Yancheng Xiangsheng Carbon Fiber Technology Co., LTD. Chopped carbon fiber: Micro reinforcing unit for high-performance materials!

Chopped carbon fiber, as an important reinforcing material for engineering, plays a key role in the field of modern composite materials. This carbon fiber material, which has undergone precise cutting treatment, retains the inherent high strength and high modulus characteristics of carbon fiber. At the same time, due to its discrete form, it has better dispersibility and processing adaptability, providing an effective solution for improving the performance of various composite materials.

In terms of physical form, chopped carbon fibers usually present as short fibers of uniform length, with a length range mostly between 0.1 and 10 millimeters and a diameter maintained at 5 to 10 micrometers. This specific geometric form enables it to form a three-dimensional network structure in composite materials, effectively transmitting and dispersing stress. Compared with traditional continuous carbon fibers, short-cut carbon fibers are easier to mix with resin matrices and are suitable for various molding processes such as injection molding and compression molding, greatly expanding the processing possibilities of carbon fiber composites.

In terms of production technology, the preparation process of chopped carbon fiber emphasizes precise control. After surface treatment, the raw silk is cut to a fixed length using a dedicated cutting device. During this process, the tool parameters and tension system must be strictly controlled to ensure a smooth cut and consistent length. The subsequent grading and screening process further ensures the uniformity of fiber length and avoids agglomeration. Some high-end products will also undergo special surface modification treatments to enhance the interfacial bonding strength with different base materials.

In terms of performance characteristics, Chopped carbon fiber inherits the core advantages of carbon fiber materials. Its tensile strength can reach 3000-5000MPa, the elastic modulus is within the range of 200-400GPa, while maintaining a relatively low density of 1.7-1.9g/cm³. These features make it an ideal choice for lightweight design. In addition, chopped carbon fibers also have excellent electrical and thermal conductivity, corrosion resistance and dimensional stability, endowing composite materials with multi-functional properties.

In terms of application fields, chopped carbon fiber has been widely used in multiple industrial sectors. In automotive manufacturing, it is used to produce lightweight structural components; In the field of electronics and electrical appliances, it is used to manufacture electromagnetic shielding materials; In terms of sports equipment, it is used to enhance the mechanical properties of the products. By being used in combination with other reinforcing materials, a synergistic improvement in performance can also be achieved.

At present, the technology of chopped carbon fiber is still in the process of continuous innovation and development. New surface treatment technologies are constantly emerging, effectively improving the interface performance between fibers and the matrix. The length grading technology is becoming increasingly precise, meeting the demands of different application scenarios. Recycling and reuse technologies have gradually matured, enhancing the sustainability of materials. These technological advancements are driving short-cut carbon fibers towards higher performance and wider applications, injecting new vitality into the composite materials industry.
