What is the material of F 1 racing car?
It looks fragile, but it is graphitized, in fact, to better protect drivers. F 1 Racing materials are mainly carbon fiber materials. The biggest disadvantage of carbon fiber is that it is expensive. So apart from aerospace, the rest are basically F 1 racing cars.

After the mold was born, it was time to build it by hand. Skilled technicians stick carbon fiber layer by layer on the mold. Because of different pressures in different parts of the car body, the number of carbon fiber layers stuck is different and the arrangement direction is different. The arrangement direction of each layer of carbon fiber determines which direction the body will disperse under pressure. Therefore, this process needs to be carried out carefully, and hair dryers and scalpels will come in handy at this time. The average number of carbon fiber layers in F 1 racing car is 12, and the aluminum alloy with honeycomb structure is laid in the most central part.

After the time-consuming carbon fiber laying work is finished, the last step is to send the car body into a special oven with high temperature and high pressure, so that each layer of carbon fiber can be tightly bonded. This process has to be repeated three times before the car body is complete. It takes six weeks to bake the first car body, but after the first car body is made, the subsequent car bodies can leave the factory in only one week.

Study on preparation of high performance carbon fiber and other carbon materials

The research and development of various carbon materials is the research on the process, microstructure and mechanical properties of carbon fibers invested in the special research plan of National Science Council. Gradually develop and derive research on various carbon materials. The projects are as follows:

1. Research and development of high strength carbon fiber

At present, the research and process development of carbon fiber are divided into two systems, which are based on polyacrylonitrile fiber and asphalt fiber. In the polyacrylonitrile-based carbon fiber system, high-performance carbon fiber was developed from polyacrylonitrile fiber, and the effects of various manufacturing parameters on the mechanical properties and surface properties of carbon fiber were studied. At present, the manufacturing technology of high strength carbon fiber, high coefficient carbon fiber and aviation grade carbon fiber can be controlled. In pitch carbon fiber, the emphasis is mainly on the purification of raw materials and the growth stage of mesophase, and it is hoped that high coefficient carbon fiber can be manufactured through the control of mesophase. The research on the growth factors of mesophase formation can be applied not only to carbon fibers, but also to carbon films and high-performance carbon electrodes, and more than 40 research papers have been published in this regard.

Second, the research and development of activated carbon fiber

Activated carbon fiber is mainly used for the purification of drinking water, the treatment of various wastewater and waste gas, and the decolorization and deodorization. Activated carbon fiber can be used as fiber, cloth, felt and various forms in practical application. The research of activated carbon fiber mainly comes from the research foundation of carbon fiber. Because PAN-based activated carbon fiber contains nitrogen, this element has a good adsorption effect on mercaptan, and it has the advantage of high strength compared with other raw materials. In this study, microporous and mesoporous activated carbon fibers are mainly prepared by process control, so the influence of process factors on the porosity and adsorption of fibers is biased in the research process. At present, industrial, military and medical grade activated carbon fibers with specific surface area exceeding 1000 m2/g have been prepared. At present, more than ten research papers and four patents have been published.

Third, the research and development of flame retardant fiber

PAN-based fireproof fiber can withstand 900℃, does not burn in flame, does not produce toxic gas, and is acid and alkali resistant, so it can be applied to various fireproof purposes, such as fireproof clothing, heat insulation materials, various building materials, decorative materials, etc. PAN-based flame retardant fiber can be said to be a by-product of studying carbon fiber, and the oxidized fiber produced by oxidation engineering, the intermediate process of manufacturing carbon fiber, is flame retardant. Therefore, how to improve its fire resistance at this stage without damaging its spinnability is inversely proportional. Therefore, how to reach a balance point is an important topic. In this study, the microstructure model of oxidized fiber was established by scanning electron microscope, transmission electron microscope and X-ray diffractometer. At the same time, a heating device was installed on the X-ray diffractometer to observe the microstructure changes of PAN fiber during the heating process and calculate its crystal dislocation activation energy. At present, the research results * * * have published more than ten related research papers and three patents.

Fourthly, the research and development of carbon/carbon composites.

At present, carbon/carbon composites are mainly used in various missile nozzles, aircraft brake pads, artificial bones and so on. The interfacial properties between fibers and matrix in carbon/carbon composites have always been a difficult problem, and the relationship between the types of reinforcing fibers and their surface properties and matrix is a hot research topic. Because carbon/carbon composites are expensive and can't be used in large quantities, efforts are being made to research and develop low-cost carbon/carbon composites in order to be applied to brake pads of various vehicles.

Research and Development of verb (abbreviation of verb) Conductive Carbon Film

Carbon thin film is an important material for secondary lithium batteries to become positive or negative electrodes. The type of carbon film determines the power, charging and discharging efficiency and life of secondary lithium batteries. In the early research, the carbon film made of PAN was used as the raw material to make a battery, and its capacity was tested by the Institute of Materials Science and Technology to be 250 mAh/g. Recently, a carbon electrode with a capacity of 500mAh/g was made by controlling the asphalt main phase. At present, the research focus is to understand the relationship between the arrangement, direction, microstructure, internal hole size and capacitance of carbon layer, and then to understand the relationship between charging and discharging efficiency and charging times. There is a patent at present.
