I-Carbon FiberInqanawa yoXinzelelo oluQokelelweyo oluQokelelweyo sisitya esincinci esinodonga oluncinci esiqulathe i-liner evalwe kakuhle kunye nomaleko we-fiber-wound onamandla aphezulu, owenziwa ikakhulu yinkqubo yokubopha kunye nokuluka i-fiber. Xa kuthelekiswa nemikhumbi yoxinzelelo lwesinyithi yendabuko, i-liner yemikhumbi yoxinzelelo oluqokelelweyo isebenza njengendawo yokugcina, ukuvala kunye nokukhusela ukugqwala kweekhemikhali, kwaye umaleko oqokelelweyo usetyenziselwa ikakhulu ukuthwala umthwalo woxinzelelo lwangaphakathi. Ngenxa yamandla aphezulu athile kunye nokuyilwa kakuhle kwezixhobo ezidityanisiweyo, imikhumbi yoxinzelelo oluqokelelweyo ayiphuculanga kakhulu kuphela umthamo wayo wokuthwala umthwalo, kodwa ikwanciphise kakhulu ubunzima benqanawa xa kuthelekiswa nemikhumbi yoxinzelelo lwesinyithi yendabuko.
Umaleko wangaphakathi wesitya soxinzelelo lwe-fiber-wound ikakhulu sisakhiwo se-liner, esimsebenzi waso oyintloko kukusebenza njengomqobo wokuvala ukuthintela ukuvuza kweegesi ezinoxinzelelo oluphezulu okanye ulwelo olugcinwe ngaphakathi, kwaye kwangaxeshanye ukukhusela umaleko wangaphandle we-fiber-wound. Olu maleko aluyi kubola zizinto ezigcinwe ngaphakathi kwaye umaleko wangaphandle ngumaleko we-fiber-wound oqiniswe nge-resin matrix, esetyenziswa kakhulu ukumelana nemithwalo emininzi yoxinzelelo kwisitya soxinzelelo.
1. Ulwakhiwo lwemithambo yoxinzelelo lwe-fiber-wound
Kukho iintlobo ezine eziphambili zezakhiwo zemithambo yoxinzelelo edityanisiweyo: isilinda, ingqukuva, i-annular kunye nengxande. Isitya esingqukuva sinecandelo lesilinda kunye neentloko ezimbini. Imithambo yoxinzelelo lwesinyithi yenziwe ibe ziimo ezilula kunye namandla agqithisileyo kwicala le-axial. Imithambo engqukuva inexinzelelo olulinganayo kwizikhokelo ze-warp kunye ne-weft phantsi koxinzelelo lwangaphakathi kwaye zisiqingatha soxinzelelo olujikelezayo lwemithambo engqukuva. Amandla ezinto zesinyithi alingana kuzo zonke iindlela, ngoko ke isitya esingqukuva esenziwe ngesinyithi senzelwe amandla alinganayo, kwaye sinobunzima obuncinci xa umthamo kunye noxinzelelo ziqinisekile. Imeko yamandla esitya esingqukuva yeyona ifanelekileyo, udonga lwesitya lunokwenziwa lube lolona luncinci. Nangona kunjalo, ngenxa yobunzima obukhulu bokwenza izikhongozeli ezingqukuva, ngokubanzi zisetyenziswa kuphela kwizithuthi zasemoyeni nakwezinye iziganeko ezikhethekileyo. Isitya esirhangqiweyo kwimveliso yemizi-mveliso sinqabile kakhulu, kodwa kwezinye iimeko ezithile okanye kufuneka esi sakhiwo, umzekelo, izithuthi zasemoyeni ukuze zisebenzise ngokupheleleyo indawo elinganiselweyo, ziya kusebenzisa esi sakhiwo sikhethekileyo. Isikhongozeli esingunxande senzelwe ukujongana ikakhulu xa indawo incinci, ukusetyenziswa kwendawo kunye nokusetyenziswa kwezakhiwo, njengeemoto zeetanki ezingxande, iimoto zeetanki zikaloliwe, njl.njl., ezo zikhongozeli zihlala zizikhongozeli ezinoxinzelelo oluphantsi okanye izikhongozeli zoxinzelelo lomoya kwaye iimfuno zomgangatho wesibane zingcono.
Ubunzima besakhiwo sei-compositeisitsha soxinzelelo ngokwaso, utshintsho olukhawulezileyo lobukhulu bentloko nentloko, ubukhulu obuguquguqukayo kunye ne-engile yentloko, njl.njl., zizisa ubunzima obuninzi kuyilo, uhlalutyo, ukubala kunye nokubumba. Ngamanye amaxesha, izitya zoxinzelelo ezidityanisiweyo azidingi nje kuphela ukugoba kwii-engile ezahlukeneyo kunye nomlinganiselo wesantya oguquguqukayo kwicandelo lentloko, kodwa kufuneka zisebenzise iindlela ezahlukeneyo zokugoba ngokwezakhiwo ezahlukeneyo. Kwangaxeshanye, impembelelo yezinto ezisebenzayo ezifana ne-friction coefficient kufuneka iqwalaselwe. Ke ngoko, uyilo lwesakhiwo oluchanekileyo nolufanelekileyo kuphela olunokukhokela ngokuchanekileyo inkqubo yokuvelisa ukugoba kwezitya zoxinzelelo ezidityanisiweyo, ukuze kuveliswe iimveliso zesitya soxinzelelo esidityanisiweyo esikhaphukhaphu esihlangabezana neemfuno zoyilo.
2. Izinto ezisetyenziswa kwisitya soxinzelelo lwe-fiber-wound
Njengenxalenye ephambili ethwala umthwalo, umaleko wokujika ifayibha kufuneka ube namandla aphezulu, imodulus ephezulu, uxinano oluphantsi, uzinzo lobushushu kunye nokufuma okuhle kweresin, kunye nokujika kakuhle kunye nokuqina okufanayo kwefayibha. Iifayibha zokuqinisa ezisetyenziswa rhoqo kwimikhumbi yoxinzelelo oludityanisiweyo olukhaphukhaphu ziqukaiifayibha zekhabhoni, iifayibha ze-PBO,iifayibha ze-polyamine ezinuka kamnandikunye neefayibha ze-UHMWPE.
