Ii-composites zineengenelo ezininzi xa zithelekiswa nezinto zesiqhelo. Enye yeenzuzo kukuba lula kwaye zihlala ixesha elide xa kulungiswa. Iindawo ezidityanisiweyo ezonakeleyo zinokutshintshwa ukuba akukho lwazi malunga nokulungiswa. Kodwa eneneni iindawo ezidityanisiweyo kulula ukuzilungisa kunezixhobo zesiqhelo. Kweli nqaku siza kubonelela ngokuqonda okusisiseko malunga nokulungiswa kwezinto ezidityanisiweyo.
Ukulungiswa okuphumelelayo kwe-composite kusenza sikwazi ukwandisa ubomi benxalenye kwaye songe iindleko zokutshintsha inxalenye ye-composite. Kukho imigaqo emithathu ephambili ekufuneka iqondwe ukuba ufuna ukugqiba ukulungiswa kwe-composite ngempumelelo. Le yi-Repair Eyahlukileyo kwi-Original Part, Ukwanda koMphezulu woMphezulu kwandisa amandla okulungiswa kwe-Composite, Ukulungiswa kufuneka kuhambelane ne-Original Part yakho.
Ukulungiswa Kwahlukile Kwinxalenye Yokuqala.
Umgaqo wokuqala malunga nokulungiswa kwe-composite ekufuneka iqondwe kukuba ukulungiswa kwesakhiwo kwenziwa ngenkqubo eyahlukileyo kuneyokuqala. Xa inxalenye edibeneyo yenziwe okokuqala, i-resin yayo iyaphilisa ukubopha ngokweekhemikhali nangokwasemzimbeni ngelaphu lokuqinisa nto leyo ebangela iyunithi enye, nokuba inani okanye ukujongwa kwe-plies yelaphu kunjani na. Oku kubizwa ngokuba yisakhiwo okanye i-bond eyintloko, kwaye lolona hlobo luqinileyo lwe-bond olunokubakho ngaphakathi kwenxalenye edibeneyo.
Nje ukuba inxalenye yonakele, zonke izinto ezilungisiweyo ziba ziibhondi zesibini ezinamathele kwisakhiwo sokuqala esiphambili. Oku kuthetha ukuba zonke izinto ezilungisiweyo zixhomekeke ekubotshelelweni ngokwasemzimbeni kumphezulu wesakhiwo sokuqala esiphambili. Ngenxa yesi sizathu, ukulungiswa kwefiberglass kuxhomekeke kumgangatho wokuncamathelisa we-resin yabo ukuze kufumaneke amandla—amandla okunamathela ngokwasemzimbeni kwisakhiwo sokuqala. Ngenxa yesi sizathu, i-resin esetyenziselwa ukulungiswa kufuneka ibe namandla afanayo ne-resin esetyenziselwa ukwenza loo nxalenye. Enyanisweni, ii-resin ezineempawu zokuncamathelisa ezinamandla ngamanye amaxesha zisetyenziselwa ukulungiswa.
Ukwanda Komphezulu Wonyusa Amandla Okulungiswa Kwezinto Ezihlanganisiweyo
Ekubeni ukulungiswa kwefiberglass kuxhomekeke ekunamatheleni komphezulu (ukubophelela ngokwasemzimbeni) kokulungiswa kwesakhiwo esiphambili, ukwandisa indawo yomphezulu womgca webhondi kuya kwandisa amandla kunye nokuqina kwebhondi—kwaye ngokwandisa inxalenye okanye ukulungiswa.
Ngokwesiqhelo, indlela esetyenziswayo ukwandisa indawo yomphezulu kukugquma okanye ukugquma isikhafu. Olu hlobo lokugquma luthetha ukuba indawo esecaleni komonakalo igqunywa kancinci kancinci, nto leyo ebangela ukuba kubekho malunga ne-½—¾ ye-intshi yendawo nge-ply ye-composite laminate. Ukugquma isikhafu kudla ngokwenziwa nge-high speed compressed air power sander kunye ne-iidiski zokusila ze-roloc.
Ekubeni uninzi lwezakhiwo ezidityanisiweyo zincinci kakhulu, le yinkqubo ethambileyo. Ubungakanani be-taper, xa kuthelekiswa nobukhulu be-laminate, buchazwa njengomlinganiselo. Ngokubanzi, ukuba kufuneka ukulungiswa kube namandla okanye kubaluleke ngakumbi, kokukhona umlinganiselo umkhulu. Ukulungiswa kwesakhiwo kudla ngokufuna i-taper ethambileyo, enomlinganiselo we-20:1 ukuya kwi-100:1.
Enye indlela esetyenziswayo ukwandisa indawo yomphezulu kukugquma ngesanti. Le nkqubo ichaza ubungakanani bokulungiswa kwangaphakathi, ize isuse izinto ezijikelezileyo kububanzi be ½” nge ply nganye yenxalenye, isebenzele kumphezulu wenxalenye. Oku kubangela ukukhula okukhulu komphezulu wokulungisa kwaye kuvumela ukuba i-fiber ibonakale kwinqanaba ngalinye.
Zombini ezi ndlela zamkelekile kwiindlela ezininzi zokulungisa izinto ezidityanisiweyo, nangona uninzi lubona ukuba ukugquma i-scarf kulula, kwaye ngokubanzi kuthathwa njengokungcono. Ukugquma kuphumela kwimiphetho ekhawulezileyo kunye namalungu empundu kwi-ply nganye elungisiweyo. Kunzima nokugquma isanti ngaphandle kokunqumla, nto leyo enokonakalisa ii-plies ezingaphantsi.
Ukulungiswa kufanele kuhambelane nenxalenye yakho yokuqala
Nangona ukulungiswa kwakho okudityanisiweyo kwahlukile kwinxalenye yakho yokuqala, kuyacetyiswa ukuba uphinde ubukhulu, uxinano, kunye nokujonga i-ply ye-laminate yokuqala xa ulungisa. Oku kuya kunceda ukugcina ukusebenza kwenxalenye. Okungakumbi akusoloko kungcono—kule meko, ukuba ukulungiswa kwakho kukhulu kunenxalenye yokuqala, ngokuqinisekileyo kuya kuba nzima, nokuba yintoni na into esetyenziswayo. Ukufaka amandla ahlukeneyo kwinxalenye kunokubangela iindawo zoxinzelelo ezingalindelekanga, ekugqibeleni kukhokelele ekudinweni kwezinto okanye ukungaphumeleli. Kungcono ukutshintsha ngononophelo yonke i-ply esusiweyo kwindawo eyonakeleyo ngezinto ezifanayo, ezibekwe kwindawo efanayo xa kunokwenzeka. Le ndlela yokutshintsha i-ply—for—ply iqinisekisa ukuba isakhiwo esilungisiweyo sinokumelana nemithwalo efanayo neyeyokuqala, kwaye siya kuyisasaza imithwalo njengoko bekucetyiwe.
