A-19 carbon fiber jacquard woven fabric prepreg

Carbon fiber jacquard woven fabric prepreg: a new choice for composite material decoration that integrates aesthetics and performance

Carbon fiber jacquard woven fabric prepreg is becoming an innovative solution in fields such as sports equipment, automotive decoration, and outdoor leisure that require high material "appearance" and performance. This product is made of 1K, 3K, 6K, 12K and other types of carbon fibers as raw materials. Through precision jacquard weaving technology, various patterns such as football pattern, diamond pattern (airplane pattern), and three-dimensional grid pattern are created, perfectly integrating the high-strength characteristics of carbon fiber fabric prepreg with the decorative value of carbon fiber jacquard fabric. Not only does it retain the lightweight and high rigidity advantages of carbon fiber, but it also endows products with high-end visual texture through unique patterns, filling the market gap of traditional carbon fiber prepreg with "monotonous appearance and weak decorative value", and providing "reliable performance and outstanding appearance" material support for products in various fields.

Core advantages: triple value of jacquard aesthetics, stable performance, and multi scene adaptation

1. Jacquard weaving technology, creating diversified high-end pattern texture

The core highlight of carbon fiber jacquard woven fabric prepreg lies in the differentiated process of "jacquard weaving", which is different from the single plain and diagonal structure of ordinary carbon fiber woven fabric. Through computer programming to control the number of weaving needles and routing methods, 1K, 3K, 6K, and 12K carbon fibers are interlaced to form complex and regular patterns during the weaving process, achieving a deep integration of "functional carbon fibers and decorative patterns". At present, the product has achieved standardized production of three mainstream patterns, each with distinct styles and suitable for aesthetic needs in different fields:

• Football pattern: Based on the classic hexagonal grid on the surface of a football, the pattern is symmetrical and full of sportiness. The football pattern made of 1K and 3K carbon fiber is delicate and exquisite, suitable for high-end sports equipment (such as tennis racket frames and snowboard panels), and can transmit sports vitality through the pattern; The football patterns made of 6K and 12K carbon fibers are more rugged and three-dimensional, and can be used for car interior decoration panels, outdoor leisure tables and chairs, enhancing the visual impact of the products.
• Diamond pattern (airplane pattern): arranged in a diamond pattern resembling an airplane porthole, it combines a sense of technology and luxury. The diamond pattern made of 3K carbon fiber is clear and suitable for car center console decorative strips and high-end luggage casings, enhancing the product's high-end attributes; The diamond pattern made of 12K carbon fiber has a stronger three-dimensional effect and can be used for outdoor leisure pavilion brackets and large sports stadium decoration components. It presents a glossy effect of alternating light and dark under light, with rich visual layers.
• Stereoscopic grid pattern: A grid pattern with concave and convex texture is created by changing the density of carbon wire. The three-dimensional grid pattern made of 1K and 3K carbon wire is delicate and smooth, suitable for precision sports equipment (such as golf club grip decoration layer, fishing rod surface), improving grip comfort and visual precision; The three-dimensional grid pattern made of 6K and 12K carbon fibers has a more pronounced concave convex feeling, which can be used for car door decoration and outdoor camping equipment shells. It can enhance anti slip performance and weaken scratches during use through texture, keeping the appearance clean.

The weaving accuracy error of all patterns is controlled within ± 0.1mm to ensure the consistency of the patterns in each batch of products, avoid problems such as "pattern misalignment and deformation", and ensure the uniformity of the decorative effect of the products.

2. Multi specification carbon fiber coverage, balancing aesthetic and performance requirements

The product is built around the "carbon fiber model (K number)" to create a rich specification system. The thickness and strength differences of carbon fibers with different K numbers can match the dual requirements of different fields for product appearance delicacy and structural performance:

• 1K and 3K fine specification carbon wire: The main focus is on "exquisite aesthetics+lightweight". The diameter of 1K carbon wire is only about 7 μ m, and the jacquard fabric texture made is the most delicate, suitable for scenes with extremely high requirements for exquisite appearance, such as high-end watch case decoration layers and precision sports equipment accessories. While ensuring the decorative effect, it can minimize the weight of the product; 3K carbon fiber has a higher cost performance ratio, with a balance between fine texture and strength. It is suitable for small-sized decorative parts in car interiors (such as steering wheel trims and dashboard frames) and outdoor leisure products (such as camping water cup shells), balancing aesthetics and daily strength.
• 6K and 12K coarse specification carbon fiber: Focusing on "three-dimensional aesthetics+high rigidity", the jacquard fabric pattern made of 6K carbon fiber has a stronger three-dimensional sense and excellent impact resistance, suitable for automotive exterior decoration parts (such as body side skirt decorative strips, tail wing surfaces), outdoor leisure table and chair frames, and can maintain pattern integrity and structural stability in complex use environments; 12K carbon fiber has the highest strength and produces jacquard fabric with outstanding rigidity, which can be used for large outdoor leisure facilities (such as sunshade brackets and bicycle frame decorative layers). When subjected to outdoor wind and rain loads, it not only maintains a beautiful appearance but also ensures structural safety.

Ensure that carbon fibers are evenly distributed in the prepreg to avoid pattern deformation or performance degradation caused by local carbon fiber sparsity, while ensuring sufficient infiltration of resin and carbon fibers to enhance the environmental stability of the product.

3. Balancing performance and decoration, suitable for complex usage scenarios

Carbon fiber jacquard woven fabric prepreg, in addition to its aesthetic advantages, does not sacrifice the core properties of carbon fiber. By optimizing the prepreg process (using a modified epoxy resin system), the product has both excellent mechanical properties and environmental adaptability:

• Stable mechanical properties: After testing, the composite material made of 3K football pattern jacquard prepreg has a tensile strength of over 1800MPa at 0 ° and a bending strength of over 1500MPa, far exceeding ordinary decorative materials such as plastics and metal alloys. It is suitable for components that require both decoration and load-bearing, such as car steering wheel frames (which enhance visual texture through diamond patterns and ensure grip safety through carbon fiber strength) and sports equipment grips (which enhance slip resistance through three-dimensional grid patterns and reduce fatigue through carbon fiber lightweighting).
• Environmental resistance and durability: The resin system adds UV resistant and aging resistant components. In outdoor exposure and humid environments, the color retention rate of the pattern reaches over 90%, without fading or cracking. The service life can reach more than 8 years, which is 50% longer than ordinary decorative woven materials. For example, when used for outdoor leisure tables and chairs, it can resist rainwater erosion and ultraviolet radiation, and maintain clear patterns and a brand new appearance even after long-term use; When used for automotive exterior decoration, it can withstand high and low temperature cycles (-40 ℃~80 ℃), avoiding wrinkles and peeling of patterns due to temperature changes.
• Easy processing and adaptability: The product is compatible with mainstream processes such as hot press molding, compression molding, and vacuum bag molding. Whether it is flat decorative panels (such as car center console panels) or complex curved parts (such as sports equipment curved handles), they can tightly fit the mold. After molding, the pattern integrity retention rate is over 98%, and the original pattern texture can be presented without additional polishing or spraying, greatly reducing the cost of subsequent decoration processes.

4. Differentiated design, building market competition barriers

• Differentiation in craftsmanship and patterns: The independently developed "multi K carbon fiber mixed weaving jacquard technology" can achieve staggered weaving of different K carbon fibers on the same fabric (such as 1K and 3K mixed weaving to form gradient patterns), with pattern uniqueness far exceeding that of ordinary jacquard fabric, and the repeatability controlled below 70%; At the same time, exclusive patterns can be developed according to customer needs (such as brand logo customization patterns, industry characteristic patterns), such as customizing football patterns with brand logos for high-end sports brands, and diamond patterns that match the style of car models for automobile manufacturers, to enhance the brand recognition and exclusivity of products.
• Differentiation in the combination of function and aesthetics: Based on the jacquard craftsmanship, special functions can be added to the product, such as adding antibacterial ingredients for outdoor leisure products (such as camping tableware storage boxes), adding flame-retardant ingredients for car interior decoration, achieving a dual value-added of "decoration+function", which is different from ordinary jacquard prepreg that only focuses on appearance.
• Cost and service differentiation: Through large-scale jacquard weaving machine production and resin formula optimization, while ensuring the refinement of patterns, the cost of 1K and 3K conventional pattern products is controlled below the industry average by 12%, providing customers with a "high cost-effectiveness+high aesthetic value" choice; At the same time, we provide a full process service of "pattern design sample production batch production" to assist customers in quickly implementing product solutions and shortening the research and development cycle.
