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 Mesh Cloth

carbon fiber mesh cloth is a two-way carbon fiber mesh woven with high-strength carbon fiber wire through special processing. It is used together with special polymer mortar for the reinforcement of concrete structures or masonry, resulting in shear-resistant interlocking and grip The wrapping effect provides reliable reinforcement solutions for different structural forms.

Application of Carbon Fiber Mesh Cloth:

■ Bending, shearing and seismic strengthening;

■ Control of cracks in concrete bridge structures;

■ Durable repair and reinforcement of concrete exposed bars or insufficient protective layer

Construction process of Carbon Fiber Mesh Cloth:

1. Prepare wet construction machinery: prepare corresponding mortar spraying equipment according to the actual situation and needs on site.

2. Treatment of the original concrete base: Before spraying the polymer cement mortar, the old concrete surface should be chipped and the surface cleaned up. 1 hour before spraying, water should be sprayed to keep the sprayed surface fully wet.

3. Mixing with jet mortar: The water required for making mortar is 14.3-16.7% of the weight of the mortar, and the mixing time is ≥15 minutes until the mortar is mixed evenly. The mixed mortar should be allowed to stand for 1 minute and re-mixed for 10 seconds before construction. After the construction process begins, do not add additional water.

4. Spray the first layer of mortar on the surface of the structure: spray the first layer of mortar on the rough structure surface. The thickness of the first layer of mortar is 0.5cm. Make sure the smoothness of the mortar after application.

5. Carbon fiber grid cutting: cut the carbon fiber grid according to the actual needs of the project.

6. Lay the carbon fiber grid on the mortar: lay the carbon fiber grid on the surface of the first layer of mortar. The carbon fiber wire direction of the carbon fiber grid needs to be arranged according to the design direction, and the overlap width of the carbon fiber grid is 20cm. During paving, the ends need to be temporarily fixed; to ensure the smoothness of the entire surface of the carbon fiber grid after paving is completed. The carbon fiber grid needs to be pressed into the mortar layer with a trowel. It is necessary to ensure that the fibers of the reinforcing material are as tight as possible.

7. Spraying the second layer of mortar: After the carbon fiber grid is paved, the second layer of mortar can be mixed and sprayed. The thickness of the sprayed mortar is 1.0cm to ensure that there is no leakage of grid fibers The flatness of the entire concrete surface. The first layer and the second layer of mortar must be constructed on the same day. If the second layer of mortar fails to be constructed on the same day, the first layer of mortar needs to be roughened with a broom or low-pressure water gun until the aggregate is visible.

8. Surface smoothing: Use a trowel or scraper to smooth the surface mortar. If it is found that the thickness of the mortar does not meet the requirements, local repair is needed.
