Iphrojekthi ye-European RECOTRANS ifakazele ukuthi ezinqubweni zokudlulisa i-resin (RTM) kanye ne-pultrusion, ama-microwave angasetshenziswa ukwenza ngcono inqubo yokwelapha izinto ezihlanganisiwe ukuze kuncishiswe ukusetshenziswa kwamandla futhi kufinyezwe isikhathi sokukhiqiza, kuyilapho kusiza nasekukhiqizeni umkhiqizo osezingeni eliphezulu. Iphrojekthi iphinde yafakazela ukuthi ubuchwepheshe be-laser bungasetshenziswa ukufeza ukuxhumana okuthembekile phakathi kwezinto ezihlanganisiwe nensimbi, okungasusa amalunga ahlanganisiwe akhulisa isisindo sesakhiwo.
Ngokuhlanganisa ubuchwepheshe bokushisela nge-microwave kanye ne-laser, iphrojekthi ye-RECOTRANS ithuthukise izinto ezintsha ezihlanganisiwe ze-thermoplastic futhi yazisebenzisa ukwenza izingxenye ezintsha, ngaleyo ndlela ifunda nokusebenziseka kabusha kwalezi zinto ezihlanganisiwe ze-thermoplastic.
Ukusebenzisa i-microwave kanye ne-laser welding ukuthola izinto ezihlanganisiwe ze-thermoplastic ezingasetshenziswa kabusha ezifanele imboni yezokuthutha
Ngokuhlanganisa ubuchwepheshe bokukhiqiza obungebona obendabuko njengokukhanya kwe-microwave kanye nokushisela nge-laser emigqeni yokukhiqiza ye-resin transfer molding (RTM) kanye ne-pultrusion, iphrojekthi ye-RECOTRANS ithole imikhiqizo engabizi kakhulu futhi engasetshenziswa kabusha efanele imboni yezokuthutha enezinzuzo eziphezulu. Izinto ezihlanganisiwe zesistimu yezinto eziningi. Uma kuqhathaniswa nezinto ezihlanganisiwe ezisetshenziswa njengamanje, le nto ehlanganisiwe yesistimu yezinto eziningi inciphisa izindleko kanye nokusetshenziswa kwamandla ngenxa yesivinini se-pultrusion esingu-2m/min kanye nesilinganiso somjikelezo we-RTM esingu-2min (isikhathi se-polymerization sincishiswa ngo-50%).
Iphrojekthi ye-RECOTRANS iqinisekise imiphumela engenhla ngokukhiqiza amasampula amathathu okubonisa ngobukhulu bangempela, okuhlanganisa:
Enqubweni ye-RTM, izinto ezihlanganisiwe ze-thermoplastic ezenziwe nge-glass fiber kanye ne-thermoplastic acrylic resin zitholakala ngokuhlanganisa ubuchwepheshe be-microwave. Ngesikhathi esifanayo, ukushisela nge-laser kusetshenziswa ukuqaphela ukuxhumana phakathi kwezinto ezihlanganisiwe nensimbi. Ngale ndlela, kukhiqizwa amaloli. Izingxenye zesampula zesistimu yokumiswa kwangemuva kwe-cockpit.
Enqubweni ye-c-RTM, izinto ezihlanganisiwe ze-thermoplastic ezenziwe ngezinto eziqiniswe nge-carbon fiber kanye ne-thermoplastic acrylic resin zitholakala ngokuhlanganisa ubuchwepheshe be-microwave, ngaleyo ndlela kukhiqizwe amaphaneli eminyango yezimoto.
Enqubweni ye-pultrusion, kutholakala izinto ezihlanganisiwe ezenziwe ngezinto eziqiniswe ngefayibha yengilazi kanye ne-thermoplastic acrylic resin ngokuhlanganiswa kobuchwepheshe be-microwave, ngaleyo ndlela kukhiqizwe iphaneli yangaphakathi yemboni yezokuthutha yesitimela, izinto ezihlanganisiwe kanye nokuxhumana phakathi kwezinsimbi kufezwa ngokushisela nge-laser.
Ngaphezu kwalokho, lo msebenzi uphinde usebenzise izinto ezisetshenziswe kabusha ezingama-50% ukwenza ingxenye yokubonisa isibambo somnyango ukuqinisekisa ukuthi izinto ezintsha ezihlanganisiwe ze-thermoplastic ezakhiwe ngobuchwepheshe be-microwave kanye ne-laser welding ziyasebenziseka futhi.
