Intambwe mpuzamahanga yo gushyira amashanyarazi mu bwikorezi no kunoza imikorere mu by’indege irimo gutuma habaho icyifuzo kidasubirwaho cy’ibikoresho bishya bikora neza. Guhera mu 2025, polimeri zigezweho n’ibinyabutabire bikomejwe byarenze inshingano zabyo gakondo nk’ibice byo kwisiga cyangwa ibitari imiterere, ubu ni byo by’ingenzi muri izi mpinduka z’ubuhanga. Mu isoko ry’ibinyabiziga bikoresha amashanyarazi (EV) rihanganye cyane ndetse n’urwego rw’indege rukoresha ikoranabuhanga rigezweho, izi plastiki zoroshye, zikomeye kandi zifite imikorere myinshi ntizikiri ubundi buryo bwo gusimbura icyuma gusa; ni ikoranabuhanga rituma habaho ubushobozi. Kuva ku gutanga imiterere myiza kugeza ku gucunga ubushyuhe bukabije no kwemeza umutekano w’amashanyarazi ufite ingufu nyinshi, polimeri zigezweho zikemura ibibazo bikomeye cyane kandi zigena imikorere y’ingendo za none.

Ikibazo cy'ingenzi mu miterere ya EV n'indege ni ukurwanya uburemere. Kuri EV, buri kilo gitanzwe gisobanura ko bateri yiyongereye, ikintu cy'ingenzi mu kwemerwa n'abaguzi. Ku ndege, uburemere buke bivuze kugabanuka kw'ikoreshwa rya lisansi no kwiyongera k'ubushobozi bwo gutwara. Nubwo ibyuma nka aluminiyumu na titaniyumu ari byo bikoresho byatoranijwe, birimo kugera ku bushobozi bwabyo bwo koroshya kandi akenshi bizana uburyo bugoye bwo gutunganya no kugabanya ibiciro. Ibi byatanze amahirwe menshi ku bikoresho bya polymer kugira ngo byinjiremo, bitanga imbaraga zingana cyangwa ndetse n'ubukana buhanitse ku rugero ruto rw'ubucucike.

Ariko uruhare rwa pulasitiki muri iki gihe rurenze kure kugabanya ibiro byoroshye. Mu rwego rwa EV, ni ingenzi mu gucunga ubushyuhe bwa batiri, gukingira amashanyarazi kuri sisitemu zifite ingufu nyinshi, no guhuza ibikoresho by'ikoranabuhanga bigoye. Mu kirere, zitanga ubushobozi bwo kurwanya umunaniro udasanzwe, ubwisanzure mu gushushanya imiterere ikomeye y'ikirere, no kwirinda ingese. Iyi mikorere myinshi niho polymer zikora neza cyane, zemerera injeniyeri guhuza ibice, kugabanya ubukana bw'iteraniro, no kubaka imodoka nziza kandi zikora neza.

Imodoka y'amashanyarazi: Icyerekezo cy'udushya twa polymer

Imodoka igezweho ikoresha amashanyarazi ni igihamya cy'uburyo pulasitiki igezweho ikora kandi ikaba ari ingenzi cyane. Imikoreshereze yayo igera ku modoka yose, kuva kuri bateri kugeza kuri chassis na powertrain.

1. Udukingirizo twa Bateri: Igihome cya Polimeri:Bateri ni umutima wa EV, kandi uruziga rwayo ni imwe mu mashini zisaba cyane ibikoresho byose. Igomba kuba ikomeye mu miterere yayo kugira ngo irinde uturemangingo ku ngaruka, ifunze neza, itange ubushobozi bwo kwirinda umuriro mu gihe ubushyuhe burenze, kandi icunge uburyo bwo guhangana n’umuriro (EMI). Nubwo imiterere ya mbere yakundaga gukoresha aluminiyumu, polymer igizwe na fibre reinforced polymer irimo kuba igisubizo cy’amahitamo. Thermosets na thermoplastics zikozwe mu kirahuri, fibre na carbon-fibre bishobora guhindurwamo inyubako zigoye, zifite igice kimwe cyoroshye kurusha ibyuma. Izi composites zitanga ubushobozi bwo kudahungabana no kudahangana n’ingaruka. Icy’ingenzi ni uko zishobora gukorwa hamwe n’inyongera zidasanzwe kugira ngo zihuze n’amahame akomeye ya UL 94 V-0 yo kudakoresha umuriro kandi zishobora kugira ibyuma bihuza kugira ngo bitange uburinzi bwa EMI, bihuza imikorere myinshi mu gice kimwe cyabumbwe.

2. Sisitemu zifite ingufu nyinshi: Umutekano w'ubushyuhe:Imashini zitwara umuriro zikora ku muvuduko wa 400V, 800V, cyangwa urenzeho, bigatuma hakenerwa cyane ubushyuhe bw'amashanyarazi kugira ngo umutekano ube mwiza. Aha ni ahantu pulasitiki irusha ibyuma. Imashini zikora neza nka Polyamide (PA), Polybutylene Terephthalate (PBT), na Polyphenylene Sulfide (PPS) zikoreshwa mu gukora ibikoresho byinshi bifite ingufu nyinshi, harimo n'ibihuza, ibyuma bitanga umuriro, n'ibikoresho bikwirakwiza ingufu. Ibi bikoresho bitoranywa hashingiwe ku gipimo cyabyo cyo gupima ubushyuhe (CTI), igipimo cy'uko birwanya kwangirika kw'amashanyarazi. Ibara ry'icunga ryiza ry'ibi bice, riteganywa n'amahame y'umutekano, ryabaye ikimenyetso cy'ikoranabuhanga rya EV powertrain, byose bifashishwa n'imiterere yizewe yo gukingira polymer.

