Carbon fiber composite materials, as a representative emerging composite material, have emerged in many fields. Many of their properties are more outstanding than traditional metal materials, and the properties that metals can possess will not fall behind and are even more outstanding. Even properties that metals do not have, they have. This is why it frequently appears in many fields. Let's talk about its outstanding advantages in detail below.


Many manufacturers hope that the products they produce will not feel bulky. The density of carbon fiber composite material is only 1.6 grams per cubic centimeter, which is a very small number. Therefore, products made with it can solve this problem very well. Perhaps some people may worry that such lightweight, support performance, and specific strength will not be too high, and the so-called two cannot be achieved simultaneously. However, carbon fiber composite materials have the highest specific strength among existing structural materials.


The working temperature of carbon fiber composite materials is high, such as aluminum alloy materials, which work at 200-250 degrees. If the temperature continues to rise, its elastic modulus and strength will decrease significantly. The performance of the produced product has significantly decreased. Carbon fiber composite materials can still maintain their physical properties under high temperature conditions.


The performance degradation caused by environmental degradation is inevitable. Under outdoor natural conditions, its anti-aging performance is gradually emerging due to the effects of sunlight, radiation, etc. For some chemical corrosion, ordinary acids, alkalis, and salts have little effect on it and can still maintain good performance.
