What is the carbon fiber? Do you want to know more?

Carbon fiber is a high-strength and high-modulus fiber with a carbon content of more than 90%, and a continuous fiber material composed of stable continuous carbon molecules in a layered structure. It is made of acrylic fiber and viscose fiber by high temperature oxidation and carbonization.

A carbon fiber with a thickness of 1/10 of a human hair can have a tensile strength of 7-9 times that of steel, and its specific gravity is only 1/4 of that of steel.
The carbon fiber production process is divided into four steps: polymerization, spinning, pre-oxidation, and carbonization. The downstream application of carbon fiber requires not only composite materials, but also weaving, prepreg, winding, pultrusion, molding, RTM (resin transfer molding), autoclave and other processes. , carbon-based, ceramic-based, metal-based.

1. Carbon fiber specifications
1k, 3k, 6k, 12k and 24k large tow carbon fiber cloth, 1k refers to 1000 carbon fiber weaving.

2. Tensile modulus of carbon fiber Tensile modulus refers to the weight per square meter that the fiber can bear before breaking, reflecting a level of rigidity and the degree to which the fiber stretches under a certain pressure. Modulus scale IM6/IM7/IM8, the higher the number, the higher the modulus and the harder the material. There are many grades of carbon fiber, high modulus grade, medium modulus high strength grade, high modulus high strength grade, diameter 0.008mm to 0.01mm, tensile strength 1.72Gpa to 3.1Gpa, and modulus from 200Gpa to 600Gpa. The higher the strength, the more continuous the pull; the lower the strength, the more it will break;
