Aramid woven fabric is a high-performance textile with a variety of applications as follows:
Protection Field
- Bulletproof Protection: Aramid woven fabric has high strength and good toughness, enabling it to effectively absorb and disperse the impact force of bullets. For example, it is widely used in rescue equipment and bulletproof vests. Its weaving structure allows it to withstand the impact of high-speed bullets and prevent bullets from penetrating, thus protecting vital organs of the human body.
- Anti-stabbing Protection: It can resist the puncture of sharp objects like knives. It is used in the protective clothing of security personnel, anti-stabbing gloves and other equipment, providing reliable anti-stabbing protection for users.
- High-temperature Protection: The aramid material itself has good high-temperature resistance. Aramid woven fabric can protect the human body from flame and heat radiation in high-temperature environments. For instance, in fire-fighting suits, it can help firefighters reduce heat conduction to their bodies when working close to the fire source, improving the safety of firefighters' operations.
Aerospace Field
- Auxiliary Material for Aircraft Structural Components: It is used as decorative materials inside the aircraft and as auxiliary materials for some structural parts that require high strength and flame retardancy. For example, in the manufacture of aircraft seats, aramid woven fabric can provide good strength and flame retardant properties to ensure the safety of passengers.
- Components of Thermal Protection System for Spacecraft: When spacecraft re-enter the Earth's atmosphere, they have to endure high-temperature environments. Aramid woven fabric can serve as part of the thermal protection system, helping to resist the high temperature generated by atmospheric friction and protecting the instruments, equipment and structural integrity inside the spacecraft.
Automotive Industry Field
- Reinforcing Material for Automobile Tires: It is added to the cord fabric of automobile tires to enhance the strength and anti-fatigue performance of tires, enabling tires to withstand greater loads and friction and improving the service life and safety of tires.
- Flame-retardant Material for Automobile Interiors: It is used in parts such as automobile seats and interior panels, which can play a flame-retardant role, reduce the risk of fire in automobiles, and also provide certain abrasion resistance and comfort.
Electronic and Electrical Appliance Field
- Insulating Material for Circuit Boards: As an insulating material for circuit boards, aramid woven fabric can prevent short circuits in circuits. Meanwhile, its mechanical properties can protect circuit boards from being damaged when subjected to external forces, ensuring the stable operation of electronic devices.
- Protective Material for the Housings of Electronic Products: It is used in the housings of some high-end electronic products, which can provide multiple protection functions such as impact resistance, abrasion resistance and flame retardancy, improving the durability of electronic products.
Sports and Leisure Field
- Material for Sports Equipment: It is used to manufacture high-end sports equipment, such as sails of sailboats, surfboards, etc. The high strength and lightweight features of aramid woven fabric can ensure the strength of the equipment while reducing its weight and enhancing the sports experience. It is also applied in the manufacturing of the uppers of sports shoes to enhance the support and abrasion resistance of the uppers.
- Material for Outdoor Clothing: Some outdoor exploration clothing adopts aramid woven fabric because it has multiple properties such as windproof, waterproof, abrasion-resistant and flame-retardant, which can adapt to complex outdoor environments.
Aramid woven fabric has the following advantages and disadvantages:
Advantages
- Excellent mechanical properties
- High strength: Aramid woven fabric has very high strength, and its tensile strength is usually much higher than that of ordinary fiber fabrics. For example, the tensile strength of aramid fiber can reach more than 3000MPa, which enables the fabric made from it to withstand relatively large tensile forces without breaking. In the aerospace field, when used as auxiliary materials for aircraft structural components and components of the thermal protection system of spacecraft, this high strength can effectively resist various stresses during flight.
- Good toughness: It has outstanding toughness and can absorb energy when impacted or stretched without being easily damaged. In the protection field, such as in bulletproof vests and anti-stabbing gloves, this toughness can effectively disperse the impact force of bullets or sharp objects and protect human safety.
- Outstanding thermal stability
- High temperature resistance: Aramid woven fabric can maintain stable performance at relatively high temperatures. Its long-term service temperature can reach above 200 °C, and it can even withstand higher temperatures in a short period of time. In the production of fire-fighting suits, it can effectively block heat transfer when firefighters approach the fire source, reducing heat damage. When spacecraft re-enter the Earth's atmosphere and face the high temperature generated by atmospheric friction, aramid woven fabric can also play its role in high temperature resistance to protect the equipment and structural integrity inside the spacecraft.
- Low thermal shrinkage: In a high-temperature environment, aramid woven fabric has a relatively low thermal shrinkage rate. This means that under high-temperature conditions, it will not undergo severe shrinkage and deformation like some ordinary fabrics, thus ensuring its stability and reliability in use.
- Excellent flame retardant properties
- Self-extinguishing: Aramid woven fabric has good flame retardancy and can extinguish itself once it leaves the fire source. This is because the chemical structure of aramid fiber enables it to form a carbonized layer on the surface during combustion, which prevents the further spread of the flame. In automobile interiors, the casings of electronic appliances and various places where fire prevention is required, this self-extinguishing property can effectively reduce the risk of fire.
- Low smoke and non-toxic: It produces less smoke when burning and does not release a large amount of toxic and harmful gases. This is very beneficial for the escape and rescue work of people in a fire environment and also meets the requirements of environmental protection and safety.
- Good chemical stability
- Resistance to acid and alkali corrosion: Aramid woven fabric has relatively good tolerance to chemical substances such as acids and alkalis. It can maintain stable performance in an acid and alkali solution environment with a certain concentration for a long time, which enables it to resist chemical corrosion and extend its service life in applications in fields such as chemical engineering and electronics.
- Strong resistance to chemical substances: Besides acids and alkalis, it also has good resistance to other chemical substances. For example, in the application of circuit board insulating materials, it can prevent performance degradation caused by contact with chemical substances.
- Other advantages
- Good abrasion resistance: In the sports and leisure field, the good abrasion resistance of aramid woven fabric makes it an ideal material for manufacturing sports equipment and outdoor clothing. For example, in the uppers of sports shoes and outdoor exploration clothing, it can withstand long-term friction without being easily damaged and maintain good appearance and performance.
- Good electrical insulation: It can be used as an insulating material in the field of electronic appliances to effectively prevent short circuits in circuits and ensure the safe operation of electronic devices.
Disadvantages
- Relatively strong hygroscopicity
Aramid woven fabric has a certain degree of hygroscopicity, which may affect some of its properties. For example, in a high-humidity environment, the fabric may absorb more moisture, resulting in a slight decrease in its strength and modulus. In some application scenarios where extremely high material performance requirements are imposed, such as the protection of precision instruments and equipment or in the aerospace field, such performance changes may bring certain risks.
- Relatively high price
The production cost of aramid fiber is relatively high, resulting in a relatively high price for aramid woven fabric. This restricts its large-scale application in some fields that are sensitive to cost. For example, in ordinary civilian clothing or some low-end products, due to price factors, aramid woven fabric is rarely used.
- Difficult processing
- Complex textile process: Aramid fiber has high strength and rigidity, and in the textile process, relatively high requirements are imposed on textile equipment and processes. Special textile machines and techniques are needed to ensure smooth weaving. For example, during the processing and weaving of yarns, problems such as fiber breakage and fluffing are prone to occur, increasing the processing cost and difficulty.
- Poor dyeing performance: It is relatively difficult to dye aramid woven fabric because its fiber has a stable chemical structure and is not easy to combine with dyes. This leads to a relatively limited choice of colors, usually only some basic colors are available, which to some extent restricts its application in the clothing and decoration fields where rich colors are required.
