Composite material refers to a new type of material that is fused together from a variety of materials. The carbon fiber material we often say is a composite material and is called “black gold” in composite materials. Carbon fiber composite materials are composed of carbon fiber tow and matrix materials. (Matrix materials such as resin, ceramics, metal, etc.) combined materials, the extremely high performance advantages make it a good ban on traditional materials. This article will talk about the high-performance advantages of carbon fiber composite materials.
1. Very low density
The density of carbon E-dimensional composite material is very low, the density is only about 1.5gcm3. Compared with metal materials, such as steel with a density of 7.8gycm3 and aluminum alloy with a density of 2.8glcm3, this pair can find that carbon fiber composite materials have a very low density, the overall weight of the product made of this material is also very light, and it has a very good lightweight effect in many fields, which is a performance that traditional metal materials do not have.
⒉ extremely high strength
The broken fiber material has a very high strength performance, which can reach a tensile strength of 350OMPa. Compared with steel, the tensile strength of steel is 65OMPa, and the tensile strength of aluminum alloy is 42OMPa. In this way, it can be found that the high strength performance of carbon fiber is very good. High, can make the strength performance of the product perfectly meet the previous needs of the product, even if the carbon fiber is anisotropic, it will still be much higher than the strength of the metal material product.
3. Good corrosion resistance
Carbon fiber material has very good performance advantages of acid resistance, alkali resistance and oxidation resistance, which makes carbon fiber material have the advantages of multi-environmental application, such as wet environment or carbon fiber products that are often exposed outdoors, not easy to rust or window corrosion, with very high application performance.
4. Good impact resistance
Carbon fiber material has very good impact resistance. After being made into carbon fiber products, it has very good impact resistance in the event of a mass collision. To ensure the safety of the car, because the inside of the carbon fiber product is a carbon filament, which is well connected through the matrix material, so that the force can be well dispersed when the force is applied.
5. Good machinability
Carbon fiber materials have inherited the flexibility of fibers very well, which makes carbon fiber products made of carbon fiber materials have a very good design, and can be designed flexibly according to customer product requirements, making the overall performance of the product better. It can meet the requirements, and can also carry out interlayer design in the middle of the product. For example, there are such application designs on medical equipment and high-speed trains. The light star display performance is better, and it also has a good force direction design. , so it is more convenient for the actual application of the product.
6. Low coefficient of thermal expansion
Carbon fiber material has a very low coefficient of thermal expansion, which also has a very good performance application advantage in some carbon fiber products that require precision, such as telescopes, precision rulers, including Xuan Renwei in aerospace and other fields. Products can make the overall performance advantage better.