3. Gucunga ubushyuhe: Gukonjesha mu gihe cy'umuvuduko:Gucunga ubushyuhe buturuka kuri bateri mu gihe cyo gusharija vuba no gusohora umuriro mwinshi ni ingenzi cyane ku mikorere yayo no ku gihe cyayo. Plasitiki igira uruhare runini mu gushyiraho uburyo bugezweho bwo gucunga ubushyuhe. Polima zitwara umuriro mu buryo bushyushye, zuzuyemo ibikoresho nka boron nitride cyangwa grafiti, zikoreshwa mu gukora amasahani yo gukonjesha, aho gushyushya, n'aho gukonjesha ibikoresho by'ikoranabuhanga byoroheje. Ibi bikoresho bishobora gushyirwa mu buryo bugoranye cyane, bigatuma habaho imiyoboro igoye yo gukonjesha idashoboka cyangwa ihenze cyane gukora hakoreshejwe icyuma cyangwa gusukamo. Ibi bituma habaho uburyo bwiza bwo gukwirakwiza ubushyuhe, ikintu cy'ingenzi mu gutuma ubushobozi bwo gusharija bwihuta cyane.

Ibyerekeye Ijuru: Guteza imbere imipaka y'imikorere n'imikorere myiza

Mu nganda z’indege, aho buri garama igenzurwa kandi amahame y’imikorere akaba ari ntakuka, polymer composites zabaye imbaraga zihindura ibintu mu myaka ibarirwa muri za mirongo, kandi uruhare rwazo rukomeje kwaguka.

Ingendo z'indege zigezweho z'ubucuruzi nka Boeing 787 Dreamliner na Airbus A350 ni ingero nziza. Hejuru ya 50% by'uburemere bwazo bugizwe na pulasitiki ikoreshwa mu byuma bya karuboni (CFRP). Ibi bikoresho bikoreshwa mu gukora ibice by'inyuma, amababa, n'inyuma. Inyungu zabyo ni nyinshi: kugabanuka gukomeye k'uburemere muri rusange, bigatuma lisansi ikoreshwa neza izamukaho 20-25% ugereranije n'indege za aluminiyumu zo mu gihe cyashize. Byongeye kandi, CFRP ntizigwa, ibi bigabanya ibisabwa mu kubungabunga igihe kirekire. Zitanga kandi ubushobozi bwo kwihanganira umunaniro mwinshi, bigatuma umuvuduko n'ubushuhe byinshi mu cyumba, bivamo uburambe bwiza ku mugenzi.

Uburyo bwo gukora izi nyubako nini cyane zivanze nabwo burimo gutera imbere. Roboti zikoresha Fiber Placement (AFP) na Automated Tape Laying (ATL) ubu zishobora gushyira hasi ibikoresho bivanze ku muvuduko utangaje no ku buryo bunoze, bigatuma gukorwa kw'inyubako nini, ntoya, bishoboka.

Uretse imiterere y'ikirere, imbere mu ndege hakozwe hafi ya hose muri polymeri zifite imikorere myiza zigomba kubahiriza amabwiriza akomeye y'umuriro, umwotsi n'uburozi (FST). Ibikoresho nka PEI (Polyetherimide, urugero, ULTEM) n'imiterere myiza ya polycarbonate bikoreshwa mu kwicara, mu bisanduku byo hejuru, no ku mpande. Ibi bikoresho bihuza imiterere yoroheje n'umutekano udasanzwe w'umuriro no kuramba, byose ni ingenzi ku bidukikije by'indege.

Umupaka w'Inganda: Kuziba Icyuho kiri hagati y'Imikorere n'Umusaruro

Imbogamizi nyamukuru ku bikoresho bigezweho bya kera ni umuvuduko n'ikiguzi cy'inganda. Ariko, udushya twinshi turimo kuziba iki cyuho. Iterambere rya thermoplastics zikora neza cyane, bitandukanye na thermoset zisanzwe, ni ikintu cy'ingenzi gikunze kugaragara. Thermoplastics zishobora gutunganywa vuba cyane hakoreshejwe uburyo nka injection overmolding na compression molding, kandi zitanga inyungu yo kongera gukoreshwa. Ibi bituma zirushaho gukurura abantu bakoresha imodoka nyinshi.

Ubuhanga nko gukoresha ibikoresho byinshi mu gusya, bushobora guhuza imiterere ikomeye hamwe na elastomer yoroshye kandi yoroshye ya thermoplastic (TPE) mu gice kimwe, burimo gutuma habaho imikorere idasanzwe. Igice kimwe cyabumbwe ubu gishobora gutanga inkunga y'imiterere, gasket ifunze, n'ubuso bworoshye bwo gukoraho, bigabanya cyane umubare w'ibice, uburemere, n'igihe cyo guteranya.

Mu gusoza, polimeri zigezweho n'ibinyabutabire ni moteri zidakoresha ikoranabuhanga ziyobora ahazaza ho kugenda. Ubushobozi bwazo bwihariye bwo gutanga uruvange rw'uburemere buke, imbaraga nyinshi, imicungire y'ubushyuhe, ubushyuhe bw'amashanyarazi, n'ubwisanzure mu gushushanya bituma ziba igikoresho cy'ingenzi ku bahanga mu by'amashanyarazi n'iby'indege. Uko ubumenyi bw'ibikoresho n'ikoranabuhanga ryo gutunganya ibintu bikomeza gutera imbere, uruhare rw'izi polimeri ruzagenda rwaguka gusa, rugire uruhare mu gutuma imodoka zoroshye, zitekanye kandi zikora neza ku butaka no mu kirere.
