As a representative of new composite materials, carbon fiber materials are often compared with other materials. We are a manufacturer specializing in carbon fiber products. In daily consultation, some customers will compare carbon fiber with glass fiber. This article will focus on this. Let me talk about the performance advantages and disadvantages of the two materials, so that you can better choose the material that suits you.
Advantages and disadvantages of carbon fiber materials:
advantage:
1. The density is extremely low, only 1.5g/cm3, which makes the carbon fiber products much lighter than other material products. This will have a very high specific strength and specific strength, which makes The reason why carbon fiber products have been widely used in many fields is that they are lightweight and have very high strength properties.
2. Extremely high acid and oxidation resistance, which allows carbon fiber materials to be used normally in many harsh environments, including not corroding when exposed to organic solvents. It is used in medical equipment and industrial equipment in harsh environments. The environment also has very good application performance.
3. Low thermal expansion coefficient. Carbon fiber material has a very low thermal expansion coefficient. When it is subject to thermal expansion and contraction, the overall change is very small. The entire carbon fiber product will not deform with the change of temperature difference. For example, you can add a carbon fiber cone telescope to the application product. , carbon fiber measuring instrument, etc.
4. It has very good X-ray transmittance, which has very high application advantages for products that require medical equipment, such as carbon fiber medical bed boards.
5. In terms of performance, such as Young’s modulus, it is more than 2 times higher than that of glass fiber, and compared with Kevlar material, it is more than twice as high.
6. It has very good designability advantages and can complete the integrated molding of products, reducing the need for assembly and better ensuring the high-performance advantages of carbon fiber products.
Disadvantages:
1. Although carbon fiber materials have relatively high strength and a very high Young’s modulus, they are still brittle materials. If the force exceeds its own limit, it will break, but not completely, and there is no way to repair it.
2. The entire carbon fiber material has extremely high tensile strength, but its performance after molding needs to be continuously tested. If the performance requirements are very precise, it is related to the matrix material, and complex testing is required. Stress calculation.
3. There is no way to recycle. Nowadays, carbon fiber products made of epoxy resin-based thermosetting carbon fiber composite materials are widely used. The recyclability of carbon fiber products made of this composite material is low and recycling is difficult.
Advantages and disadvantages of fiberglass materials:
advantage:
1. It has very good electrical insulation, which can be well applied to the electronic field and better ensures the superior performance of product applications.
⒉It has very good elastic coefficient and rigidity, which can meet the basic certain performance of the product.
3. Processability, it can complete product processing very well, and can be made into products of different shapes such as strands, bundles, felts, and woven fabrics.
4. Cheaper price and easy to achieve mass production.
5. It has a certain degree of transparency, which is a very good advantage for some products that require permeability.
6. It has very good dimensional stability and can extremely ensure the performance advantages of glass fiber products.
shortcoming:
1. If you look purely at strength, it is still inferior to metal materials or the fiberglass materials we mentioned in this article.
2. The high temperature resistance is still not enough and cannot exceed 100 degrees Celsius.
The above is the interpretation of carbon fiber and glass fiber. Although both are fiber composite materials, they still have many differences. The entire application fields are also very different, so there is more to choose from. It still depends on the performance of our products. If necessary, if you have insulation needs, it is better to use glass fiber. If it is used for automotive products, it must be the high strength provided by carbon fiber. , the demand for lightweight North is better.
