What is the difference between glass fiber and carbon fiber?


The main difference between glass fiber and carbon fiber is that the chemical composition is completely different. The fiberglass is characterized by low price and low physical stability, but the carbon fiber has high price, but the physical stability is high, and the biggest feature is that the quality is light.fiberglass sealing rope

Glass fiber or fiberglass is an inorganic non-metallic material with excellent performance. It has many advantages, such as good insulation, heat resistance, good corrosion resistance and high mechanical strength. However, it is fragile and wear-resistant. Poor sex. The main components are silica, alumina, calcium oxide, boron oxide, magnesium oxide, sodium oxide, etc., according to the alkali content of the glass, can be divided into alkali-free glass fiber, medium alkali glass fiber and high alkali glass fiber. Glass fiber is commonly used as a reinforcing material in composite materials, electrical insulating materials and thermal insulation materials, circuit boards and other fields of the national economy.

Glass fiber can be divided into continuous fiber, fixed length fiber and glass wool according to its shape and length. According to glass composition, it can be divided into alkali-free, chemical-resistant, high-alkali, medium-alkali, high-strength, high-elasticity and alkali-resistant ( Alkali resistant) glass fiber, etc.

Carbon fiber is a new type of fiber material with high strength and high modulus fibers with a carbon content of over 95%. It is a microcrystalline graphite material obtained by stacking organic fibers such as flake graphite crystallites along the axial direction of the fiber and carbonizing and graphitizing. Carbon fiber is “outer and softer”, its quality is lighter than that of metal aluminum, but its strength is higher than that of steel, and it has corrosion-resistant and high-modulus properties, and is an important material in defense military and civilian use. It not only has the inherent intrinsic properties of carbon materials, but also has the soft processability of textile fibers. It is a new generation of reinforcing fibers.
