Iphrojekthi ye-European RECOTRANS ifakazele ukuthi ku-resin transfer molding (RTM) kanye nezinqubo ze-pultrusion, ama-microwaves angasetshenziswa ukuthuthukisa inqubo yokuphulukisa yezinto ezihlanganisiwe ukunciphisa ukusetshenziswa kwamandla kanye nokunciphisa isikhathi sokukhiqiza, kuyilapho esiza ukukhiqiza ikhwalithi engcono Umkhiqizo.Le phrojekthi iphinde yafakazela ukuthi ubuchwepheshe be-laser bungasetshenziswa ukufeza ukuxhumana okuthembekile phakathi kwezinto ezihlanganisiwe nensimbi, okungaqeda amalunga ahlanganisiwe akhulisa isisindo sesakhiwo.
Ngokuhlanganiswa kobuchwepheshe bokushisela i-microwave ne-laser, iphrojekthi ye-RECOTRANS isungule into entsha eyinhlanganisela ye-thermoplastic futhi yayisebenzisa ukwenza izingxenye ezintsha, ngaleyo ndlela icwaninga nokuphinda kusetshenziswe kabusha kwale nto eyinhlanganisela ye-thermoplastic.
Ukusebenzisa i-microwave ne-laser welding ukuthola izinto eziyinhlanganisela ze-thermoplastic ezilungele imboni yezokuthutha
Ukuhlanganisa ubuchwepheshe bokukhiqiza obungewona abendabuko obufana nemisebe ye-microwave kanye ne-laser welding ekubunjweni kokudluliswa kwe-resin yamanje (RTM) kanye nemigqa yokukhiqiza i-pultrusion, iphrojekthi ye-RECOTRANS ithole imikhiqizo engabizi kakhulu futhi egaywa kabusha efanele imboni yezokuthutha enesivuno esikhulu.Izinto ezihlanganisiwe zesistimu yezinto eziningi.Uma kuqhathaniswa nezinto ezihlanganisiwe ezisetshenziswa njengamanje, lolu hlelo oluhlanganisiwe lwezinto ezibonakalayo lunciphisa izindleko kanye nokusetshenziswa kwamandla ngenxa yesivinini se-pultrusion se-2m / min kanye nesilinganiso somjikelezo we-RTM we-2min (isikhathi se-polymerization sincishiswa ngo-50%).
Iphrojekthi ye-RECOTRANS iqinisekise imiphumela engenhla ngokukhiqiza amasampula okubonisa osayizi bangempela aba-3, okuhlanganisa:
Enqubweni ye-RTM, i-thermoplastic composite material eyenziwe nge-glass fiber kanye ne-thermoplastic acrylic resin itholakala ngokuhlanganisa ubuchwepheshe be-microwave.Ngasikhathi sinye, i-laser welding isetshenziselwa ukubona ukuxhumana phakathi kwezinto eziyinhlanganisela nensimbi.Ngale ndlela, ikhiqizwa amaloli.Izingxenye zesampula zesistimu yokumiswa yangemuva kwe-cockpit.
Enqubweni ye-c-RTM, i-thermoplastic composite material eyenziwe ngezinto eziqiniswe nge-carbon fiber kanye ne-thermoplastic acrylic resin itholakala ngokuhlanganisa ubuchwepheshe be-microwave, ngaleyo ndlela ikhiqize amaphaneli eminyango yemoto.
Enqubweni ye-pultrusion, into eyinhlanganisela eyenziwe ngezinto eziqinisiwe ze-glass fibre kanye ne-thermoplastic acrylic resin itholakala ngokuhlanganiswa kobuchwepheshe be-microwave, ngaleyo ndlela ikhiqize iphaneli yangaphakathi yemboni yezokuthutha ngojantshi, izinto eziyinhlanganisela kanye nokuxhumana phakathi kwezinsimbi kuzuzwa nge-laser. ukushisela.
Ukwengeza, iphrojekthi iphinde isebenzise u-50% wezinto ezigaywe kabusha ukwenza ingxenye yokubonisa isibambo somnyango ukuze kuqinisekiswe ukugaywa kabusha kwezinto ezihlanganisiwe ze-thermoplastic ezithuthukiswe ngobuchwepheshe be-microwave ne-laser welding.
