The application of short cut carbon fiber in the automotive field has profoundly promoted the upgrading of vehicle performance and material innovation, mainly achieved through the following six technological paths:

1、 Core application scenarios

1). Engineering plastic modification

Short cut carbon fiber, as a reinforcing filler integrated into engineering plastics such as nylon and polypropylene, can improve material rigidity, dimensional stability, and thermal deformation temperature. It is used to manufacture precision components such as throttle bodies and sensor brackets, achieving a balance between lightweight and durability.

2). Brake system innovation

Adding short cut carbon fiber to brake pads, utilizing its high modulus (elastic modulus up to 240GPa) and excellent thermal conductivity, significantly improves braking stability:

Quickly export frictional heat to avoid thermal degradation

Enhance wear resistance and extend component lifespan by over 30%

Reduce high-speed braking noise

2、 Breakthrough in Lightweight Technology

3). Lightweight composite materials

As a reinforcing material for resin based composite materials, short cut carbon fibers can reduce the weight of components by 40-60%

Vehicle body covering: density only 1/4 of steel, strength increased by 3-5 times

Battery enclosure: Enhance heat dissipation efficiency and reduce thermal management energy consumption of new energy vehicles

Chassis structural components: formed through molding process to enhance torsional stiffness

4). NVH performance optimization

The random distribution of short cut fibers in epoxy resin forms a multidimensional damping structure, effectively absorbing broadband vibrations

Reduce interior noise by 15-20dB

Shorten vibration attenuation time by 40%

Improve driving comfort

3、 Extension of cutting-edge technology

5). Electromagnetic compatibility protection

In the high-voltage system of new energy vehicles, composite materials containing 15% short cut carbon fibers can achieve electromagnetic shielding efficiency of over 60dB, ensuring stable operation of the electronic control system. ‌

6). Sustainable Manufacturing Transformation

Compared to traditional metal craftsmanship:

Reduce production energy consumption by 70%

Recyclable resin matrix achieves closed-loop utilization

Corrosion resistance extends the life cycle of components by 2-3 times

With the breakthrough of short cut carbon fiber surface treatment technology (such as sizing agent modification) and 3D printing technology, its penetration rate in the automotive field is rapidly expanding from luxury models to the mainstream market. The latest research shows that for every 10% weight reduction in new energy vehicles, the range can be increased by 6-8%, making short cut carbon fiber one of the key materials to achieve carbon neutrality goals.
