Where Can Small Tow Carbon Fibers Be Used?

The raw silk can be divided into small tow and large tow. It is divided according to how many raw silks each bundle of carbon fibers contains. The number of each bundle is 1k~12k, which is called small tow, and the number of each bundle is more than 24k. called a large tow.

In comparison, the price of large tow is cheaper, but in actual use, small tow is still used more. In this article, I will tell you where small tow carbon fibers can be used.

The most common small tow carbon fiber model is 3k, which means that a bundle contains 3000 strands, and other models include 1k, 6k, and 12k. Some people have questioned that the number of precursors of small tow carbon fiber is less than that of large tow, why is the price more expensive? This is because the smaller the tow carbon fiber, the lighter the product, the more valuable it is.

Small tow carbon fibers, often referred to as “tows,” are bundles of individual carbon filaments. These smaller bundles offer unique properties and advantages compared to larger tow sizes. They are commonly used in various applications where their specific characteristics are beneficial. Here are some areas where small tow carbon fibers can be used:

1. Aerospace and Aviation

Small tow carbon fibers find extensive use in the aerospace industry for producing lightweight, high-strength components. They are employed in the fabrication of aircraft and spacecraft structures, including fuselages, wings, tail sections, and interior components. The fine filaments in small tow carbon fibers allow for precise fiber placement and intricate designs, enhancing overall structural integrity.

2. Sporting Goods

Sports equipment manufacturers utilize small tow carbon fibers to create high-performance products. Tennis rackets, golf club shafts, bicycle frames, fishing rods, and archery equipment benefit from the combination of strength, lightweight properties, and customizable stiffness that small tow carbon fibers offer.

3. Automotive Industry

Small tow carbon fibers are increasingly finding applications in the automotive sector, particularly in high-performance vehicles. They are used to manufacture lightweight body panels, interior trims, and chassis components, contributing to improved fuel efficiency and overall vehicle performance.

4. Marine Industry

In the marine industry, small tow carbon fibers are used to produce durable and lightweight boat hulls, masts, and sails. Their resistance to corrosion and high strength-to-weight ratio make them ideal for withstanding the harsh marine environment.

5. Medical Devices

Small tow carbon fibers are used in medical applications such as prosthetics, orthotics, and medical implants. Their biocompatibility, high strength, and lightweight nature make them suitable for creating strong yet comfortable and lightweight medical devices.

6. Industrial Manufacturing

Small tow carbon fibers are employed in industrial applications such as manufacturing machinery, robotics, and automation systems. Their mechanical properties contribute to the production of reliable and precise equipment components.

7. Consumer Goods

Small tow carbon fibers are sometimes used in the production of high-end consumer goods, including luxury items such as watches, jewelry, and high-end accessories. Their unique appearance and high strength can add value and exclusivity to these products.

8. Renewable Energy

In the renewable energy sector, small tow carbon fibers are utilized in wind turbine blades and other components. Their high strength and fatigue resistance make them suitable for withstanding the dynamic loads experienced by wind turbine blades.

9. Electronics and Electronics Enclosures

Small tow carbon fibers are used in the manufacture of electronics enclosures and cases. Their electromagnetic shielding properties and lightweight characteristics are beneficial for protecting sensitive electronic components.

10. Construction and Infrastructure

Small tow carbon fibers can be incorporated into concrete and other construction materials to enhance their strength, durability, and corrosion resistance. This application can lead to longer-lasting and more resilient structures.

The choice of carbon fiber tow size depends on the specific requirements of each application. While small tow carbon fibers offer advantages in terms of precise fiber placement and design flexibility, larger tow sizes might be more suitable for applications where speed of production is a priority.
