What is the manufacturing process of carbon fiber?

Drawing: heating the raw material, it is a reinforcing material: reinforcing material for winding forming, mainly various fiber yarns: such as alkali-free glass fiber yarn, medium alkali glass fiber yarn, carbon fiber yarn, high-strength glass fiber yarn, aramid fiber Yarn and surface felt, etc. Resin matrix, and various fillers. , extruded into a gel-shaped strand, the plastic fiber is composed of thousands of filaments.

Stable: After heating and oxidizing at 400 degrees, the thermoplastic macromolecule is converted into a heat resistant structure. It does not melt and incombust at high temperature, maintains the fiber shape, and the heat is in a stable state. Carbonization: heating 1 to 2 thousand degrees to drive away non-carbon atoms, become black with high temperature oxidation, and then combine with carbon atoms in the carbonization furnace. On the fiber.

Graphitization: Parallel filaments are subjected to a charged corrosion surface to better absorb the resin. The fiber web is composed of several hundred fibers. The resin coating and the fiber web enter the machine at the same time. The resin is adsorbed on the fiber web and infiltrated by the extruded resin. Into the fiber mesh, the liquid resin is gelled after cooling.

The principle is like sticking a piece of paper completely into a stack of thick paper piles, and the pile becomes solid.

When it comes to carbon fiber, I think it is strong, light and expensive (relative to steel and aluminum products), for example, used in high-end products such as F1 racing cars, but now in civilian cars, in fact, carbon fiber is a general term for materials, derived from There are many composite materials.

Different composite materials have different heat treatment temperatures depending on the carbonization rate, so the price between different carbon fiber materials will vary greatly. With the development of technology, the scope of application becomes larger, more capital is invested, and the recycling technology is mature, the cost of carbon fiber will further decline. Carbon fiber composites will be used more and more in automobiles.

Therefore, the application of carbon fiber in the automotive field will become more and more extensive. In the future, the emission of automobiles will become lower and lower, and the automobile itself will become more and more "high carbon". The two technologies that will subvert the car in the future are new carbon fiber materials that are intelligent.
