With the rapid growth of aerospace, automobile industry, aircraft manufacturing, wind power generation, 3C electronic products and other industries, as well as the steady development of sports and leisure, the growth of carbon fiber market demand will be more significant. Today, we will study the application of carbon fiber in 3C electronic products such as pen and electric appliances. According to foreign media reports, German electronics manufacturer carbon mobile is about to release the world's first carbon fiber case mobile phone carbon 1 Mk II. The device has been on pre-sale for 799 euros (about 6247 RMB) recently.
Carbon 1 Mk II is made of carbon fiber single shell. As a result, the phone is lighter, weighs 125g and is 6.3mm thick. It is worth mentioning that carbon fiber materials will block electromagnetic waves, so the manufacturer has developed a "composite material with radio function", which finally solves this obstacle. It took the manufacturer four years to develop this technology, which features a combination of high-quality carbon fiber / composite materials to make radio waves accessible. It is worth mentioning that every carbon mobile phone can be disassembled and returned to raw materials when it is not needed. On February 18, VAIO released the world's first three-dimensional molding carbon fiber body notebook computer, the new VAIO? Z. the four components of the pen motor shell are made of three-dimensional molding continuous carbon fiber material. The weight is as low as 958g, and it can also withstand a height drop of 127cm, giving consideration to rigidity and lightweight. At present, Dell, Lenovo ThinkPad and other brands use carbon fiber as the shell material of the pen. For example, the dellxps series uses all carbon fiber plate with 3K texture, reflecting the texture and texture of carbon fiber. Thinkpadx series adopts sandwich structure of carbon fiber sheet, and its appearance is UD pattern + spraying
Carbon fiber reinforced polymer (CFRP) is used as the material of notebook shell. It not only has the strong property of aluminum magnesium alloy, but also has the high plasticity of ABS engineering plastics. Its appearance is similar to plastics, but its strength and thermal conductivity are better than ordinary ABS plastics. Moreover, carbon fiber is a kind of conductive material, which can play a shielding role similar to metal (ABS shell needs another layer of metal film to shield), As a new type of high performance, environmental protection and recyclable material, CFRP has good thermal conductivity, shielding property, weather resistance and corrosion resistance. Carbon fiber composite materials are further compounded with carbon fiber and resin to obtain superior performance products. Carbon fiber is composed of long-chain carbon atoms bonded together, which is hard and light. Carbon fiber board, also known as carbon fiber composite board, is a kind of reinforced resin composite material. Its density is only 1.5g/cm3 and tensile strength is more than 1500MPa. It is made by laminating and hot pressing carbon fiber prepreg. Carbon fiber board generally has three kinds of texture: twill, plain and unidirectional.
Development trend: the advantages of carbon fiber composite in the application of pen shell are very prominent, mainly based on the characteristics of light weight and strong structure of carbon fiber composite, which can meet the development trend of small, light and portable. With the arrival of 5g, the heat dissipation of internal devices of notebook computer is the key, and the carbon fiber composite has strong thermal conductivity and natural material advantages. With the development of research, the development trend of carbon fiber composite is more and more obvious In addition, there will be more applications. However, due to the cost, process difficulty and single coloring of carbon fiber, it is only used for high-end products. It is believed that with the decline of carbon fiber price and the improvement of process and yield, carbon fiber composites will be more and more widely used in pen and TV.
