Carbon fiber is a new type of high-strength, high-modulus fiber with a carbon content of more than 95%. It not only has the inherent characteristics of carbon material “hard”, but also has the “soft” processability of textile fiber, and is known as the king of new materials. In the future, with the substantial growth in demand from industries such as aerospace, automobile industry, aircraft manufacturing, wind power generation, and 3C electronics, as well as the steady development of sports and leisure, the growth rate of carbon fiber market demand will become more significant. This article introduces the application of carbon fiber in the housing of 3C electronic products such as laptops.
At present, brands such as Dell and Lenovo Thinkpad are using carbon fiber material as the material of the notebook shell. For example, the Dell XPS series uses a full carbon fiber sheet with a 3K texture, reflecting the texture and texture of carbon fiber. The Thinkpad X series adopts carbon fiber board with a sandwich structure, and its appearance is UD texture + spray coating. The above two brands occupy the main share of carbon fiber notebook computers. Other brands, such as HP, use continuous carbon fiber-reinforced thermoplastic sheets to avoid competition.
Using carbon fiber reinforced composite material (CFRP) as the material of the notebook shell, it not only has the elegant and strong characteristics of aluminum-magnesium alloy, but also has the high plasticity of ABS engineering plastic. Its appearance is similar to plastic, but its strength and thermal conductivity are better than ordinary ABS plastic. Carbon fiber is a kind of conductive material, which can play a shielding effect similar to metal (ABS shell needs another layer of metal film to shield). The following is a comparison table of typical structural material performance and weight reduction. It can be clearly seen from the table that CFRP The lightweight effect of carbon fiber is much higher than that of metal materials. Compared with steel, carbon fiber is 8 times stronger than steel, but its weight is only 70% of steel. Compared with aluminum, its strength is 20 times, but its weight is only 40% of aluminum. Lightweight, high strength, and high modulus, it is the material of choice for lightweight parts, so it is an ideal choice for notebook materials.
