What is the difference between carbon fibers and glass fibers?

What is the difference between carbon fibers and glass fibers?

Glass fiber is a kind of inorganic non-metallic material with excellent performance.

Carbon fiber is a new kind of high strength and high modulus fiber material with more than 95% carbon content.

What's the difference between the two?

Glass fibers are mainly composed of silica, alumina, calcium oxide, boron oxide, magnesium oxide, sodium oxide and so on. They are usually used as reinforcing materials in composites.

Carbon fiber is a kind of microcrystalline graphite material, which is made up of flake graphite microcrystalline and other organic fibers stacked along the direction of fibers. It has been used in many fields by carbonization and graphitization.

The advantages of glass fiber are good insulation, heat resistance, corrosion resistance and high mechanical strength, but glass fiber is brittle and wear resistance is poor.

As a new structural material, carbon fibers have many excellent properties, such as high axial strength and modulus, low density, only 1.7g/cm3, high temperature resistance, good fatigue resistance in non-oxidizing environment, small thermal expansion coefficient and stable size.

Carbon fiber is a kind of non-metallic material with excellent corrosion resistance and aging resistance. It has a long service life. Carbon fiber also has excellent X-ray transmission performance, and has a wide range of applications in the medical field.
