The key material for the "takeoff" of the low-altitude economy.

The low-altitude economy brings a new growth driver for carbon fiber.

Carbon fiber Composite Materials are the key materials for achieving lightweight in aerospace vehicles.

Carbon fiber is a fiber-reinforced material with more than 90% carbon content. It has many properties such as low density, high specific strength, and high specific modulus. Under the same weight, its tensile strength can be more than 9 times higher than that of steel, aluminum alloys, and titanium alloys, and its elastic modulus can be more than 4 times higher. These advantages make carbon fiber an ideal choice for lightweighting aerospace vehicles. By applying carbon fiber composite materials to the manufacturing of aircraft fuselage structures and internal components, the overall weight of the aircraft can be effectively reduced, energy consumption lowered, and the structural strength and safety enhanced. Using carbon fiber composites in the construction of eVTOLs can help reduce the overall weight of the aircraft by 30%-40%.

Carbon Fiber Composites: Different Applications Based on Matrix Materials

Carbon fiber composites refer to structural or functional materials made by combining carbon fibers as reinforcement with matrix materials such as resin, metal, ceramics, and rubber. Depending on the matrix material, carbon fiber composites can be classified into resin-based composites, metal-based composites, ceramic-based composites, and rubber-based composites. Resin-based composites are mainly used in fields such as construction, chemicals, transportation, medical, and aerospace; metal-based composites are primarily used in aerospace, aviation, automotive, and sports equipment; ceramic-based composites are mainly applied in high-temperature engine components; and rubber-based composites are used in pipes, wear-resistant liners, and special sealing parts.
