Excellent Electromagnetism Property Round 70MM Carbon Fibre Tube

All carbon fibres we use in carbon fibre tube production are in prepreg form. Prepreg fibres are those that have been pre-impregnated with a resin system. As a matrix, we use epoxy resin with high homogeneous weight. We use different carbon fibre grades for carbon fibre tube production, depending on the desired mechanical properties. We use only high-quality epoxy matrix with a Tg under 100 degrees Celsius and a completely transparent look.

Carbon fiber is made of thin, strong crystalline filaments of carbon that are used to strengthen the material. Carbon fiber can be thinner than a strand of human hair and gets its strength when twisted together like yarn. Then it can be woven together to form cloth and if needed to take a permanent shape, carbon fiber can be laid over a mold and coated in resin or plastic.

On top of being strong, carbon fiber:
● Is high in stiffness
● Is high in tensile strength
● Has a low weight-to-strength ratio
● Is high in chemical resistance
● Is temperature tolerant to excessive heat
● Has low thermal expansion

Because of this, carbon fiber is very popular in many industries such as aerospace, automotive, military, and recreational applications.

With advanced management concept, strong technical strength, and forward-looking thinking, the company has gradually formed a product system with three major plates of pultrusion, hand paste, and carbon fiber, with FRP radome and bus air conditioning shell as the leading products, FRP profiles, carbon fiber profiles and other categories of common development products. The products are widely used in mobile communication, automobile, construction, environmental protection, and rail transit.

Since its establishment, the company has been taking honesty and pragmatism as its purpose, product quality as its life, and customer satisfaction as its pursuit, fully implemented and implemented ISO 9001:2015, established and improved a set of standardized, standardized, and procedural quality management system, products are exported to more than 30 countries, such as Europe and the United States, Southeast Asia, Australia, the Middle East and so on. It is well received by customers.

A Brief History of Carbon Fiber

Carbon fiber dates back to 1879 when Thomas Edison baked cotton threads or bamboo silvers at high temperatures, which carbonized them into an all-carbon fiber filament. By 1958, high-performance carbon fibers were invented just outside of Cleveland, OH. Although they were inefficient, these fibers contained around 20% carbon and had low strength and stiffness properties.

In 1963 a new manufacturing process was developed at a British research center, which is where carbon fiber’s strength potential was realized.

How is Carbon Fiber Made: An Overview of The Carbon Fiber Manufacturing Process

Carbon fiber is made from a process that is part chemical and part mechanical. It starts by drawing long strands of fibers and then heating them to a very high temperature without allowing contact with oxygen to prevent the fibers from burning. This is when carbonization takes place, which is when the atoms inside of the fibers vibrate violently, expelling most of the non-carbon atoms. This leaves a fiber composed of long, tightly interlocked chains of carbon atoms with only a few non-carbon atoms remaining.

Typical sequences used to form carbon fibers from polyacrylonitrile involve spinning, stabilizing, carbonizing, treating the surface, and sizing.
