At the same time it has high temperature resistance, flame retardant, low density and other characteristics, so PEEK polyether ether ether ketone in the field of aerospace applications have received widespread attention.

PEEK polyether ether ether ketone is a kind of thermoplastic engineering plastics with excellent mechanical properties, high temperature resistance and wear-resistant characteristics, and it is one of the materials that are used more frequently in aerospace and aviation fields. It is mainly used in the field of aerospace and aviation in missile shells, rocket engine shells and other parts.PEEK polyether ether ether ketone has high mechanical strength, good self-lubrication and chemical resistance and other advantages, in the field of aerospace and aviation in a wide range of applications.

1. High temperature resistance

In the field of aerospace, missiles, rockets, etc. need to withstand high-temperature environment, so for the high-temperature performance of the material has high requirements. PEEK polyether ether ether ketone is a kind of excellent mechanical properties, high-temperature characteristics of the engineering plastics, which has good heat resistance and good self-lubrication, can be used for a long time in a high-temperature environment. Therefore, it is widely used in the aerospace field for engine cases, missile cases, aerospace equipment and other parts. For example, in the field of aerospace, the high temperature resistance of missile shells, rocket engine shells and other parts are very important. Missiles and rockets and other equipment, the main operating temperature of 300 ℃ ~ 500 ℃, PEEK polyether ether ketone has a better high temperature resistance characteristics, it can be used for a long time in the environment above 600 ℃.

In addition to high temperature resistance, PEEK polyether ether ketone also has a prominent feature, that is, its dimensional stability is very good. It has good dimensional stability, which allows PEEK Polyetheretherketone to excel in aerospace applications. Its dimensional stability also allows PEEK Polyetheretherketone to maintain high dimensional stability at high speeds.

2. Abrasion resistance

Aerospace components need to withstand a lot of pressure in the actual work, the parts used are mostly high-strength, wear-resistant parts, so it is required to have a high degree of abrasion resistance, PEEK polyether ether ether ketone as a kind of abrasion-resistant materials, can effectively improve the service life of aerospace components. PEEK polyether ether ketone has excellent wear resistance, its wear coefficient reaches 10-7~10-5, which is one of the best wear-resistant materials among metal materials.

In addition, PEEK polyether ether ether ketone has high corrosion resistance, its high temperature resistance to ensure that aerospace parts work at high temperatures will not be damaged, its excellent acid and alkali resistance to ensure that aerospace parts in highly corrosive environment normal work. PEEK polyether ether ether ketone also has self-lubricating, its low coefficient of friction, coefficient of friction is small, can effectively reduce the degree of friction and wear of engine parts.

3. Chemical resistance

PEEK polyether ether ketone has good chemical resistance, can be used in a variety of corrosive environments, such as petroleum, solvents, seawater, acids, alkalis, etc., with good chemical resistance.

4. Fatigue resistance

In the field of aerospace, in order to meet the requirements of practical applications, fatigue-resistant materials need to be used in aerospace components. As aerospace components in the flight process to withstand a complex environment, including air, low temperature, high temperature, radiation, high speed, high altitude, etc.. Therefore, the fatigue resistance of the material requirements are very high, and PEEK polyether ether ketone material has a high fatigue resistance, can be used for a long time in high and low temperature cycles and radiation and other complex environments. Aerospace field for the material requirements are very strict, must meet the actual application requirements, while maintaining excellent performance for a long time, PEEK polyether ether ketone material with good mechanical properties and high temperature characteristics in the field of aerospace has been widely used in the aerospace field, the future will have a broader application prospects in the field of aerospace.

5. High impact strength

PEEK polyether ether ether ketone impact strength is glass fiber reinforced nylon 5 times, more toughness than carbon fiber, so in the aerospace field, PEEK polyether ether ether ketone is a very wide range of engineering plastics.PEEK polyether ether ether ketone impact strength is high, mainly due to its good toughness, in the impact can be absorbed when a lot of energy. Therefore, in the aerospace field, PEEK polyether ether ether ketone has a very high impact strength.

At present, aerospace field in the use of parts and components materials are mainly metal materials. However, with the continuous development of science and technology, the aerospace field needs to use a large number of metal materials to manufacture parts. The higher cost and heavier weight of metal materials, so the aerospace field in the choice of parts materials also gradually began to pay attention to other characteristics of engineering plastics, PEEK polyether ether ether ketone by virtue of its excellent performance, and gradually become the aerospace field indispensable characteristics of one of the engineering plastics.
