What are the specific fiber materials of tires

The fiber materials of tires specifically include the following:

Rayon:

Features: Artificial silk is made from natural plant cellulose and has the characteristics of low thermal shrinkage, low hysteresis, and low creep rate.

Application: Artificial silk has been widely used as the carcass skeleton material for tires, especially among European tire manufacturers. However, its cost is high, strength and fatigue resistance are low, and pollution may occur during the manufacturing process.

Polyamide fiber (Nylon):

Characteristics: Nylon has excellent strength, toughness, and fatigue resistance, good adhesion to rubber, and is relatively inexpensive. After adding anti-aging agents, the heat resistance of nylon is greatly improved.

Application: Nylon is widely used in tires, especially since the second half of 1955 when it gradually replaced the main position of synthetic silk. Currently, engineers from various countries are also developing nylon to improve its performance.

Polyester fiber (PET fiber for short):

Features: Polyester fiber has high modulus and low elongation, with fatigue and impact resistance between synthetic silk and nylon, and its strength does not decrease after water absorption. The tire body made of polyester has stable dimensions, good high-speed performance and wear resistance, and low noise.

Application: Polyester fiber is widely used in radial tires for ordinary cars and light trucks. However, polyester fibers are more difficult to bond with rubber than synthetic silk and nylon, and are prone to aging in rubber.

Glass Fiber:

Features: Glass fiber has high strength, heat resistance, and good dimensional stability.

Application: In the 1960s, glass fiber was used in tires, but later with the development of the synthetic fiber industry and the solution to the bonding problem between steel wire and rubber, glass fiber has gradually been replaced by synthetic fibers and steel wire.

Aromatic polyamide fibers (aramid, Kevlar):

Characteristics: Aromatic polyamide fibers have high thermal stability, do not melt or burn, high modulus, high strength, and also have high strength at high temperatures.

Application: Aromatic polyamide fibers are more commonly used in high-performance tires, aviation tires, etc. It can reduce tire weight, improve cutting resistance, reduce steel wire usage, etc.

Other fiber materials:

It also includes some special purpose fiber materials, such as carbon fiber, which have extremely high strength and lightweight characteristics, but are very expensive and are usually used in high-performance or special purpose tires.
