Specific strength and specific modulus of carbon fiber reinforced epoxy resin composite is the highest among existing structural materials. In areas with strict requirements on density, stiffness, weight and fatigue performance, carbon fiber composite materials are quite advantageous in occasions that require high temperature and high chemical stability.
The composite material is composed of carbon fiber and epoxy resin. It has become an advanced aerospace material due to its small specific gravity, good rigidity and high strength. For every 1 kg reduction in the weight of a space vehicle, the launch vehicle can be reduced by 500 kg. Therefore, advanced composite materials are widely used in the aerospace industry.
碳纤维及碳纤维复合材料的优点 Advantages of carbon fibers and carbon-fiber composite materials
High strength (5 times of steel)
Heat resistant (can withstand high temperatures above 2000°C)
Excellent thermal shock resistance
Low thermal expansion coefficient
Small heat capacity
Small specific gravity (1/5 of steel)
Excellent anti-corrosion and anti-radiation performance
Carbon fiber winding is a continuous molding method of composite materials, which is to wind continuous fibers or fabrics impregnated with resin glue on a core mold according to a certain rule, and then solidify and demold into composite products.
Applicable products: carbon fiber and glass fiber composite products, such as circular pipes, pressure tanks, storage tanks and other rotationally symmetric products (reactors, large electronic stators, high-pressure gas cylinders, various insulating sleeves)
Features: Continuous molding process completed at one time; well guaranteed shape and size of the finished product, and high strength in diameter direction. However, relatively high production cost, specialized winding machines and auxiliary equipment are required.
Process classification (by different resin molding states)
Among all the processes, wet winding is the most common application. Dry winding is only applied in high-performance, high-precision and high-end aerospace technology.
