Basic knowledge of carbon fiber cloth

With the rapid development of modern technologies such as aerospace, missiles, atomic energy, automobile industry, and construction engineering, it is difficult for existing steel and alloy materials to meet the requirements. However, due to the high elastic modulus and high With the advantages of strength, carbon fiber and its composite materials have played a very wide role in various fields of social construction and development.

What is carbon fiber cloth

Carbon fiber cloth is also called carbon fiber cloth, carbon fiber cloth, carbon fiber woven cloth, carbon fiber prepreg cloth, carbon fiber reinforced cloth, carbon cloth, carbon fiber fabric, carbon fiber tape, carbon fiber sheet (prepreg cloth), etc. Carbon fiber cloth is a unidirectional carbon fiber reinforced product. It is usually woven with 12K carbon fiber filaments. The common thicknesses are 0.111mm (200g) and 0.167mm (300g), and the widths are 100mm, 150mm, 200mm, 300mm, 500mm and others. Special width required for engineering.

Due to the advantages of high strength, high durability, low density, thin thickness, wide applicability, and convenient construction, carbon fiber cloth is widely used in various structural types and structural shapes such as buildings, bridges, and tunnels. And the structural reinforcement of the joints, the principle is to use high-performance carbon fiber cloth with resin-impregnated glue to bond the surface of the concrete component, and use the good tensile strength of the carbon fiber material to achieve the purpose of enhancing the bearing capacity and strength of the component. In recent years, with the continuous development of the fiber cloth industry, more and more industries have also applied carbon fiber cloth, such as aerospace, sports equipment, industrial manufacturing and fire fighting and other fields.

2. Classification of carbon fiber cloth

Carbon fiber cloth has different types according to its carbon fiber precursors, specifications, carbonization and weaving methods:

1. Classified by carbon fiber precursor

It can be divided into PAN-based carbon fiber cloth (more than 90% of the market is this type of carbon fiber cloth), viscose-based carbon fiber cloth and pitch-based carbon fiber cloth.

2. According to carbon fiber specifications

It can be divided into 1K carbon fiber cloth, 3K carbon fiber cloth, 6K carbon fiber cloth, 12K carbon fiber cloth, 24K and above large tow carbon fiber cloth.

3. According to carbon fiber carbonization

It can be divided into graphitized carbon fiber cloth (can withstand high temperature of 2000-3000 degrees), carbon fiber cloth (can withstand high temperature of about 1000 degrees), pre-oxidized carbon fiber cloth (can withstand high temperature of 200-300 degrees).

4. According to the weaving method

It can be divided into woven carbon fiber cloth (mainly: plain cloth, twill cloth, satin cloth, unidirectional cloth, etc.), knitted carbon fiber cloth (mainly: warp-knitted cloth, weft-knitted cloth, circular machine cloth (casing), horizontal machine cloth (rib cloth), etc.), woven carbon fiber cloth (mainly: casing, packing, braided belt, two-dimensional cloth, three-dimensional cloth, three-dimensional woven cloth, etc.), carbon fiber prepreg cloth (mainly: dry prepreg cloth, wet-laid prepreg, unidirectional prepreg, prepreg tape, non-supporting cloth, with supporting cloth, etc.), carbon fiber non-woven fabrics (non-woven fabrics, namely carbon fiber felt, carbon felt, including chopped strand mat, continuous felt, surface felt, needle felt, stitched felt, etc.).
