Advantages & Disadvantages of Carbon Fiber Composites
Advantages of carbon fiber composites
Compared with traditional metal materials, carbon fiber composites have high tensile strength, high modulus, low density, high specific strength and high specific modulus. Carbon fiber composites are light in weight, high in strength and high in toughness. Compared with plastic products, its strength is dozens of times stronger than them, so light weight and high strength is one of the remarkable features of carbon fiber rod composites .
2. Carbon fiber composites have good resistance to high and low temperatures, high thermal conductivity,
and the coefficient of linear expansion has a negative temperature along the fiber axis. The effect, that is,
with the rise in temperature, carbon fiber composites have a tendency to shrink, good dimensional stability, good fatigue resistance.
3. Corrosion resistance, anti-aging, long service life. Carbon fiber rods can resist acid, alkali, salt, some organic solvents and other corrosive erosion, in the field of anti-corrosion can not be compared with other metals. It has good water resistance and aging resistance, so it can be used in corrosive environments, harsh open air and humid environments. The service life of the composite can be up to 15 years or more.
Disadvantages of carbon fiber composites
1. Poor abrasion resistance. After carbon fiber molding, you can directly use ordinary sandpaper to grind down the carbon powder.
2. Higher price. Due to his complex process, limited production, so the price will be more expensive.
3. Brittle and easy to break. This shortcoming makes it very difficult to machine.
With the rapid development of science and technology, high-performance carbon fiber in machinery manufacturing, defense industry, aerospace industry and other fields. The composite material is widely used. It has high specific strength to modulus, strong designability, good fatigue resistance, corrosion resistance and ease of large areas of the overall molding and other significant characteristics. It has better performance than traditional steel, aluminum alloy and other structural materials.
