Carbon fiber composite materials have a wide range of applications in the aviation industry, industrial manufacturing, automobile production, medical equipment, rail transit and other fields. Carbon fiber composite materials have a series of advantages such as light weight, high strength, corrosion resistance, good electrical conductivity, and good electromagnetic shielding effects. The more people recognize it. However, the production process of carbon fiber and carbon fiber composite products is not fully understood, so there are still many questions in practical applications.

The more people recognize it. However, the production process of carbon fiber and carbon fiber composite products is not fully understood, so there are still many questions in practical applications.
1. Is there a unified reference data for the performance of carbon fiber products?
The properties of specific carbon fiber precursors are fixed. For example, Toray's carbon fiber precursors, T300, T300, T400, T00, etc., have a series of parameters that can be traced. However, there is no uniform standard to measure carbon fiber composite products. First, the different types of raw materials selected will lead to different product performance, and the choice of matrix and product design will lead to different product performance.
2.Are carbon fiber composite products very expensive?
The price of carbon fiber composite products is closely related to the price of raw materials, the level of technology and the quantity of products. Some products have higher industrial environment requirements and have special requirements for the performance and material of carbon fiber products. This requires the selection of specific raw materials. The higher the performance of the raw materials, the more expensive they are.
However, after a certain carbon fiber product is mass-produced, the larger the order, the lower the cost allocated to each product. From a long-term perspective, the superior performance of carbon fiber will prolong the service life of the product, reduce the number of maintenance, and it is also very beneficial to the reduction of the use cost.
3. Why do carbon fiber composite products need to be customized with drawings/samples, and also need to open the mold?
The price of carbon fiber composite materials is high, and it is difficult to achieve large-scale mass production except for the commonly used carbon fiber tubes and carbon fiber boards of several specifications. The specificity of the finished product is high. Generally, manufacturers of carbon fiber composite products do not have excess finished products in stock. Moreover, most carbon fiber composite materials are used as parts to replace traditional metal materials. Therefore, it must be customized according to the detailed drawings or real samples provided by the customer.
Not all carbon fiber products need to open molds. In some products with complex designs and high performance requirements, especially in the case of a large number of customizations, molds are required. Moreover, the production process of carbon fiber composite products is different, such as molding, vacuum autoclave, etc. Whether or not the mold needs to be opened is still to be judged according to the product drawings.
4. Are carbon fiber composite products toxic?
Carbon fiber composite materials are made by mixing carbon fiber raw filaments with ceramics, resins, metals and other matrices, and are generally not toxic.
5.Are the carbon fiber composite products all black with woven texture?
The color and texture of carbon fiber composite products can be customized. The direction of the texture is determined by the design of the pre-layup. The default initial color is black. Of course, the color can also be changed by later painting. Not only that, you can print your own patterns or logos on carbon fiber products.
6. What is the difference between thermoset carbon fiber composite material and thermoplastic carbon fiber composite material?
Thermosetting carbon fiber composite materials tend to have a curing agent's role in curing and molding. Thermoplastic carbon fiber composite products mainly rely on cooling to achieve shaping.
Thermoplastic carbon fiber composite materials are not widely used in thermosetting carbon fiber composite materials. The main reason is that they are expensive and are generally used in high-end industries.
The thermosetting carbon fiber composite material is difficult to recycle due to the limitation of the resin matrix itself, and it is generally not considered; the thermoplastic carbon fiber composite material can be recycled, and it can be produced twice as long as it is heated to a certain temperature.
