A-15 metal wire carbon fiber cloth prepreg

Metal wire carbon fiber cloth prepreg: an innovative composite material solution that combines functionality and decoration

In various fields such as wind power generation, sports equipment, automobiles, ships, etc., materials not only need to meet structural performance requirements, but also need to consider appearance and decorative value. The metal wire carbon fiber cloth prepreg is made of "carbon fiber cloth+colored metal wire" as the core substrate, and is formed by weaving multi-color metal wires into the metal wire carbon fiber cloth in the weaving process, and then made through professional prepreg technology. The product covers four major specifications of 1K, 3K, 6K, and 12K, including plain and diagonal fabric structures. The metal wire color can be flexibly selected, retaining the high-strength characteristics of carbon fiber while giving the material a unique metallic luster decorative effect.

Core advantage: Triple value of innovative decoration, stable performance, and multi scenario adaptation

1. Metal wire weaving process to create high aesthetic decorative effects

The core highlight of metal wire carbon fiber cloth prepreg lies in the fusion weaving process of "functional carbon fiber and decorative metal wire". Different from the traditional black appearance of carbon fiber cloth, this product weaves metal wires of different materials such as copper wire, aluminum wire, and stainless steel wire in precise proportions during the weaving process of carbon fiber cloth. The metal wire colors support multi color customization such as gold, silver, antique copper, rose gold, etc., forming an appearance effect that combines technology and luxury.
Products with different specifications and fabric structures have their own emphasis on decorative styles:

• Plain weave structure: 1K and 3K plain weave metal wire carbon fiber cloth prepreg has a delicate and tight texture, and the metal wire is evenly distributed in the carbon fiber grid, presenting a "low-key sparkling silver/sparkling gold" effect, suitable for scenes with high requirements for exquisite appearance, such as high-end sports equipment (golf club shafts, bicycle frames), and car interior decorative panels;
• Diagonal structure: 6K and 12K diagonal metal wire carbon fiber cloth prepreg has a more layered texture, and the metal wire forms smooth "metallic luster lines" along the diagonal direction, with stronger visual impact. It is suitable for large components such as wind turbine blade guide covers and ship interior panels, which can improve product recognition and weaken the monotony of industrial products.

This decorative advantage allows the product to possess both the structural properties of carbon fiber fabric prepreg and the aesthetic value of carbon fiber decorative fabric, without the need for additional spraying or film coating. Once formed, it can present a metallic appearance, significantly reducing the cost of subsequent decorative processes.

2. Collaborative performance improvement, balancing structural strength and environmental stability

The addition of metal wire not only optimizes the appearance, but also enhances the comprehensive performance of the prepreg to a certain extent. On the one hand, metal wires (such as stainless steel wire and copper wire) themselves have certain strength and toughness. When combined with carbon fiber weaving, they can enhance the shear resistance and impact resistance of prepreg. After testing, the shear strength of 3K plain metal wire carbon fiber cloth prepreg is 12% higher than that of ordinary 3K carbon fiber fabric prepreg, and the impact toughness is increased by 8%. It is more durable in impact prone scenarios such as sports equipment and automotive parts; On the other hand, metal wires can enhance the thermal and electrical conductivity of prepreg. Some models (such as prepreg containing copper wires) have a 30% increase in thermal conductivity compared to ordinary carbon fiber prepreg, and can be used for components that require local heat dissipation, such as automotive electronic device casings.

At the same time, the product optimizes the pre impregnation process and uses modified epoxy resin as the bonding system to ensure a tight bond between carbon fiber, metal wire, and resin, without the risk of interface peeling. In the environmental stability test, the product performed excellently: after being placed in high and low temperature cycles of -40 ℃~80 ℃ for 500 times, the mechanical performance retention rate reached over 85%; After soaking in a salt spray environment for 300 hours, the metal wire remains rust free and the appearance does not fade, fully meeting the long-term usage needs of outdoor or high humidity scenarios such as ships and wind power.

3. Strong process adaptability to meet the production needs of multiple fields

Metal wire carbon fiber cloth prepreg is compatible with mainstream composite material manufacturing processes such as hot press can molding, compression molding, vacuum bag molding, etc., without the need for enterprises to adjust existing equipment, adapting to the production rhythm and component form requirements of different fields:

• Compression molding: suitable for standardized and mass-produced components, such as sports equipment (golf clubs, ski bindings), automotive interior parts, with high molding efficiency, single batch production time can be controlled within 30-60 minutes, and can accurately replicate the texture details of metal wires to ensure consistent appearance of each product;
• Hot press molding: Suitable for high-end components that require high precision and performance, such as wind turbine blade guide covers and high-end interior panels for ships. By controlling uniform pressure (0.8~1.5MPa) and temperature (120~150 ℃), the resin is fully immersed in carbon fibers and metal wires, resulting in high surface smoothness and fuller metal luster of the molded components;
• Vacuum bag forming: suitable for large and complex shaped components, such as ship cabin wall panels and large wind power components. Resin exhaust is achieved through vacuum negative pressure to avoid bubbles affecting appearance and performance. The forming cost is reduced by 35% compared to the hot press tank process, balancing economy and product quality.

In addition, the product has excellent storage stability and can be stored for more than 6 months in a low temperature environment of -18 ℃. After being taken out and warmed up for 30 minutes, it can be put into production without worrying about oxidation or separation of metal wires and carbon fibers, ensuring production continuity.

4. Differentiated design, building market competition barriers

On the one hand, differentiated innovation is carried out in the selection of metal wire materials, weaving ratios, and resin formulations - for example, the independently developed "anti-corrosion metal wire treatment process" can extend the anti rust life of metal wires in salt spray environments to more than 5 years, far exceeding the industry's average level of 3 years; On the other hand, we provide flexible customized services that can adjust the color of metal wires according to customer needs (such as customizing special color schemes to match brand VI), weaving density (adjusting the proportion of metal wires to control glossiness), and fiber specifications (such as customizing 8K special specifications) to meet personalized needs in different fields. For example, customizing "brand exclusive color metal wire prepreg" for high-end car brands for interior decoration; Customize "high weather resistant metal wire prepreg" for outdoor blade guide covers for wind power enterprises to avoid homogeneous competition and provide customers with unique product selling points.
