What’s PC CF20?

The 20% carbon fiber reinforced polycarbonate composite material (PC CF20) is a material composed of polycarbonate as the matrix and 20% carbon fiber as the reinforcement.

It has many excellent properties. In terms of mechanical properties, its tensile and flexural strengths are greatly enhanced, significantly stronger than pure polycarbonate (tensile strength of about 63 MPa, flexural modulus of about 2300 MPa). The notch impact strength first increases and then decreases with the increase of carbon fiber, and there is a carbon fiber content value at which the impact strength reaches the maximum. Compared with glass fiber reinforced polycarbonate under the same conditions, its other properties are better.

This material also increases antistatic properties. When the carbon fiber content is 10%, the surface resistivity can reach 9.0×10 ω/sq, and it can be used as an antistatic material. In addition, the addition of carbon fiber improves the processability of polycarbonate, which can significantly improve its viscosity and fluidity, but as the carbon fiber content increases, the fluidity will gradually decrease.

This composite material is widely used in aerospace and military fields, such as low outgassing components, components resistant to space debris impact, components resistant to space radiation, etc.; it is also used in the manufacture of special parts; it can also be used in products such as tent poles and golf bag poles in the field of sports and leisure.

Its specific properties may vary due to factors such as production processes and other added components. In practical applications, it is necessary to select the appropriate material and ratio according to specific needs and usage environments.

Application of PC CF20 in New Electric Bicycles

In the bustling and noisy urban transportation field, the PC 20%CF carefully developed by Carbon (Xiamen) New Material has been ingeniously applied to the frame manufacturing of new electric bicycles, showing a series of remarkable advantages.

The PC CF20% has extraordinary and excellent strength characteristics. Compared with traditional materials, it can withstand greater impact force and pressure. Even in the complex and changeable driving process, encountering extreme situations such as severe bumps and unexpected collisions, the frame can be tough and hardly deformed or damaged. This undoubtedly builds a solid safety barrier for cyclists. For example, when cyclists rush over raised road bumps at high speed or unfortunately fall accidentally, the frame can still maintain its original complete structure, strongly avoiding various hidden dangers that may endanger the personal safety of cyclists.

The lightweight characteristic of PC 20% CF can be regarded as a dazzling highlight. This feature significantly reduces the weight of the entire electric bicycle, allowing cyclists to experience unprecedented ease and flexibility when manipulating the vehicle. Especially in the urban road environment where traffic is congested and frequent stops and sharp turns are required, its advantages are even more prominent. For example, for female cyclists with relatively weak strength and elderly cyclists with slightly slower reactions, they can also control the vehicle effortlessly and freely shuttle through the streets and alleys.

PC CF20 also has outstanding heat resistance. In the scorching hot summer, even if long-term riding causes the frame temperature to continue to rise, it can still firmly maintain stable mechanical properties and will not show any softening or strength decline. This means that even in long-distance riding in extremely hot weather, the frame can remain highly reliable from beginning to end.

In addition, its good corrosion resistance is even more outstanding. The frame can stubbornly resist the erosion of rainwater, the infiltration of moisture, and the erosion of various chemical substances. Whether riding in the rainy and humid season or in coastal areas with a high salt content, the frame can consistently maintain a good appearance and excellent performance over a long period of time, greatly reducing maintenance costs and maintenance frequency.

To sum up, the ingenious application of PC CF20 in the frame of electric bicycles, with its unparalleled strength, lightweight and convenient lightweight, stable and reliable heat resistance and indestructible corrosion resistance and other advantages, has brought a revolutionary qualitative improvement to the overall performance and reliability of electric bicycles.
