Carbon fiber, we have heard that it is a familiar and unfamiliar high-performance material for us. It has both the inherent properties of carbon material and the soft processing characteristics of textile fibers. It is called the king of materials.

Carbon fiber, for us, is a high-performance material that is both familiar and unfamiliar. It has both the inherent properties of carbon materials and the soft processing characteristics of textile fibers. It is called the king of materials.

The carbon fiber and the matrix material of the reinforcing material constitute a carbon fiber composite material. Carbon fiber is used in automotive frames, seats, cabin covers, drive shafts, rearview mirrors, etc., and automotive carbon fiber has several advantages:

Lightweight: At present, the electric car that is very hot is limited by the short battery life of the battery technology and becomes a bottleneck restricting its development. It can only be solved from the replacement of the body structure and materials. The carbon fiber composite material is 3/4 lighter than steel and 1/3 lighter than aluminum. The most direct impact is long cruising range and more energy saving.

Comfort: The soft tensile properties of carbon fiber improve the noise and vibration control of the vehicle, which will greatly enhance the comfort of the car.

Reliability: Carbon fiber has higher fatigue strength and good collision energy absorption. It can reduce the weight of the vehicle while maintaining strength and safety, and reduces the safety risk factor brought by lightweight.

Improve life: Some parts of the car require corrosion resistance, and must pass the test of high temperature, low cold and smoke. Ordinary metal parts can not guarantee the service life under different environments. Carbon fiber does not have corrosion and rust problems, which enhances the service life of automotive parts.

Carbon fiber manufacturing process

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 fiber shape, and the heat is in a stable state. Carbonization: heating 1 to 2 thousand degrees to drive away non-carbon atoms, and become black with high temperature oxidation, and then 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 heating resin is adsorbed on the fiber web and infiltrated by the extruded resin. Into the fiber mesh, the liquid resin is gelled after cooling.

When it comes to carbon fiber, I think it is sturdy, 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 temperature 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.
