How strong is carbon fiber composite?

How strong is carbon fiber composite? In recent years, carbon fiber composites must be widely known. The shadow of carbon fiber composite is all over every science fiction film and racing movie. In real life, carbon fiber composites are also widely used in aerospace, cars, urban rail, sporting goods and other work. How did carbon fiber composite become a popular raw material? What are its advantages? Carbon fiber composite has strong physical properties. Its specific strength and specific strain rate are many times higher than those of other aerospace aluminum alloys. In other words, under the same compressive strength and rashen strain rate, the net importance of carbon fiber products is far less than that of metal products when considering the property rules of products. Carbon fiber composites This benefit can be transformed into a significant practical effect of fat reduction, which can expand the airport's cargo capacity, increase the number of flights and save resources. It should be understood that the use value of one gram of weight released on an aircraft is much higher than that of one gram of gold. Authoritative experts in the industry emphasize that every 1kg reduction in the weight of the airport itself is equivalent to an economic gain of five million US dollars. Carbon fiber composites Carbon fiber composites are more reliable. The reliability of carbon fiber composites is reflected in corrosion resistance and fatigue relief. When you fly outside an airport, you often have to come in the wind and go in the rain. It's inevitable to get in the sun and rain. Sulfate in the air and various kinds of strong acid and alkali chemicals in the precipitation will constantly corrode the surface of t

Manufacturing process of carbon fiber car accessories and its advantages to car manufacturing

Manufacturing process of carbon fiber car accessories and its advantages to car manufacturing Carbon fiber car accessories are generally manufactured by molding, vacuum introduction, autoclave and other processes. What advantages can carbon fiber car accessories bring to car making? I'll give you an introduction today. 1. Improve the level of body development Because carbon fiber composite has stronger plannability than metal, it is easier to channel, modularize and integrate the body development. In this way, the hybrid body structure of carbon fiber body and metal channel can achieve modularization and integration for the traditional car body structure, greatly reduce the types of parts, reduce tooling investment and shorten the development cycle. 2. Lightweight After the application of carbon fiber in car, the remarkable benefit to car manufacturing is the lightweight of car, which directly affects the improvement of energy saving, acceleration and braking function. Generally speaking, the vehicle weight is reduced by 10%, the fuel consumption is reduced by 6% ~ 8%, the emission is reduced by 5 ~ 6%, the 0-100km / h acceleration is increased by 8 ~ 10%, and the braking distance is shortened by 2 ~ 7m. 3. Security Lightweight body can make the center of gravity of the whole car move down, improve the operation stability of the car, the operation of the vehicle will be more safe and stable. Carbon fiber composite material has excellent energy absorption rate. The energy absorption ability is six to seven times that of steel and three to four times th

Advantages of carbon fiber car accessories

Advantages of carbon fiber car accessories 1. Drive shaft application. The stress situation of car transmission shaft is relatively complex. If we want to accept a large torque, we should fully consider the characteristics of carbon fiber composite material, such as anisotropy, high specific strength and relatively low specific modulus. Then, carbon fiber composite material transmission shaft can replace metal products to meet the application requirements. The carbon fiber transmission shaft can not only reduce the weight by 60%, but also has better fatigue resistance and durability. 2. The use of body and chassis. Because carbon fiber itself has enough strength and stiffness, it is the main structural parts of car body and chassis. By using this data, the weight of the car body and chassis can be reduced by 40% - 60%, which is equivalent to one third to one sixth of the weight of the steel structure. Now many racing car bodies and some modified car bodies use this kind of information. 3. The application of brake pads and the environmental protection and wear-resistant characteristics of carbon fiber car accessories are very suitable for brake pads. However, the price of this kind of products is relatively high, and they are generally used in high-end brand cars. The general brake disc will become red due to absorbing a lot of heat energy, and the carbon fiber brake disc can accept the high temperature of 2500 ℃, and has excellent braking stability, which greatly increases the driving safety. The purpose of using carbon fiber car parts and carbon fiber motorcycle parts

