A-12 Expanded Carbon Fiber Braided Fabric Prepreg

Expanded carbon fiber woven fabric prepreg: a new choice for composite materials that combines high performance and aesthetic value

In fields such as high-end equipment, consumer electronics, and aerospace that require high material performance and appearance design, expanding carbon fiber woven fabric prepreg is becoming an innovative solution. This product uses widened carbon fiber as the core raw material, forming widened carbon fiber woven fabric through warp and weft weaving, and then producing widened carbon fiber woven fabric prepreg through a professional pre soaking process. The unfolded carbon fiber bundle has excellent straightness, which not only fully releases the tensile resistance of carbon fiber in the fabric, bringing higher mechanical properties, but also endows the prepreg with unique texture aesthetics. The product covers multiple specifications such as 88mm, 1010mm, 1818mm, 2020mm, etc., which not only meets the strength requirements of structural components, but also provides flexible space for product design, filling the market gap of traditional carbon fiber prepreg with "heavy performance, light appearance".

Core Advantage: Triple Breakthrough in Performance, Aesthetics, and Customization

1. Empower the broadening process and maximize the release of carbon fiber mechanical potential

Widening carbon fiber is the core technological highlight of this prepreg. Unlike the traditional process of directly weaving carbon fiber bundles, the product first professionally unfolds the carbon fiber bundles to achieve uniform width and straightness of over 99%. Then, warp and weft weaving is performed to form a widened carbon fiber woven fabric. This process improvement fundamentally solves the problem of performance loss caused by twisting and stacking of carbon fiber bundles in traditional woven fabrics, allowing the tensile resistance of carbon fibers to be fully utilized in the fabric structure.
After testing, the 0 ° tensile strength of the expanded carbon fiber woven fabric prepreg is increased by more than 25% compared to ordinary carbon fiber woven fabric prepreg, and the tensile modulus is increased by 18%. Even in complex stress scenarios, the fluctuation of mechanical properties can be controlled within 5%. Taking the 88mm widened carbon fiber woven fabric prepreg as an example, the components made of it can uniformly transmit stress to each widened carbon fiber bundle when subjected to axial tension, avoiding the risk of fracture caused by local stress concentration; The 2020mm specification, with its wider fiber bundle coverage area, demonstrates more stable bending resistance in large-area structural components such as high-end equipment casings, meeting the structural reliability requirements for long-term use. At the same time, the product density is strictly not less than 5%, ensuring that carbon fibers are evenly distributed in the prepreg and there are no weak performance points with low local fiber content.

2. Multi specification coverage, adapted to the size and performance requirements of different scenarios

The product revolves around the three core parameters of "grid width, thickness, and weight" to create a rich specification system, covering two types of fabric structures: plain weave and twill weave, which can accurately match the usage needs of different fields. The specific parameters are shown in the table below (excerpted core specifications):

Among them, the 1010mm, 1818mm, and 2020mm wide carbon fiber woven fabric prepreg focuses on "lightweight+aesthetics", suitable for consumer electronics and high-end furniture fields that require appearance and texture; The 88mm specification is centered around "high strength+high weight" and is suitable for industrial equipment and aerospace components with strict structural strength requirements. The thickness of different specifications is controlled between 0.08-0.2mm, balancing the lightweight characteristics and structural stability, providing more size options for product design.

3. The texture is beautiful and unique, balancing functionality and visual value

Traditional carbon fiber prepreg often focuses on mechanical properties, and its appearance is mostly a single solid color or simple texture, which is difficult to meet the aesthetic needs of high-end fields. The pre impregnated material of widened carbon fiber woven fabric, with the uniform arrangement of widened carbon fiber bundles and the warp and weft weaving process, forms a unique and regular texture effect - the plain weave structure presents delicate "grid patterns", with clear and symmetrical patterns, visually more exquisite; The diagonal structure presents a smooth "diagonal texture" with a stronger sense of hierarchy, which can be flexibly selected according to the design style of the product.

This aesthetic advantage makes the product highly competitive in consumer electronics (such as high-end laptop cases, smartwatch cases), high-end furniture (such as light luxury style desktops, cabinet panels), luxury accessories (such as high-end luggage frames), and other fields. For example, a notebook case made of pre impregnated 2020mm plain weave widened carbon fiber woven fabric not only reduces weight by 40% compared to a metal case, but also enhances product recognition through a unique grid texture; The 1818mm specification can be used for high-end furniture panels. When paired with a transparent coating, the carbon fiber texture is clearly visible, combining a sense of technology and luxury, breaking the visual limitations of traditional materials.

4. The pre soaking process is mature, ensuring product consistency and process adaptability

The pre impregnation process of widened carbon fiber woven fabric adopts automated precision equipment to uniformly infiltrate modified epoxy resin into the widened carbon fiber woven fabric. The resin content is controlled between 35% -45%, and the impregnation uniformity is above 99.5%, without defects such as bubbles and missing glue. The mature pre soaking process not only ensures the consistency of performance for each batch of products, but also gives the products excellent process adaptability, compatible with mainstream composite material manufacturing processes such as hot press molding, compression molding, and vacuum bag molding.

In the hot press molding process, the resin of the prepreg has good flowability and can fully fill the gaps in the mold. After molding, the surface smoothness of the parts is high and does not require additional polishing; In compression molding, the product has excellent thermal stability, with a curing temperature range of 120-150 ℃ and a curing time that can be controlled within 30-60 minutes, suitable for batch production rhythm. For example, the use of 10 * 10mm widened carbon fiber woven fabric prepreg for molding sports equipment accessories can increase the production efficiency of a single batch by 20% compared to ordinary prepreg, and the product qualification rate remains stable at over 98%, reducing production costs for enterprises.

5. Differentiated design, building market competition barriers

On the one hand, strict adherence to differentiated innovation in widening process, weaving density, and resin formula - for example, the independently developed wire bundle widening technology can achieve wire bundle width error control within ± 0.5mm, far exceeding the industry average of ± 1mm; On the other hand, we provide flexible customized services that can adjust the grid width (such as 12mm, 15mm customized styles), fabric structure (such as satin), and resin type (such as flame-retardant resin, weather resistant resin) according to customer needs, to meet personalized needs in different fields. For example, in response to the demand for interior parts of new energy vehicles, aging resistant 1818mm wide carbon fiber woven fabric prepreg can be customized; In response to the demand for aerospace accessories, high-strength 88mm specifications can be customized to avoid market pressure caused by homogeneous competition.
