Njengento evelele yezinhlelo zokusebenza ze-aerospace zesikhathi esizayo, izinto ezihlanganisiwe ze-thermoplastic ezithuthukisiwe okwamanje zibangela uchungechunge lwemisebenzi phakathi kwabakhiqizi be-aerospace, abaklami, abakhiqizi bezingxenye, namaphrosesa abumbayo.Ucwaningo nokuthuthukiswa kwezinto ezihlanganisiwe ze-thermoplastic ze-aerospace kuya ngesivinini, futhi izivivinyo eziningi ezibandakanya izinto eziyinhlanganisela ye-thermoplastic ziyaqhubeka.
Ezinye izinkampani ezintsha nazo ziyangena emakethe, zithola iziqu zabahlinzeki kubakhiqizi be-aerospace, futhi ziqinisa amaketanga okuhlinzeka akhona.Izindlela ezintsha zokukhiqiza kusetshenziswa i-thermoplastics ziyathuthukiswa, ziyathuthukiswa futhi zethulwa.Zonke lezi zimpawu zibonisa ukuthi ukusetshenziswa kwezinto ze-thermoplastic esizukulwaneni esilandelayo sezindiza zezentengiselwano kanye nezicelo ezihlobene kuzokwanda kakhulu.
Izinto ezifana nentuthuko ekukhiqizeni, ekubumbeni nasekukhiqizeni izinto ze-thermoplastic zibe yizici eziyinhloko zokutholakala okwandayo kwezinto zokwakha ze-thermoplastic.Kwezinye izinhlelo zokusebenza ze-aerospace, lezi zinto zinezinzuzo ezisobala ngaphezu kwezinsimbi ezifana nepulasitiki ye-thermoset ne-aluminium.Ziphinde zihambisane nezimo ezisafufusa embonini yokukhiqiza i-aerospace, okuhlanganisa ukusheshisa ukuhlangana nokukhiqizwa kwezindiza, kanye nokuthuthukiswa komklamo wezindiza ezihwebayo ezithuthukisiwe.
Ukuhlaziywa kwezinzuzo ze-Thermoplastic Composites for Aerospace
Izinto ezihlanganisiwe ze-aerospace-grade thermoplastic, ezifana ne-carbon fibre reinforced polyether ether ketone (PEEK) kanye ne-polyether ketone ketone (PEKK), zinamathemba okusebenza abanzi endaweni yesimanje ye-aerospace.I-Thermoplastic prepreg ikhiqizwa kumqulu oyinhloko futhi ingaguqulwa ibe yi-slit tape, i-fiber eqoshiwe noma ezinye izinhlobo.Le mikhiqizo ithuthukiswe ukuze kuzuzwe ukusebenza kahle okuphezulu kanye nokukhiqizwa kwezingxenye ezilula.
Ama-thermoplastics e-Aerospace-grade ayisindi, amelana nezinga lokushisa eliphezulu, futhi anokuqina okuphezulu kanye nokumelana nomthelela.Ezinye izici ezibalulekile zifaka:
Ukumuncwa komswakama okuphansi
Ukumelana nokugqoka okuhle kakhulu
Ukumelana okuhle kakhulu nelangabi/ubuthi bentuthu
Ukukhishwa okuphansi kwamakhemikhali aguquguqukayo
I-coefficient yokwandisa umjikelezo oshisayo ophansi
Nakuba uchungechunge lokuhlinzeka lwamapulasitiki asebenzisa i-thermosetting luphelele kakhulu, futhi umlando wokufaka isicelo njengezingxenye zesakhiwo se-aerospace nawo mude, ubuchwepheshe bamuva nje nentuthuko yenqubo kuthuthukisa indawo yokuncintisana yezinto zokwakha ze-thermoplastic.Isibonelo, abakhiqizi kanye namaphrosesa okubumba ngokunemba bathuthukisa ukunemba kwenqubo yokusika nokuguqula ukukhiqiza izinhlobonhlobo ezinkulu zezingxenye eziphambili.
Ama-Thermoplastic nama-thermoset anezici zokusebenza ezifanayo ngokuqhathaniswa, kodwa anomehluko omkhulu ekusetshenzisweni nasekuphatheni izidingo.Nakuba i-thermoplastics idinga amazinga okushisa aphezulu okucubungula kunama-thermosets, angagcinwa ekamelweni lokushisa futhi abe nempilo yeshalofu engenamkhawulo.
Ngokuphambene nalokho, amapulasitiki e-thermosetting kufanele aqandiswe futhi ancibilikiswe ngaphambi kokucubungula ukuze agcine izakhiwo zawo eziwumshini ngesikhathi sokuthutha nokugcinwa.Impilo yeshelufu ebekiwe yama-thermosets, isikhathi esidingekayo sokuncibilika nokubanda, nesidingo sokulandelela isikhathi esiphelele sokuqandisa kanye nesikhathi sokuncibilika, konke okuhlanganisa izindleko ezengeziwe ezingahlangene ne-thermoplastics.
Izinto ze-Thermoplastic nazo zinenzuzo yokuthi zigaywe kabusha.Ngokungafani namapulasitiki e-thermoset, amapulasitiki e-thermoset abhekana nokusabela kwamakhemikhali okungenakulungiseka ngesikhathi sokucubungula futhi awakwazi ukuncibilika.I-Thermoplastics ingacutshungulwa kabusha ngemva kokusetshenziswa, ukuze ama-resin we-thermoplastic nemicu eqinisayo igaywe kabusha noma iphinde isetshenziswe kwezinye izinhlelo zokusebenza.
I-Hebei Yuniu Fiberglass Manufacturing Company Limitedkuyintoumkhiqizi wezinto ezibonakalayo ze-fiberglass onolwazi olungaphezu kweminyaka eyi-10, isipiliyoni sokuthekelisa seminyaka engu-7.
Singabakhiqizi bezinto zokusetshenziswa ze-fiberglass, ezifana ne-fiberglass roving, intambo ye-fiberglass, i-fiberglass eqoshiwe ye-strand mat, imicu eqoshiwe ye-fiberglass, i-fiberglass mat emnyama, i-fiberglass nokwelukiweyo i-roving, indwangu ye-fiberglass, indwangu ye-fiberglass ..Njalo njalo.
Uma kukhona izidingo, sicela usithinte ngokukhululekile.
Sizokwenza konke okusemandleni ethu ukukusiza futhi sikusekele.
