Who are the three giants of domestic carbon fiber wheel sets?

[IsabelaRose]

Domestic carbon fiber wheel sets are dominated by three major manufacturers: Hengshen, Guangwei, and AVIC Composite. Below is an introduction to carbon fiber: 1. Overview: Carbon fiber (CF or graphite fiber) is a fiber with a diameter of approximately 5-10 micrometers, primarily composed of carbon atoms. 2. Characteristics: Carbon fiber boasts several key features, including high stiffness, high tensile strength, low weight, high chemical resistance, high-temperature tolerance, and low thermal expansion. However, compared to similar fibers such as glass fiber or plastic fiber, they are relatively expensive. 3. Applications: Carbon fiber is extensively used in aerospace, civil engineering, military, motorsports, and other competitive sports.
