Carbon fiber and glass fiber are two kinds of reinforcing fibers commonly used in the composite family. Because their application fields and functions are similar, they are often compared. Most people know that the performance of carbon fiber is better than that of glass fiber, but the specific aspects are not very clear. Let's introduce the performance advantages of carbon fiber compared with glass fiber.

Although carbon fiber and glass fiber have high tensile strength as reinforcement materials, in this performance comparison, carbon fiber is much higher than glass fiber. Only some high-strength glass fibers can compare with the strength of conventional carbon fiber, but the cost is much higher.

In terms of weight, carbon fiber accounts for about 65% of the weight of glass fiber, with obvious advantages (the density of some models of carbon fiber is similar to that of glass fiber, but still lower than that of glass fiber).

In terms of temperature resistance, carbon fiber has great advantages over glass fiber. Glass fiber is easy to burn, and its performance will be greatly reduced after exceeding 300 ℃, while carbon fiber can maintain stable performance in thousands of degrees high temperature environment. Therefore, it is much better to use composite materials and choose carbon fiber in high temperature environment.

In the selection of composite matrix, the optional space of carbon fiber is much better than that of glass fiber. Carbon fiber can be used in combination with many types of materials such as metal, ceramics and resin, but glass fiber is only used in combination with resin materials. Moreover, due to the difference of strain, the bearing capacity of carbon fiber composites is far due to FRP.

In addition, carbon fiber has conductive properties and can be used to make conductive and heating materials, glass fiber insulation. The X-ray transmission performance of carbon fiber can be used in medical examination. Carbon fiber also has great advantages in material wear resistance
