The application of carbon fiber composite materials in the automotive field is mainly in automotive brake pads, automobile transmission shafts, buffer, body, car interior, and engine parts, which can effectively reduce automotive self -weight and improve car performance. 1. The cost is too high
Compared with the titanium alloy, the price of car carbon fiber composite materials is more than the price. Several times, and the price of large -sized carbon fiber vehicle components even exceeds 10,000 yuan. This is mainly because the production process of some carbon fiber components requires a lot of handicrafts, and the scrap rate is very high, causing a large increase in costs.
2, the deformation is almost impossible to repair
This is also an important factor that the carbon fiber single body case cannot be spread on a large scale. Because carbon fiber composite materials do not have the ductility of metal materials, once the deformation caused by external forces appears, it means that the carbon fiber inside the carbon fiber single -body body has a break or inter -layer resin. The broken carbon fiber and the decayed resin cannot be connected anyway, so the carbon fiber single -body shell body can only be scrapped. In contrast, the crack can be repaired with several layers of carbon fiber. 3, carbon fiber single -body shell body structure design is complicated
Generally speaking, the framework body only needs to be structural design on the whole body, because metal materials have various same sexuals with various same sexuals Material characteristics. As the name suggests, the meaning of the same sex means that the nature of the physical and chemistry inside the object will not change due to different directions, that is, the performance value measured by a certain object in different directions is exactly the same. For example, the same steel plate is the same everywhere. Then in the design process, metal materials only need to consider one direction. Judging from the commonly used Yang’s modulus, pine ratio, shear modulus and other parameters, you only need to use it once to complete the calculation. However, carbon fiber composite materials are not the case. The characteristics of carbon fiber composite materials are the opposite sex.
4, the life of carbon fiber materials is short
of course, the carbon fiber itself is no problem. The problem is to be used as a composite material substrate resin. The durability of the resin is weaker than the metal. Light aging, high and low temperature, acid and alkalinity will accelerate its aging process, and then cause problems such as yellowing, cracking, and brittleness. This principle is the same as the aging of ordinary plastic parts we will always encounter.
Building reinforcement carbon fiber enhancement now many projects are used in many places to enhance carbon fiber enhancement. Many people do not know what or what they can use. Obviously, products are usually classified, carbon fiber, carbon fiber circuit boards, all compare For commonly used soundplay equipment, carbon fiber enhances more practicality. Where can I see a little, if you understand. The reinforcement of houses can be used in two levels. One is the maintenance of the house damage; the other is to enable the house to achieve certain resistance, such as anti -earthquake capacity, and reinforcement. A tendon reinforcement is a simple and effective connection and anchor technology for the concrete structure; it can be implanted with ordinary steel bars and bolts can be implanted; it is now widely used in the reinforcement project of the building. House detection and use of certain technical means and methods, check and determine its structural quality, and implement dynamic monitoring. House testing, also known as house quality testing and evaluation, refers the process of.
The projects of the previous century, euphemistically, is a relatively backward project. First of all, they are always advancing with the times, and many things cannot keep up with the times. Over time, many unfavorable factors will naturally appear. In this regard, this is a remedy project, which is to make the relatively backward things more popular, but the cost of the project cannot be changed. The total cost is still so high.
Nowadays, many residents living in old residential buildings are also facing the same concerns, that is, the buildings they live in different degrees of safety problems because of their age. The wall cracks and the stairs are broken. But the most important problem is the safety of the floor. If the floor is not stable enough, the residents will worry about every day. If this problem cannot be resolved, it will seriously affect the quality of life of residents. Therefore, for many old residential buildings, it is a top priority to strengthen the floor. This is a matter of people’s livelihood that a urban management department is very concerned about. At the same time, the company has been committed to solving this problem. After long -term experimental and accumulated experience, the floor reinforcement technology has been quite mature. Through practice, the company’s Dechida carbon fiber cloth ground reinforcement construction has achieved good results, which can effectively ensure the safety of residential buildings.
Because many people now live in the old buildings, excluding some residents who have always lived in such a house, some people need to buy a second -hand house because of the lack of economy, or the old house is a school district. You must know that most second -hand houses are relatively long, not only the aging of various facilities, but also the safety of buildings is also worrying. In use, such buildings are difficult to ensure the safety of residents. Based on the principle of stifling hidden dangers in the cradle, strengthening the emergence of reinforced carbon fiber flooring, effectively lifting the residents’ concerns about safety. The test shows that the reinforcement of the floor of the floor with carbon fiber cloth new materials not only has obvious reinforcement effects, but also greatly improves the impact ability and shear strength of the entire building.
The reinforcement of carbon fiber cloth with good effects, many companies have begun to get involved in this industry, but the company’s strength can be described as good or bad to ensure the effect of enhanced the floor. You should choose reputation and powerful of.
Carbon fiber is one of the three high -performance fibers in the world today. His intensity is nine times that of steel, and the weight is only a quarter of steel. High temperature, radiation, far -infrared heating principle, heat stability (not hot -expansion and contraction), extremely superior characteristics such as harmless to organisms, are widely used in aerospace industry. The first batch of carbon fiber fishing rods in 1972 marked that carbon fiber gradually moved towards civilian use. Carbon Fiber (CF) is a new type of fiber material with high -intensity and high -profile fibers with a carbon content of more than 95%. It is a micro -graphite material obtained from organic fibers such as sheet -like graphite microcrystalline in the direction of fiber axis direction, carbonized and graphitized treatment. The carbon fiber is “soft and rigid”, the quality is lighter than the metal aluminum, but the strength is higher than that of steel. It has the characteristics of corrosion resistance and high modular amount. It is an important material in national defense military industry and civilian use. The carbon fiber enhanced plastic is mainly used for the aviation and aerospace industry; it can also be used for sports equipment, such as tennis rackets, skiing boards, racing, rowing, etc. Axis and so on. advantages: 1, high strength, higher strength, high mode volume 2, light light, corrosion resistance, fatigue resistance 3, small thermal expansion coefficient, low friction coefficient, high and low temperature r r r r r r r r r r r r Disadvantages: 1. Although the carbon fiber composite material is strong, the cutting strength is weak, and complex stress calculations are required during processing. 2. It will gradually turn white when it is placed in the sun. 3. The shielding rate is poor. The materials in the materials for material asking materials have a lot of carbon fiber related products, you can learn about it
Carbon fiber is a new material with excellent mechanical properties. Its proportion is less than 1/4 of the steel. The tensile strength of carbon fiber resin composite materials is generally above 3500MPa, which is 7-9 times steel, and the amount of anti -tensile elastic modulus is 230 ~ 430GPa is also higher than steel. Therefore, the ratio of the intensity of the CFRP, the intensity of the material, can reach 2000MPA/(G/CM3), while the ratio of A3 steel is only about 59MPa/(G/CM3), and its comparison is higher than the steel. The higher the material than the intensity, the smaller the component’s self -weight and the higher the modular amount, the greater the rigidity of the component. In this sense, the broad application prospect of carbon fiber in engineering has been foreshadowed.
