The aircraft industries and unimaginably large aircraft parts manufacturing and assembling units mostly make use of some typical plastic goods. This is because plastics and some polymers are comparatively light in weight and thus they make the whole body of the aircrafts and flights lighter since the use of any other heavier components may alter the complexities in aerodynamics. Since the year 1970, the use of such kind of plastics has quadrupled. Almost all interior and some of the exterior parts of a modern day aircraft are made with the help of these plastic materials. Some of the specialist military aircrafts and jet fighters use even lighter plastics which may extend flight range which further helps the jet or the aircrafts evade radar detection which is a very vital aspect in surgical missions as far as an air force is concerned.
Advantages of Aeroplastics
Apart from weight oriented advantages, the use of these kind of plastics also has several other merits which are as follows.
Cost efficient fabrication:
Fabricating the material components of an aircraft is a tedious process that requires tiring processes and greater cost. But the use of aero plastics such as poly-ether-ether-ketone (PEEK) may lower the fabrication cost by a great extent and can also make the process a bit simpler when compared to other heavy components.
Corrosion and impact resistance
Since flights and aircrafts, especially the ones used for military purposes often go through weird climatic and environmental changes in addition to accidents that occur due to mist and foggy clouds. Thus to avoid any critical damage and to assure the safety of the passengers and the people in the aircraft, the whole body is designed using metals that are highly corrosion resistance and those metals which offer more flexibility, adjustability and resistance to high degree impacts. These vital properties make aero plastics a very safe and reliable body material of an aircraft.
Transparency, design freedom and nice sealing effect
The aero plastics must also have some minor characteristics such as texture adjustable layer, appropriate physical capacities to allow insertion of windows. The metal must also possess a considerably good sealing property which is an extremely important characteristic to build up an aircraft.
PRIMARILY USED AEROPLASTICS
Some of the most commonly used aero plastics are listed as follows.
- Thermosetting polymide
- Polyamide-imide (PAI)
- Polychlorotrifluoroethylene (PCTFE)
- Stand-off insulators in aircrafts
- Wear pads
- Aircraft tray tables
- Avionic instrument panels
- Other minor interior parts
