%, and its high temperature resistance ranks first among all chemical fibers. Acrylic fiber and viscose fiber are used as raw materials and carbonized by oxidation at high temperature. It is an excellent material for manufacturing aerospace and other high-tech equipment. But how to confirm the quality of carbon fiber?

Check the back or inside of the product

An easy way to distinguish between solid carbon fiber components and carbon / glass fiber components is to check the back or interior of the product. Real carbon fiber parts still look like carbon fiber from the back. In other words, you will be able to see the actual fibers of carbon. Depending on your choice of carbon fiber finish, it may be matte or glossy, but the gloss will be quite uniform.

By contrast, fiberglass parts look like a piece of fiberglass cloth. When you move it in the light, there are usually some areas that are brighter than others. This shows that the part is formed using a “wet” process, in which a layer of carbon fiber, then several layers of glass fiber, is then placed into the mold, then poured, brushed and cured. In addition, there is light passing through the single layer of carbon on the fiberglass.

Check the weight of the product

Glass fiber is heavier than carbon fiber, and glass fiber products with carbon fiber skin are about 70% heavier than real carbon fiber. In addition, the wet paving process adds extra weight because excess epoxy resin is not extracted from the material through a vacuum, as vacuum bags or epoxy resin filling are usually used for higher quality carbon fiber components.

Check the edge of the product

The wet paving process adds extra weight because excess epoxy resin is not extracted from the material through a vacuum, as vacuum bags or epoxy resin filling are usually used for higher quality carbon fiber components.
