Driven by new technologies, there are also high requirements for the performance of materials. At this time, high-performance materials will be used to replace today’s traditional metal products. Of course, some people who do not know this material very well will use carbon fiber. The material is compared with glass fiber and aluminum alloy materials, so this article will talk about the comparison of these three materials.
Carbon fiber material vs glass fiber
From the perspective of the material, it can be found that carbon fiber is a high-performance fiber material containing 90% carbon stars. Now it is commonly used to extract carbon fiber from polyacrylonitrile, or from viscose fiber or pitch fiber, which is oxidized and carbonized at high temperature. production. It is said that the density of fiber material is only 1.5g/cm3, so the quality of carbon fiber products will be very light. Then carbon fiber products can be mixed with metal, ceramic, resin and other matrices to make carbon fiber composite materials. Glass fiber cone is an inorganic material with excellent performance. There are many kinds of non-metallic materials, which are made of seven kinds of ores, including E stone, quartz sand, limestone, dolomite, boronite, and boronite, through high-temperature melting, wire drawing, winding, and weaving.
From the perspective of performance, carbon fiber materials have a small specific gravity, and the comprehensive indicators of specific strength and specific modulus are superior to existing structural materials. They can withstand ultra-high temperatures in non-oxidizing environments, and have good fatigue properties. The specific heat and electrical conductivity are between non-metals and metals. It has good X-ray permeability and can be used in medical fields. It has good corrosion resistance, is insoluble and non-swelling in organic solvents, acids, and solvents, and has outstanding corrosion resistance. Glass fiber is an inorganic fiber, non-flammable, good insulation, good chemical resistance, high modulus of elasticity, good rigidity, low water absorption, although the price is lower than carbon fiber, but the overall performance is not as good as carbon fiber.
Comparison of carbon fiber material and aluminum alloy material
The quality of carbon fiber composites is lighter. The density of carbon fiber composites is 1.7g/cm3, while the density of aluminum alloy is about 2.7g/cm3, which makes the weight reduction effect of carbon fiber composites better.
The compressive strength of the carbon fiber composite material in the cross section reaches 20G, while the strength of our aluminum alloy can only reach 70g, which means that the carbon fiber is far ahead of the aluminum alloy in terms of strength, and its strength is much higher than that of the aluminum alloy. This is why carbon fiber composites stand out among many structural materials. The bending resistance of carbon fiber is much higher than that of metal materials.
During the welding process of aluminum alloy, it is easy to form plastic materials, and carbon fiber composite materials have higher performance in processing, because carbon fibers have both the softness and processability of textile fibers before forming, so the design process Among them, the design performance is better, and the corrosion resistance performance in some special environments is also better.
In this way, it can be seen that it is not unreasonable for carbon fiber materials to become black gold in the material industry, but it does not mean that carbon fibers are used everywhere, and more depends on demand. For example, glass fiber is definitely better for electronic insulation. If you need carbon fiber products, welcome to consult the editor of New Materials.
