The automobile exhaust pipe made of carbon fiber does not need to be preprocessed in the manufacturing process, the working procedure is convenient, plates are allowed to be intersected, the exhaust pipe resists acid, alkali, salt and corrosion of atmospheric environment and does not need to be maintained periodically, by additionally forming the inclination hole in the bottom of the exhaust pipe, when an automobile stops traveling and is parked, if it is short-distance traveling, when condensate water generated by the exhaust pipe is not evaporated fully and remains in the exhaust pipe, the condensate water directly flows out from the inclination hole in the exhaust pipe and does not accumulate in the exhaust pipe, and the situation that acid generated by combination of the condensate water in the exhaust pipe and gas such as sulfur dioxide and nitrogen dioxide in waste gas of the automobile corrodes the exhaust pipe, and the exhaust pipe rusts easily and is damaged can be reduced.
Description
Technical field
The present invention relates to automotive field, specifically a kind of carbon fiber automobile exhaust pipe and processing technology thereof.
Background technology
The energy and environment are the two large problems of 21 century facing mankind.Along with the development of economic society, the mankind are increasing to the demand of the energy.According to estimates, to the year two thousand fifty mankind, the demand of the energy can be reached present twice, then can reach present three times to the end of this century.Reserves are limited on the one hand for traditional fossil energy, it is impossible to meet the demand of social development, and consuming excessively of fossil energy brings serious environmental problem on the other hand.In order to solve a dual difficult problem for energy shortage and environmental pollution, the exploitation of reproducible clean energy resource is most important.
Carbon fiber, as the composite of a kind of advanced person, is widely applied at multiple fields such as Aero-Space, nuclear energy equipment, transportation and stealthy weapons.Carbon fiber has many premium properties, the axial strength of carbon fiber and modulus are high, density is low, higher than performance, without creep, superhigh temperature resistant under non-oxidizing atmosphere, fatigue durability is good, specific heat and electric conductivity are between nonmetal and metal, thermal coefficient of expansion is little and has anisotropy, good corrosion resistance, X-ray transparent is good, good electrical and thermal conductivity performance, electromagnetic wave shielding is good, there is high specific strength and specific modulus, low thermal coefficient of expansion, high temperature resistant, corrosion-resistant, the performance of a series of excellence such as creep resistant and self-lubricating, the features such as flexibility and the stitchability also with fiber.For strengthening the process based prediction model of carbon fiber further, it will usually by the sheet material of carbon fiber and other material or Material cladding, thus reaching to strengthen the purpose of performance.The demand of carbon fiber is increased by modern industry further, higher requirement that its performance has also been deducted a percentage.But existing carbon fiber complex manufacturing, quality are expensive by raw material restriction, high-quality carbon fiber material, thus limit the further development of carbon fiber.The research and development of novel carbon fiber is imperative.
Development along with China's economy, it is very universal that motor vehicles becomes, present each family nearly all has an automobile, people are when selecting automobile, not only focus on the appearance of automobile, safety and stability and environmental consciousness to automobile are also extremely valued, in recent years, urban motor vehicle increases quickly, incident traffic noise pollution environmental phenomenon also becomes increasingly conspicuous, the harm that environmental protection is maximum is noise pollution by automobile, the motor vehicles such as automobile are in use, exhaustor is the parts damaged that get rusty easily, particularly those automobiles mainly travelled in city short distance, exhaustor get rusty damage phenomenon more prominent.Study by analysis, find that exhaustor is easiest to the major reason damaged of getting rusty, except the material with exhaustor that is commonly understood by is relevant, when another major reason is because each running car, owing to just starting working, whole section of exhaustor or temperature are relatively low, and the damp and hot waste gas that electromotor ejects is through colder exhaustor, and the acoustic filter position particularly exhaustor in exhaustor is met cold and produced condensed water.If running car time long enough, then exhaustor slowly heating under the heating of waste gas, produced condensed water can be heated and evaporate, if but automobile is to do short distance to travel in city, long just end travels and flame-out parking running time, then exhaustor does not also reach enough temperature, produced condensed water also just remains in but without being evaporated in exhaustor particularly acoustic filter, and the gases such as water sulfur dioxide in automobile exhaust gas, nitrogen dioxide can produce acid after being combined, corrode exhaustor and make its damage that gets rusty easily.
