Advantages of carbon fiber - replacing metal with polymer
In the application of industrial design, the traditional technology usually uses aluminum or alternative metal alloy materials, because the performance of metal parts is better and meets the requirements of this kind of tools. In many cases, thermoplastics can meet the strength requirements of such tools, but they cannot meet the rigidity requirements when performing test tasks. This is where carbon fiber composites play a role. Carbon fiber composite has high hardness and excellent performance in chemical resistance, wear resistance and impact resistance. At the same time, it also has good durability and toughness, so it is very suitable for functional components with high strength requirements of 3D printing tools. Thus, it becomes a reality that plastic parts replace metal parts.
Low density and high strength: carbon fiber material is characterized by light weight and high strength. Most people realize that carbon fiber also has these advantages. The density of carbon fiber material is 1.7g/cm2, and the density of common structural materials aluminum and steel are 2.7g/cm2 and 7.85g/cm2 respectively. The weight reduction characteristics of carbon fiber are more prominent, and its mechanical properties are also very excellent, Generally, the tensile strength of carbon fiber can reach 3500MPa, which is several times that of steel. The comprehensive strength is the most prominent in the existing structural materials.
High temperature resistance: the working temperature of carbon fiber can reach 150 ℃ - 180 ℃, and the thermal expansion coefficient of carbon fiber material is relatively small. It will not deform with the working temperature, and can well ensure the dimensional stability of products, especially for industrial users.
Corrosion resistance and anti-aging: the biggest difference between carbon fiber and metal materials is that carbon fiber belongs to a non-metallic material. Its electrochemical property is low. The effect of acid and alkali corrosion on carbon fiber is very low. 3D printed carbon fiber products can adapt to all kinds of complicated environments and extend the service life of products.
