Product Description

Carbon Fiber Plants

Fortune Cat^® Carbon Fiber Production Base specializes in the research and development, as well as production, of PAN-based carbon fiber precursor, carbon fiber filaments, carbon fiber composite materials, and carbon fiber products. Fortune Cat^® can provide customers with integrated full industry chain services, including carbon fiber precursor, carbon fiber filaments, carbon fiber fabrics, liquid resins, adhesives, carbon fiber prepreg, carbon fiber composite components, and aviation composite structural components. The production capacity can reach 40000 tons of carbon fiber precursor and 20000 tons of large tow carbon fiber per year. By testing, the 48K carbon fiber produced by the Fortune Cat^® carbon fiber production base has a tensile strength of 4000Mpa, a tensile modulus of 240Gpa, and an interlayer shear strength of 60Mpa.

PAN based carbon fibers can be divided into small and large fiber tows according to fiber tow size. Fiber tows below 24k refer to small tow carbon fiber, which consist of 1000-24000 individual fibers; And the specification of large tow carbon fiber is ≥ 48k, which means that the number of single fibers in the bundle exceeds 48000. In addition to distinguishing between simple tow specifications, there are significant differences in mechanical properties and application fields between small and large tow carbon fibers.

Small tow carbon fiber has excellent mechanical properties, with a tensile strength of 3.5-7.0 GPa and a tensile modulus of 230-650 GPa. It is mainly used in aerospace, defense and military industries, as well as high-end sports and leisure products, and is therefore also known as aerospace grade carbon fiber. Aerospace grade small fiber tows have extremely strict requirements for reliability, processability, stability, and so on.

Large tow carbon fibers have a tensile strength of 3.5-5.0 GPa and a tensile modulus of 230-290 GPa, and are generally used in fields such as textiles, medicine and health, electromechanical, civil engineering, transportation, and energy, hence they are also known as industrial grade carbon fibers. The technical barriers for large tow carbon fiber are quite high. As an industrial grade carbon fiber, its core driving force lies in low cost, so enterprises must effectively control production costs. The rapidly growing global wind power industry has brought business opportunities for the development of Fortune Cat^®‘s large tow carbon fiber.

In the subsequent application process of large tow carbon fiber, due to the large size and easy aggregation of fiber bundles, the yarn spreading effect is not good, which leads to poor resin infiltration into the fibers and is prone to defects such as pores. In addition, during the process of developing large tow carbon fibers, there may be disordered and broken yarns, resulting in significant dispersion of mechanical properties, further increasing the difficulty of applying large tow carbon fibers.

In the medical field, carbon materials have advantages such as good biocompatibility, low irritation to living tissues, non-toxic, non-carcinogenic, low specific gravity, and similar elastic modulus to human bone, making them a potential fourth generation implant material.

In the field of transportation, the application of large tow carbon fiber is mainly in civil aircraft, automobiles, fast trains, and other transportation vehicles. For example, it can be used to manufacture carbon/carbon composite brake systems and automotive transmission shafts, which can significantly reduce the weight of automobiles, thereby reducing energy consumption and improving automotive control systems, which is beneficial for environmental protection and has become the preferred choice for automotive lightweighting.

Carbon fiber has broad application prospects in the energy field. At present, in the field of energy, carbon fiber reinforced composite materials mainly solve two problems. Firstly, improving energy utilization efficiency. For example, carbon fiber used in automotive components can reduce vehicle weight and improve fuel utilization efficiency; The second is to provide clean energy, such as carbon fiber wind turbine blades and carbon fiber wind turbine propellers applied in the wind power field.

In the field of sports and leisure, large tow carbon fiber products mainly include fishing rods, golf clubs, snowboards, badminton rackets, etc.

In terms of infrastructure, large tow carbon fibers can be used to enhance cement. Carbon fiber reinforced cement composite materials have high strength and stiffness, and can be applied in bridges, buildings, and other fields to further increase the service life of buildings.

In the industrial field, carbon fiber can be applied in industries such as papermaking, metallurgy, chemical, textile, and medical machinery. Various components that require working in environments such as high strength, high stiffness, light weight, high temperature resistance, and corrosion resistance, such as various shafts, containers, pipelines, and platforms, can be manufactured using carbon fiber.

Fortune Cat^®’s products mainly include carbon fiber basic materials, high-strength carbon fibers, carbon fiber fabrics, high-performance material fabrics, warp knitted reinforced fabrics, multi axial warp knitted composite materials, advanced carbon fiber composite materials for rail transit, multiple models of high-speed trains, carbon fiber composite material components for maglev trains and aerospace, high-performance prepregs, carbon fiber composite material products, etc. Fortune Cat^®’s carbon fiber product is widely used in aerospace, weapons and equipment, wind turbine blades, photovoltaic thermal fields, high-pressure hydrogen storage, sports and leisure, building reinforcement and other fields.

Carbon Fiber Tow Prepreg

Fortune Cat^® can produce Carbon Fiber Tow Prepreg.

Item Name: Fortune Cat^® Carbon Fiber Tow Prepreg.

Brand: Fortune Cat^®

Fortune Cat^® Carbon Fiber Tow Prepreg is made by pre-impregnating carbon fiber tow. The special formula of epoxy resin allows the material to be stored for a long time at room temperature. The tow is pre-unfolded to a specified width and can be immediately put into use when needed.

Characteristics of Fortune Cat^® Carbon Fiber Tow Prepreg:

1.High precision-The high-precision uniform positioning of pre-impregnated tow improves the freedom of composite material design and manufacturing accuracy.

2.Cost reduction-Eliminating the process of tow infiltration brings faster winding speed, reduces costs, and increases production. No resin loss, reducing operating costs.

3.efficient-Cleaner operation without the need to clean and collect resin residues from all over, making the entire production process smoother and more efficient.

4.cut down the investment-Eliminated resin infiltration tanks, resin mixing mixers, resin replenishment machines, and other facilities for the factory, reducing corresponding equipment and labor costs.

5.High quality-The simplified operation process also reduces the risk of errors and brings higher and more stable product quality.

6.Convenient storage-It can be stably stored at room temperature (20 ° C) for 2 months, and stored in a cold storage (-18 ° C) for more than 6 months. Simplified logistics and operational costs.

Reference curing procedure:

Raise the temperature from room temperature to around 75 ℃ at a rate of 2 ℃ per minute, then raise it to 125 ℃ at a rate of 2 ℃ per minute, and keep it warm for about 2 hours. Cool to around 60 ℃ at a rate of less than 3 ℃ per minute, then remove from the oven and demold.

All the above parameters are general reference data, and actual usage may vary depending on product thickness, mold condition, or other factors. During the winding process, the workpiece can also be directly heated to increase the fluidity of the resin, thereby reducing the insulation time in the curing process. The curing program can also be adjusted in various ways to change resin flowability or product surface quality.
