Carbon Fiber application and cutting-edge technology supplier
1.Application of carbon fiber in thermoplastic modified engineering materials
2.Application of carbon fiber in epoxy thermoplastic prepreg
3.Application of carbon fiber in carbon fasteners
C/C fastener is a commonly used fastener with the following characteristics and advantages: 1, high strength: C/C fasteners are made of carbon fiber reinforced materials, with very high strength and stiffness, can withstand a large load. 2, lightweight: compared with traditional metal fasteners, C/C fasteners have lower density, so light weight, suitable for occasions with high weight requirements. 3, corrosion resistance: C/C fasteners have good corrosion resistance and are not eroded by common chemical substances, and are suitable for use under various environmental conditions. 4, high temperature resistance: C/C fasteners can maintain stable performance in high temperature environment, without thermal expansion or loosening problems. 5, high precision: The manufacturing process of C/C fasteners is high precision, which can provide high connection accuracy and ensure the accuracy of assembly. 6, fire resistance: C/C fasteners have high fire performance, not easy to burn, can provide additional safety protection in emergency situations such as fire. 7, insulation: C/C fasteners are a non-metallic material, with good insulation properties, can be used for occasions that require electrical insulation. In general, C/C fasteners have the advantages of high strength, lightweight, corrosion resistance, high temperature resistance, high precision, fire protection, insulation, etc., and are suitable for fastening needs in various industrial fields and special environments.
4.Application of sizing agent and oil agent in carbon fiber
Sizing agent is the most important component of carbon fiber, and its main function is to protect the carbon fiber, reduce the hairiness and breakage of the carbon fiber in the subsequent deep processing process, as well as the surface active functional groups of the fiber after surface treatment. The effect of sizing agents on the surface of carbon fibers is mainly manifested in the following aspects: firstly, similar to adhesives, improving the fiber's bundling function, improving its processing performance, and facilitating subsequent processing; The second is similar to coupling agents, which improve the chemical bonding between carbon fibers and resin interfaces and improve interface performance; Thirdly, it is similar to a wetting agent to improve its surface wetting performance, shorten resin impregnation time, and improve product production quality; The fourth is similar to lubricants, which protect the surface of carbon fibers, reduce friction during subsequent processing of carbon fibers, and minimize the damage they suffer; Finally, the slurry film has a certain reinforcing effect on carbon fibers, and the sizing process can to some extent compensate for fiber defects.
Oil agent is the most important auxiliary agent for producing high-performance PAN based precursor. Compared to general textile finishing agents, PAN based precursor specific oil agent not only has properties such as bundling, anti-static, friction resistance, and lubrication, but also has special properties such as high temperature resistance, anti melting, and anti adhesion. Research data shows that an excellent oil additive can contribute up to 10% to 30% of the tensile strength of carbon fibers. Oils can generally be divided into high silicon, low silicon, and silicone free oils, which are selected according to the different needs of customers.
