Core Advantage
Ultimate lightweight, enhancing battery life and maneuverability: With a density of only about 2.0g/cm³, it is 40% to 60% lighter than traditional metal pipes (such as aluminum alloy and stainless steel). Without sacrificing structural strength, it can significantly reduce the overall weight of the terminal product, helping to enhance the endurance of equipment (such as drones and electric vehicles) and mobility (such as sports equipment and robots).
Ultra-high strength and rigidity, excellent load-bearing capacity: Tensile strength can reach over 3500MPa, elastic modulus as high as 230GPa, specific strength and specific modulus far exceed those of metal materials, can maintain structural stability in complex force environments, effectively resist impact, bending and deformation, and extend the service life of products.
High degree of customization, suitable for diverse scenarios: It can be fully customized according to the customer's drawing requirements for cross-sectional shapes (square, rectangular, elliptical, irregular, etc.), size specifications (length, wall thickness, hole diameter, etc.), fiber layering schemes and surface processes, precisely matching the installation and usage requirements of different equipment, and solving the compatibility problems of traditional standard pipes.
Outstanding corrosion resistance and environmental adaptability: It does not rust or corrode, can withstand harsh environments such as acids, alkalis, salt spray, and humidity (such as Marine, outdoor, and chemical Settings), requires no frequent maintenance, and maintains stable performance at extreme temperatures (-50℃ to 150℃), with a wide range of applicable regions and scenarios.
Low thermal conductivity/electromagnetic shielding is optional, expanding application boundaries: Naturally endowed with low thermal conductivity, it can reduce heat conduction. At the same time, electromagnetic shielding function can be achieved through special layup design, making it suitable for scenarios such as precision electronic equipment and aerospace that have requirements for thermal protection or electromagnetic compatibility.
The surface texture is excellent, combining beauty and practicality: Through fine surface treatment, it can present various textures such as matte, glossy, and color spraying, not only enhancing the appearance grade of the product, but also improving the surface wear resistance and scratch resistance, meeting both practical and aesthetic needs.

FAQ
1. When carbon fiber special-shaped tubes are used in conjunction with metal connectors, how can the problem of electrochemical corrosion be avoided?
Carbon fiber is an inert material. When in contact with metals, it does not cause electrochemical corrosion by itself. However, the potential differences among various metals may lead to corrosion of metal connectors. We offer two solutions: One is to install insulating gaskets (materials can be selected from PTFE, nylon, etc.) at the contact surface between the pipe body and the metal connection parts to block the electrochemical circuit; The second is to carry out cathodic protection treatment (such as galvanizing and nickel plating) on metal connectors. At the same time, we will provide detailed assembly guidance at the time of delivery, explicitly prohibiting direct contact between carbon fiber tubes and active metals (such as magnesium alloys) to avoid corrosion risks from the assembly stage.
2. When customizing carbon fiber special-shaped tubes in bulk, is it feasible to adjust the product specifications during the process? How much longer will the production cycle be after the adjustment?
The feasibility of adjusting specifications during mass production needs to be judged based on the production progress: if the mold processing and raw material cutting have not yet started, the specifications can be adjusted for free. If it has entered the mold processing stage, the mold cost that has already been incurred shall be borne. If mass production has already begun, adjusting the specifications will require a re-evaluation of the production plan and additional costs. Regarding the extension of the cycle, both parties can negotiate and determine it based on the product specifications.
3. What customization forms are supported for carbon fiber special-shaped tubes? Can our own drawings or molds be customized?
We support a variety of flexible customization forms and can fully undertake the customization demands provided by customers with drawings or their own molds. Specifically, it includes the following three core forms: The first is "drawing customization". Customers provide 2D engineering drawings (such as CAD format) or 3D models (STEP, IGES, etc.), clearly marked with dimensions, tolerances, material requirements and application scenarios. We will complete mold development, sample making and mass production based on the drawings. This is the most mainstream customization method, suitable for the vast majority of personalized needs. The second is "customer-provided mold customization". If the customer already has a mature mold, they only need to provide the mold compatibility parameters (such as cavity size, mold opening and closing method) and product performance requirements. We can directly match the mold for production, significantly shortening the development cycle, and at the same time provide mold maintenance and optimization suggestions. The third is "joint development and customization". If the customer only has a product concept or a preliminary plan, we can arrange a professional engineer team to connect and assist in completing the entire process of development, including drawing design, structural optimization, and mold scheme planning, ultimately achieving customized production. All customized forms support small-batch trial production and batch mass production to ensure consistency and stability from samples to finished products.
