As we all know, in the aerospace field, the requirements for materials and technical levels are relatively strict. Which plastics will be used in cutting-edge technology? The following we will have a look at it. 

PA

Modified nylon is an important material basis for the development of aerospace technology. The birth of a new generation of aerospace products is often based on the successful development of a large number of advanced new materials, and can also drive the rapid start and application of many new material projects.

Modified nylon material is an important supporting material for our country's aerospace industry, mainly including rubber, engineering plastics, adhesives and sealants.

Modified nylon, as the earliest thermoplastic material applied in the aerospace field, has now become an indispensable part of aerospace materials.

PEEK

PEEK is used in the aerospace field to replace aluminum, titanium and other metal materials to manufacture aircraft interior and exterior parts.

PEEK has a low density and good processing performance, and can be directly processed into parts that require precision. PEEK's good hydrolysis resistance and corrosion resistance make it used to make aircraft exterior parts. PEEK has excellent flame retardancy and is often used for internal parts of aircraft.

Specific application components of PEEK in aircraft:

1. Engine

PEEK is used in most engine applications because its properties are high-temperature resistance and frictional interaction when it touch with lubricating materials. The PEEK material can be used for a long time at a temperature of 260 degrees and can withstand the local overheating of the engine.

2. Aircraft exterior parts

The wear resistance of jet aircraft exterior parts depends on the impact of raindrops or microscopic substances on the surface of the material. Tests show that PEEK has good rain erosion resistance.

3. Aircraft interior parts

PEEK's outstanding flame retardant properties, mechanical properties, creep resistance and fatigue resistance are fully demonstrated by the requirements of air transportation applications. It is easier to process than ordinary structural materials and is suitable for manufacturing transformer casings, battery racks, and fuel pipe brackets.

4. Engine fairing

Such large parts are usually made of low-density metal, which has been replaced by PEEK. The current Boeing 757-200 family of aircraft uses PEEK fairings with an exemplary service record, suggesting that it may be used on other similar high-performance components.

PI

PI occupies an extremely important position in heat-resistant engineering plastics. PI has excellent radiation resistance and corona resistance is better than other engineering plastics. At the same time, PI is resistant to high temperature and low temperature, high tensile strength, and wear resistance.PI can be used in the aerospace field, such as aircraft engine parts, aircraft internal structural parts, etc.
