Carbon fiber is a new type of fiber material with high strength and high modulus fiber with carbon content above 95%. It is a microcrystalline graphite material obtained by stacking organic fibers such as flake graphite crystallites along the axial direction of the fiber and carbonizing and graphitizing. Carbon fiber is “outer and softer”, its quality is lighter than that of metal aluminum, but its strength is higher than that of steel, and it has corrosion-resistant and high-modulus properties, and is an important material in defense military and civilian use. It not only has the inherent intrinsic properties of carbon materials, but also has the soft processability of textile fibers. It is a new generation of reinforcing fibers.
Due to the many advantages of carbon fiber, carbon fiber is mixed with other materials, and the application fields have become very extensive. It is used in fishing tackles, sports equipment, sporting goods, aerospace and other fields, and is used militaryly to manufacture rockets, missiles, satellites, radars, Important military products such as bulletproof cars and bulletproof vests; carbon fiber composite panels and carbon fiber sandwich panels are also widely used in the field of environmental protection.
The existing carbon fiber sandwich panel, the sandwich layer is usually made of foam filler or honeycomb filler, so that the sheet can not reduce the pressure and impact resistance while reducing the quality of the sheet, saving materials and reducing the production cost, with the economic society. With the rapid development, the application fields of carbon fiber sandwich panels continue to expand, especially in high-tech fields where ultra-rigid plates are required, such as aerospace model making, rocket launcher manufacturing, automotive parts, etc. The current sandwich panels do not reach this. Target requirements.
