carbon fiber

As a manufacturer of high-performance composite materials, NFD attaches great importance to the research and development and manufacturing of modified composite materials. After continuous innovation and optimization, it can provide customers with effective modification solutions.

Among all NFD composite material modification processes, carbon fiber modification, as an important modification process, has a wide range of research value and application value in achieving high strength, high wear resistance, light weight, and functionalization. The core modification technology is under study.

As a modified additive for thermoplastics, carbon fibers are "flexible outside and inside rigid", lighter in weight than metal aluminum, but stronger than steel. Carbon fibers have high axial strength and modulus, low density, high specific performance, and no creep. Change, non-oxidizing environment, high temperature resistance, good fatigue resistance, specific heat and conductivity between non-metal and metal, small thermal expansion coefficient and anisotropy, good corrosion resistance, good X-ray transmission and Good electrical and thermal conductivity, good electromagnetic shielding, etc., are important materials in the defense and civilian industries, and are a new generation of reinforcing fibers.

High wear-resistant special plastic bearing made of carbon fiber modified material

Using carbon fiber modification technology, NFD can easily realize the "plastic replacement of steel" for thermoplastic materials. By modifying the carbon fiber with different proportions of the base resin, NFD's material engineers can make the original material higher than some metals The multi-characteristics can easily replace some metal market applications, allowing structural components to achieve light weight, high wear resistance, corrosion resistance and other characteristics.

In cooperation with a Chinese company, NFD successfully developed a special plastic bearing for the company with self-lubricating, high wear resistance (abrasion value can reach five times that of metal), high temperature resistance, low noise, long life , The effect is significant.

After specializing in carbon fiber for wear-resistant bearings, NFD's engineers embedded solid grease as tiny particles into a fine mesh structure composed of countless carbon fibers. When the bearing starts to move, these massive tiny solid grease particles are released from these fine grids and quickly fill the entire working surface, thereby improving the comprehensive wear resistance, lubrication performance and bearing service life of the material. When the working area is filled with grease, a layer of self-lubricating isolation film will be formed, and the wear rate of the bearing will be greatly reduced and the noise will be kept low during subsequent use.

At present, this series of bearings have been successfully listed on the market, and have shown more obvious advantages than metal bearings in the tens of millions of motion inspections each year. They have become the target products to replace metal bearings to achieve weight reduction, intelligence, and low cost. The application market is vast.
