The UD (unidirectional) and 3K (3,000 fiber bundles) of carbon fiber cloth mainly lie in structure and application. The fibers of UD cloth are all arranged in one direction, providing extremely high strength and rigidity and suitable for applications requiring one-way load-bearing. 3K fabric is made of fiber bundles interwoven into a more flexible fabric, which is suitable for multi-directional load-bearing and is easy to shape and process.
There are several major differences in performance between carbon fiber cloth UD (unidirectional) and 3K (3,000 fiber bundles):
1. Strength and rigidity:
o UD cloth: It has very high tensile strength and rigidity in the fiber direction and is suitable for bearing loads in one direction.
o 3K cloth: Although the strength is not as good as UD cloth in one direction, it provides good strength in all directions and is suitable for multi-directional loads.
2. Weight:
o UD cloth is generally lighter than 3K cloth due to its efficient use of materials.
3. Flexibility:
o UD cloth: relatively inflexible, suitable for structural parts or areas requiring high strength.
o 3K cloth: Due to its fabric structure, it is more flexible, easy to shape, and suitable for complex curved surfaces and structures.
4. Processability:
o UD cloth: requires precise cutting and laying, suitable for high-precision structural parts.
o 3K cloth: easier to lay and process, suitable for large-area composite material molding.
5. Cost:
o Due to different production processes and materials, the cost of UD cloth may be relatively high.
