Pulojekiti ya European RECOTRANS yatsimikizira kuti mu njira zosinthira utomoni (RTM) ndi pultrusion, ma microwave angagwiritsidwe ntchito kukonza njira yophikira zinthu zophatikizika kuti achepetse kugwiritsa ntchito mphamvu ndikufupikitsa nthawi yopangira, komanso kuthandizira kupanga zinthu zabwino kwambiri. Pulojekitiyi yatsimikiziranso kuti ukadaulo wa laser ungagwiritsidwe ntchito kupeza mgwirizano wodalirika pakati pa zinthu zophatikizika ndi chitsulo, zomwe zimatha kuchotsa malo olumikizirana omwe amawonjezera kulemera kwa kapangidwe kake.
Kudzera mu kuphatikiza ukadaulo wa microwave ndi laser welding, pulojekiti ya RECOTRANS yapanga zinthu zatsopano zopangidwa ndi thermoplastic composite ndipo yazigwiritsa ntchito popanga zigawo zatsopano, potero ikuphunziranso momwe zinthu zopangidwa ndi thermoplastic composite izi zingagwiritsidwirenso ntchito.
Kugwiritsa ntchito microwave ndi laser welding kuti mupeze zinthu zobwezerezedwanso za thermoplastic composite zoyenera makampani oyendetsa katundu
Pogwiritsa ntchito ukadaulo wopangira zinthu zomwe si zachikhalidwe monga ma microwave radiation ndi laser welding mu resin transfer molding (RTM) ndi pultrusion production liners, pulojekiti ya RECOTRANS yapeza zinthu zotsika mtengo komanso zobwezerezedwanso zoyenera makampani oyendetsa katundu omwe ali ndi zokolola zambiri. Zipangizo zophatikizana zamakina azinthu zambiri. Poyerekeza ndi zipangizo zophatikizana zomwe zikugwiritsidwa ntchito pano, zipangizo zophatikizana zamakina azinthu zambirizi zimachepetsa ndalama ndi kugwiritsa ntchito mphamvu chifukwa cha liwiro la pultrusion la 2m/min komanso liwiro la RTM cycle la mphindi 2 (nthawi ya polymerization imachepetsedwa ndi 50%).
Pulojekiti ya RECOTRANS yatsimikizira zotsatirazi zomwe zili pamwambapa popanga zitsanzo zitatu zenizeni, kuphatikizapo:
Mu njira ya RTM, zinthu zopangidwa ndi thermoplastic zopangidwa ndi ulusi wagalasi ndi thermoplastic acrylic resin zimapezeka pophatikiza ukadaulo wa microwave. Nthawi yomweyo, kuwotcherera kwa laser kumagwiritsidwa ntchito kuzindikira kulumikizana pakati pa zinthu zopangidwa ndi chitsulo ndi chitsulo. Mwanjira imeneyi, zimapangidwa magalimoto akuluakulu. Zitsanzo za zigawo za makina oimika kumbuyo kwa cockpit.
Mu ndondomeko ya c-RTM, zinthu zopangidwa ndi thermoplastic zopangidwa ndi zinthu zolimbikitsidwa ndi ulusi wa kaboni ndi utomoni wa acrylic wa thermoplastic zimapezeka pophatikiza ukadaulo wa microwave, potero kupanga mapanelo a zitseko zamagalimoto.
Mu ndondomeko ya pultrusion, zinthu zopangidwa ndi ulusi wagalasi wolimbikitsidwa ndi ulusi ndi thermoplastic acrylic resin zimapezeka kudzera mu kuphatikiza ukadaulo wa microwave, motero kupanga gulu lamkati la makampani oyendetsa sitima, zinthu zopangidwa ndi ulusi ndi laser. Kulumikizana pakati pa zitsulo kumachitika ndi kuwotcherera.
Kuphatikiza apo, pulojekitiyi imagwiritsanso ntchito zipangizo zobwezerezedwanso 50% popanga gawo lowonetsera chogwirira cha chitseko kuti zitsimikizire kuti zinthu zatsopano zopangidwa ndi thermoplastic composite zomwe zapangidwa kudzera mu ukadaulo wa microwave ndi laser welding zingagwiritsidwenso ntchito.
