Qhov project European RECOTRANS tau ua pov thawj tias hauv cov txheej txheem hloov pauv resin (RTM) thiab pultrusion, microwaves tuaj yeem siv los ua kom zoo dua cov txheej txheem kho ntawm cov khoom sib xyaw kom txo qis kev siv hluav taws xob thiab luv lub sijhawm tsim khoom, thaum tseem pab tsim cov khoom zoo dua. Qhov project kuj tau ua pov thawj tias cov thev naus laus zis laser tuaj yeem siv los ua kom muaj kev sib txuas zoo ntawm cov khoom sib xyaw thiab hlau, uas tuaj yeem tshem tawm cov pob qij txha riveted uas ua rau qhov hnyav ntawm cov qauv nce.
Los ntawm kev sib xyaw ua ke ntawm microwave thiab laser welding technology, RECOTRANS project tau tsim cov khoom siv thermoplastic composite tshiab thiab siv nws los ua cov khoom tshiab, yog li ntawd kuj kawm txog kev siv rov qab ntawm cov khoom siv thermoplastic composite no.
Siv microwave thiab laser vuam kom tau txais cov khoom siv thermoplastic composite uas siv tau dua tshiab uas tsim nyog rau kev lag luam thauj mus los
Kev koom ua ke cov thev naus laus zis tsim khoom tsis ib txwm muaj xws li microwave hluav taws xob thiab laser vuam rau hauv cov kab tsim khoom siv resin hloov pauv (RTM) thiab pultrusion tam sim no, qhov project RECOTRANS tau txais cov khoom pheej yig thiab rov ua dua tshiab uas tsim nyog rau kev lag luam thauj mus los nrog cov txiaj ntsig siab. Cov ntaub ntawv sib xyaw ua ke ntawm ntau yam khoom. Piv nrog cov ntaub ntawv sib xyaw ua ke uas siv tam sim no, cov ntaub ntawv sib xyaw ua ke ntawm ntau yam khoom no txo cov nqi thiab kev siv hluav taws xob los ntawm qhov ceev pultrusion ntawm 2m / feeb thiab tus nqi voj voog RTM ntawm 2 feeb (lub sijhawm polymerization txo qis 50%).
Qhov project RECOTRANS tau txheeb xyuas cov txiaj ntsig saum toj no los ntawm kev tsim 3 qhov qauv qhia loj tiag tiag, suav nrog:
Hauv cov txheej txheem RTM, cov khoom siv thermoplastic composite ua los ntawm iav fiber thiab thermoplastic acrylic resin tau txais los ntawm kev koom ua ke microwave thev naus laus zis. Tib lub sijhawm, laser vuam siv los ua kom pom kev sib txuas ntawm cov khoom sib xyaw thiab cov hlau. Ua li no, nws yog tsim rau cov tsheb thauj khoom. Cov qauv ntawm lub cockpit rear suspension system.
Hauv cov txheej txheem c-RTM, cov khoom siv thermoplastic composite ua los ntawm cov ntaub ntawv carbon fiber reinforced thiab thermoplastic acrylic resin tau txais los ntawm kev koom ua ke ntawm cov thev naus laus zis microwave, yog li tsim cov qhov rooj tsheb.
Hauv cov txheej txheem pultrusion, cov khoom sib xyaw ua los ntawm cov iav fiber reinforced cov ntaub ntawv thiab thermoplastic acrylic resin tau txais los ntawm kev koom ua ke ntawm microwave thev naus laus zis, yog li tsim cov vaj huam sib luag sab hauv rau kev lag luam tsheb ciav hlau, cov ntaub ntawv sib xyaw thiab kev sib txuas ntawm cov hlau yog ua tiav los ntawm laser vuam.
Ntxiv rau qhov ntawd, qhov project kuj siv 50% cov khoom siv rov ua dua tshiab los ua qhov qhia txog qhov kov qhov rooj kom paub tseeb tias cov khoom siv thermoplastic composite tshiab uas tsim los ntawm kev siv microwave thiab laser welding technology puas siv tau dua tshiab.
