Carbon fiber automobile exhaust pipe, which includes: carbon fiber exhaust pipe body, inclined hole, and heat dissipation layer. Automobile exhaust pipe made of carbon fiber is not pre-processed in production, convenient in the process, the plate is allowed to cross, acid, alkali, salt and atmosphere Corrosion of the environment. Without regular maintenance, by adding a slanting hole at the bottom of the exhaust pipe, when the car is stopped at the end of the drive. If it is short-distance driving, the condensed water generated by the exhaust pipe has not been fully evaporated and remains in the exhaust. In the tube, the condensate will flow directly from the inclined hole in the exhaust pipe. And will not accumulate in the exhaust pipe, reducing the condensation water in the exhaust pipe and the sulfur dioxide, nitrogen dioxide and other gases in the exhaust gas of the automobile. The acid produced erodes the exhaust pipe to make it susceptible to rust and damage.

Energy and the environment are two major problems facing humanity in the 21st century. With the continuous development of the economy and society, human demand for energy is increasing. It is estimated that by 2050 humans will have twice the demand for energy, and by the end of the century it will triple. On the one hand, traditional fossil energy sources have limited reserves and cannot meet the needs of social development. On the other hand, the excessive consumption of fossil energy has brought serious environmental problems. In order to solve the dual problems of energy shortage and environmental pollution, the development of renewable clean energy is crucial.

[0003] As an advanced composite material, carbon fiber has been widely used in aerospace, nuclear energy equipment, transportation, and stealth weapons. Carbon fiber has many excellent properties. Carbon fiber has high axial strength and modulus, low density, high specific performance, no creep, high-temperature resistance in a non-oxidizing environment, good fatigue resistance, specific heat and conductivity between non-metal and Between metals. The coefficient of thermal expansion is small and anisotropic, corrosion resistance is good, X-ray permeability is good, good electrical and thermal conductivity, good electromagnetic shielding, high specific strength, and specific modulus. Low thermal expansion coefficient, resistance A series of excellent properties such as high temperature, corrosion resistance, creep resistance and self-lubrication, as well as fiber flexibility and braid ability. In order to further enhance the physical and chemical properties of carbon fiber, carbon fiber is usually combined with other materials or materials to achieve enhanced performance. The demand for carbon fiber in the modern industry has further increased, and its performance has also been raised. However, the current carbon fiber production process is complex. The quality is restricted by raw materials, and the high-quality carbon fiber raw materials are expensive. Thus limiting the further development of carbon fiber. Research and development of new carbon fibers are imperative.

With the continuous development of China’s economy, motor vehicles have become very popular. Nowadays, almost every family owns a car. When people choose cars, they not only pay attention to the appearance of the car. But also attach great importance to the safety and stability of the car and environmental awareness. In recent years, urban motor vehicles have grown rapidly, and the traffic noise and environmental pollution phenomena have become increasingly prominent. The biggest hazard to the environment is noise pollution. When the motor vehicles are used, the exhaust pipe is easy to rust. Damaged parts, especially those that travel mainly in the city, have more pronounced rust damage to the exhaust pipe. After analysis and research, it is found that the exhaust pipe is the most susceptible to rust damage. In addition to the general understanding of the material of the exhaust pipe, another important reason is that each time the car is running. Due to the beginning of work, the entire section. The exhaust pipe is still at a lower temperature. And the hot and humid exhaust gas discharged from the engine passes through the cooler exhaust pipe. And condensed water is generated in the exhaust pipe, particularly the muffler portion of the exhaust pipe. If the driving time of the car is long enough, the exhaust pipe will slowly heat up under the heating of the exhaust gas. And the generated condensed water will be heated and evaporated. But if the car is short-distance driving in the city, the driving time is not long and the driving is ended. When the fire is stopped, the exhaust pipe will not reach sufficient temperature. And the condensed water generated will not be evaporated and remain in the exhaust pipe. Especially the muffler, and the sulfur dioxide and nitrogen dioxide in the water and automobile exhaust gas. When the gas is combined, it will produce acid. It will erode the exhaust pipe and make it easy to rust and damage.
