How to choose between 3K carbon fiber sheets and 12K carbon fiber sheets?

3K carbon fiber sheets are the most common type of carbon fiber products. They present a classic carbon fiber appearance and are lightweight, strong, and easy to manufacture. The elongation at break and ultimate strength of 3K carbon fiber sheets are higher than those of 6K, 9K, or 12K options. 3K carbon fiber sheets are typically used in aerospace, industrial applications, sports, and recreational goods.

12K carbon fiber sheets are easier to manufacture and require less work compared to 3K carbon fiber sheets. Products made from 12K appear larger and sturdier; generally, the larger the weave, the stiffer it is, but it also tends to be heavier.

12K is not suitable for producing certain bicycle components; instead, it is used in industrial robots and scientific equipment.

The carbon fiber sheets produced by Xinhong Industrial Co., Ltd. utilize a hot-pressing molding process, ensuring high product quality with no white spots, bubbles, or uneven patterns. We offer bulk supply and customized processing services. Below are the performance characteristics of 3K/12K carbon fiber products:

Performance: High hardness, high-temperature resistance, strong impact resistance, corrosion resistance against acids, bases, salts, and atmospheric conditions. No creep, low density, small coefficient of linear expansion, smooth appearance, and free from defects like bubbles.

Process: Made from imported epoxy resin-preimpregnated multi-layer carbon fiber fabric, laminated at high temperatures.

Material Options: Available in 3K and 12K carbon fiber with options for plain weave, twill weave, glossy, and matte finishes.

Applications: Industrial components, medical CT bed plates, X-ray grid filters, industrial robot parts, and other sports goods.