Application advantages of carbon fiber battery box in new energy vehicles

Application advantages of carbon fiber battery box in new energy vehicles The breakthrough of electric vehicles. In addition to improving the infrastructure of charging stations, there is still room for improvement in the scale and planning of electric vehicles. Battery and its shell is a crucial skill element. Carbon fiber battery box can reduce weight, improve stiffness and temperature management: there are many advantages in using carbon fiber composite materials in the battery shell of electric vehicles. Carbon fiber reinforced plastic (CFRP) makes the battery box particularly light, stable and safe. The traditional battery shell for electric vehicles is mainly made of aluminum and steel. The lightweight structure of carbon fiber materials has many advantages for gasoline power and electric vehicles. It's light weight, especially conducive to battery life. Carbon fiber battery box is mainly made of carbon fiber composite materials and some aluminum parts. The characteristics of the enclosure depend primarily on the planning of the base plate and cover plate: in general, the special core material is surrounded by multiple layers of carbon fiber and epoxy resin. It is also possible to have a hybrid variant of carbon fiber and glass fiber. The base protects the battery from impact from below, as well as from obstacles and other vehicles. In addition to its light weight, the data also has many advantages: the stiffness of the battery shell can be compared with that of aluminum structure, but the data used is much less, and the thermal conductivity is about 200 times that of aluminum. The carbon fiber composite data can better protect the battery from the influence of cold and heat. In addition, the composite data also has the best value for t

The working principle of automobile tail is the same as that of airplane wing

The working principle of automobile tail is the same as that of airplane wing The tail wing of the car originated from the racing car first. At that time, the main effect of the car was to provide the car with pressure, enhance the grip of the tire, and make the car move smoothly and bend in the process. The basic principle of the spoiler used in racing cars is the same as that of the aircraft wing, and it was later transplanted to the ordinary car. The wings of the aircraft are only to produce upward lift forces, while the spoiler wings of racing cars produce downward suppression. When air flows through the wing, because the air flow velocity over the wing is faster and the lower air velocity is slow, the air pressure above the wing surface decreases, and the air pressure below the relative wing surface is larger, so the upward lifting force is generated, and the faster the speed is, the greater the pressure difference. If the wing is reversed, it is a simple racing spoiler, and the effect is the opposite. It produces downward pressure, which is usually called downforce. Aircraft wing When the car is moving at high speed, according to the aerodynamics principle, we know that air resistance will be encountered during the course of the car moving. The aerodynamic force in the longitudinal, lateral and vertical directions will be generated around the center of gravity of the car, among which the longitudinal direction is air resistance. In order to effectively reduce and overcome the influence of the space-time air resistance of the high-speed car, people designed and used the tail wing of the car, which is to make the air produce the fourth effect force on the car, that is, to produce a larger adhesion to the ground, which can offset some lift forces, and can cont

Do you know how to distinguish true and false carbon fiber?

Do you know how to distinguish true and false carbon fiber? Carbon fiber is a very popular new material in the market at present, because it has high strength, light weight, high temperature resistance, low temperature resistance, creep resistance, corrosion resistance and so on. The route of modern carbon fiber industrialization is precursor fiber carbonization process. The composition and carbon content of three kinds of raw fiber are shown in the table. At present, it has been used in medical equipment, automobile manufacturing, sporting goods, military and other places. With the increasing popularity, there are many fake carbon fiber products in the market. Here are some ways to distinguish between real and fake carbon fiber 1. Handle. The real carbon fiber has obvious fiber feeling when touching, while the fake one just feels very smooth, so there is a big difference when touching with hands. 2. The weight of real carbon fiber is very light, only 1 / 4 of that of steel in the same volume, while the weight of fake carbon fiber will not be so light 3. Because fake carbon fiber is generally produced by plasticizing materials, it will gradually melt when meeting fire, while real carbon fiber can withstand high temperature, so it can withstand general flame temperature 4. The molecular structure of carbon fiber is hexagonal honeycomb. If it is impacted by external force, it will be broken like glass instead of deformed like steel
