  plastics property can make its suitable for aviation aerospace application, this is is what 45 year in, plastics parts in aviation aerospace design in use 翻 两番. plastics light 便, corrosion resistant property, heat stabilized property and machine stability property and other features make plastics in aviation field/area application add 广泛, more add heavy plastics development utilizing, aviation plastics 演变证明 plastics development speed.
 
   plastics weight ratio metal light more, this make its combined used for more design and more light 质 飞 machine parts, and can belt/tape large material 节约. in weight strong/high degree ratio upper advantages 意味, need to and other strong/high degree, plastics weight has metal separation 之一, or is aluminum semi. plastics also can is machine poor ring application provide corrosion resistant property, and versus for relatively high heat stabilized property and machine stability property.
 
   and versus ratio, transparent plastics in aviation manufacturing in application has large advantages. transparent plastics parts weight more light, can provide ratio more high resistant impact property, this for machine positive is key/critical safety factors. transparent plastics can through types methods molding, made as formed solid, transparent also complex parts.
 　 in many machine application in, for/regarding bearings and requirements has high surface lubricated property, has 时候因 is its 处 位置而 very difficult lubricated. new lubricated plastics technology in many lower can solution this issues, can achieve long use lifespan 而无需 most low degree 维护.
 
   as is types high electrical insulation 体, plastics is aviation aerospace application selection. many plastics tool has this type of insulation can force, provide a large amount of material selection, has plastics provide is 接近零 electrical rate. in application in, plastics for/regarding 雷达 说 is types has insulation material, use anti by 发现.
 
   in addition, plastics in design in can provide large active property. 如今, engineering has multiple high property can thermoplastic property plastics and composite/compounding material can selection, can very good meet/satisfy application high requirements.
 
   most rear, plastics parts manufacturing 总体 说 comparison 经济, key/critical is from manufacturing methods in 选出适 combined large more project most methods.
 
   aviation plastics parts 演变
 
   from history 看, aviation aerospace industrial and plastics industrial time non 常接近——都 is in world large 战.
 
  战争 出现 accelerated in use machine development. 1940 year, USA 总统罗斯福 increase use machine year production amount, from 10000 increase 至50000以支持战争. meanwhile, key/critical industrial material metal and 橡胶出现 short 缺, fast speed plastics in manufacturing in application, aviation manufacturing.
 

  随 engineering 师发现 new methods utilizing plastics property can, formed 功 连锁 reaction by 引发. in 20世纪60 year and 70 year 代, high property can plastics development new large 门. 今天, aviation plastics parts by 广泛投入FAA批准 parts market, this type of most fast, most tool cost 效益 材 material can aviation manufacturing obtain 需 零部 parts. plastics parts a large amount of in aviation aerospace field/area, from machine 身零部 parts to sleeve/set, bearings, 支架以 and more more.

 　　 aviation application in many plastics parts is machine processing, is molding or pressure. need substitute/replace parts amount has 限时, machine processing is most good selection, this is is can achieve non high property can and degree, and aviation aerospace design non 常紧密 公差.
 
   in addition, machine processing usually need more. remove non need production amount large parts, mold opening use versus 当不划算. injection molding mold cost can can high 达3万美金. if need certain types parts, that mold opening cost is can 接受, aviation usually one-time need or more less.
 
  显然, substitute/replace parts must same plastics made formed. 不久以 front, aviation manufacturing toward plastics supply provide 原始零部 parts sample use made. in, let plastics engineering 师直接 from CAD design to FAA批准 sample.
 
   aviation use plastics
 
   due to has 如此之 more high property can plastics selection, engineering can is to application selection most 佳 材 material. lower introduction types used for aviation field/area plastics.
 
  迭尔林(polyoxymethylene (POM) resin)—— this type of material can shrink small metal and plastics between 差距, combined resistant creep property, strong/high degree, rigid degree, hardness, dimensional stability and tough property. it anti solvent agent, anti 燃油, wear resistant loss, low abrasion loss, low friction. its basic machine surface property can make bearings can in degree abrasion loss.
 
  Ultem polyetherimide (PEI) —— this is types 无定形 thermoplastic property polyetherimide (PEI) (PEI)材 material, combined mechanical properties, thermal properties and electrical properties. its machine strong/high degree, heat resistant property, corrosion resistant property and other features, and easy processing and surface treatment, let its can used for many aviation aerospace application.
 
   polycarbonate (PC) —— this is types resistant use high property can plastics, it very easy processing, can provide color heat resistant property, and due to its transparent degree is optical parts 首选. it is types high strength material, impact strong/high degree is pressure force 25倍.
 
   polyether ether ketone (PEEK)—— this is types tool strong/high degree, rigid degree, hardness polymer, for/regarding and high temperature, high wet and heavy negative application is types selection. polyether ether ketone melt combined resistant abrasion loss, chemical resistance and resistant wet property and strong/high degree and rigid degree. it also 显示出良 good scratch property can and wear resistance. it provide hydrolysis resistant property, can in high pressure water and in very long time, 也不会出现严 heavy degradation. due to its high temperature resistance property, processing temperature degree ultra- 常规 plastics can 承受 极限时, polyether ether ketone will is types selection.

   aviation plastics parts application 广泛
 
   nylon (Nylon)——一 types core material, main/primary is due to its tough property and strong/high degree. it wear resistant loss, tool has good wear resistance. it very easy processing, light 巧, but also tool has high cost 效益. due to its color wear resistance, can substitute/replace metal, 橡胶以 and other material parts.
 
   ultra-high molecular weight (UHMW)材 material ——当 engineering need improve/increase equipment efficiency, improve/increase its wear resistance, drop property can 时, selection ultra-high molecular weight polyethylene (PE) made as plastics parts. UHMW也 provide excellent property can, temperature degree, impact resistant, resistant abrasion loss. it tool has ratio or aluminum more low friction coefficient.
 
   PTFE (Teflon)—— this is types carbon fluorine combined material, can very good used for from high temperature and chemical ring to need high pure degree and inert property 方. it can in scope/range temperature degree and high negative lower maintain its property can, in aviation industrial in, it usually used for and chemical resistance application.
 
   polysulfone (PSU) (Polysulfone)—— this type of material tool has high heat stabilized property, made formed parts in negative and high temperature lower can maintain stability and resistant creep and resistant deformation. it tool has high tensile strength, and temperature degree rise high, flexural modulus still very high. polysulfone (PSU) is high degree resistant machine acid water solvent liquid and oxidation agent, but also make in high temperature and degree pressure water lower, it still can resistant many non property solvent agent.
 
  随 aviation aerospace industrial development, plastics and its application 也随之 development. due to plastics tool has comprehensive property can, and plastics new material in development, has versus plastics will in aviation aerospace industrial innovation in key/critical function.
